China power will affects US

catalyst prices

Most people wi thin t he indust ry wi ll recognise that HRSG is essential ly a heat exchanger

which recovers heat f rom a hot gas st ream. Indeed, in a combined-cycle power stat ion HSRG

produces electricity more efficiently than either gas turbines or steam turbines alone.

When it comes to reducing poll ut ion, the HRSG's emissions control sector contains a Select ive

Catalytic Reduction system to either reduce nitrogen oxides or employ a catalyst to remove CO. In

fact, the inclusion of an SCR dramatically effects the layout of the HRSG.

What det ermines the market price of t hese kinds of catalysts? Whether i t 's consumables such as

activated carbon or SCR catalysts, it wil l soon be Chinese activi ty which determines the price. This

is the conclusion reached by the Il li nois-based McIlvaine Company based on it s latest forecasts and

demand analyses.

"The reality is that a power plant in the US should plan its catalyst purchases based on two

factors. First ly, the demand in China will be larger than the present world capacity. This wil l

increase cost in the short -t erm. Secondly, t here wil l be new Chinese suppliers entering the US

market which will decrease price in the longer term," says the latest McIlvaine report.

The US has averaged 10,000 megawat ts (MW) per year of new SCR NOx cont rol systems since 1991,

say the researchers. Outside China, ot her nat ions have only managed t o has managed to install

300,000 MW of these systems since 1980.

Here's the crux of the issue. China apparentl y plans to instal l 400,000 MW by 2020 and it has -

over the last few years - installed more MW of SCR than any country apart fr om the US. It s

estimated that by 2020 the Chinese demands for catalyst will be 25%greater than the present

worl d manufact uring capacity. By 2012 Dongfang and Sino Environment will have combined

manufacturing capacity in China of 23,000 m3 but this will be only 15%of the 2020 requirement.

Over t he past 40 years the worl d outside China has managed to i nstall 382,000 MW of fl ue gas

desulfuri zat ion scrubbers. In less than 10 years China has instal led 326,000 MW and by 2020 China

will be operat ing 658,000 MW of FGD Systems. This means that i t wil l require twi ce the limestone

used in plants outside China today on the worl d market . It wil l also need to buy more slurr y

pumps, nozzles and agit ators than are current ly used in FGD systems in t he world today.

This high level of act ivit y wil l result in t he shortage of some raw materials, especially i n the US,

unless US industr ial output in t hese sectors is adjusted accordingly.

So - does thi s meangood news or bad for al l cat alyst users in the US by 2020?

Only time will tell.

DIESEL ENGINES

First unveiled in 2006, C175 diesel

generator sets have successfully

completed ri gorous field reli abil it y

demonst rat ions in appli cati ons spanning

the globe, says the US-based

manufacturer, Caterpi ll ar.

Its latest development - introduced for

standby, prime and continuous

applicati ons - i s the C175-16 diesel

package generator set. It is now available

worldwide in 60 Hz packages with ratings

up to 3.1 MW and 50Hz packages wi th

rat ings up t o 3.1MVA.

The Cat C175-16 generator set package

was designed to offer a larger unit rating,higher power density, lower emissions and

reduced install at ion costs. Meet ing US EPA

Tier 2 requirements, the new generator

set addresses current and fut ure needs of

the worldwide electric power industry,

says Caterpi ll ar.

The C175 diesel generat or sets have

achieved more than 100,000h of proven

reliability across all Cat product lines,

with over 60,000h in generator set

applicat ions. The C175 has been used for

applications ranging from distributed

generation to prime power for remote

communit ies, indust rial processing plants

and rock crushing applicati ons.

Darrin Heflin, engineering manager for

the C175, told AIP: "Our customers wanted

more power in a smaller package. In

today's economic climates, customers

expect their generator sets to deliver

improved performance and low fuel con-

sumption, while meeting future emissions

regulations.

He said: Caterpi ll ar's answer i s the

C175, designed to provide a reliable,

durable, easily serviceable generator set

in a single solid package."Five key engine systems comprise t he

Cat C175-16: fuel system, elect ronics and

controls, air system, cooling system and

More power in a smaller package -

an evolution in diesel gen-setsThree years after the launch of the basic model, the C175, Caterpillar Inc. has

developed an improved C175-16 diesel package generator set for standby, prime andcontinuous applications. This offers improved performance and low fuel consumption,

while meeting future emissions regulations, says the manufacturer.

lubrication system. The C175-16's fuel

system uses a high-pressure fuel pump

and control valve which deliver multiple

precise inj ections wit hin a single

combust ion event. This result s in lower

emissions, improved performance and

reduced fuel consumption. Driven by the

ADEMA4 cont rol ler, t he C175-16 engine

management system provides superior

performance even in the most demanding

environments.

Both hard-wired control signals and

redundant data links offer reliable control

and communicati on between engine

systems. The air system delivers cooler

combustion air at the cross-flow cylinder

heads, allowing for higher power densit y

and emission reduct ion.

A new generat ion of t urbochargers was

designed for the C175, providing a 5%efficiency boost and longer life when

compared to traditional turbochargers. A

newly-designed cooling system cools only

the parts of the engine which require

cooling, resulting in increased efficiency

and lower heat rejection. This method of

temperature control allows customers to

reduce overall operating costs by using

smaller radiators.

The lubr icat ion system uses a range of

Cat advanced high-efficiency oil filters

which provide a higher level of f il tr ation

efficiency while maintaining the Cat

superior capacity, reports the company.

By enhancing the lubricat ion system, t he

traditional 500h oil drain interval has

been changed to 600h.

It may be possible to extend this even

furt her wit h the use of Cat S-O-S Services.

This will result in reduced maintenance

expenditures and downtime, says

Caterpillar.

CHP

American Honda Motor Company's

headquart ers covers an area of

more than 100 acres, and includes

12 buildings with nearly 1.5 million square

feet of mixed-use office space for 3,000

workers. Honda This part icular CHP powersystem (ri ght ) fulf il ls a corporate aim - to

generate its own electricity for its campus

at a lower cost, both fiscally and

environmentally, using natural gas. It now

produces 1.25 MW of elect ri cit y and 10

MMBtu of heat per hour to operate an

absorption chiller and provide offset

power.

A spokesman for the dist ributor,

Cummins Cal Pacific, commented: "What

this does is to save up to 30%annually on

total campus energy expenditures and

demonstrate corporate leadership and

environmental responsibi li ty. TheAmerican Honda headquarters gets t rue

mil eage wit h a CHP system from Cummins

Power Generat ion. "

Gart h Sell ers, American Honda's

manager, national facil it y management,

told AIP:. "Our decision to install

cogeneration was an entirely logical one -

it took our environmental commitment a

step further. It was time to begin

generating our own power."

The CHP system for American Honda

consists of a 1250 kW PowerCommand

QSV91G gas engine generat or fromCummins Power Generation, plus three

Mueller heat exchangers which capture

over 10 million Btu per hour of waste heat

in t he form of hot water from the engine

exhaust , engine coolant and oil systems.

The hot water is used to run an

absorpt ion chil ler.

"Our decision to install cogeneration was

an entirely logical one - it took our

environmental commitment a step further.

It was time to begin generating our own

power."

The PowerCommand QSV91G generat ing

set instal led at American Honda is one ofthe cleanest gas generat or sets available

today, says Cummins. Wit hout af ter-

For most energy-generation specialists, it's not the sleek cars or bikes which will turntheir heads at America Honda's HQ in Torrance, CA, - but the impressive onsite CHPhardware providing offset power, AIP reports.

generat or's emissions of NOX are 111 part s

per mil li on by volume (0.85 grams/ BHP-

hr). This level of emissions meets air-

quali ty standards in most part s of t he US.

However, to meet California's strict air-

quality standard, the generator's exhaust

needed to be treated.

Cummins Cal Pacific designed and

installed a selective catalytic reduction

(SCR) system on the generator set's

exhaust which uses a urea inj ect ion to

reduce the NOX in t he engine's exhaust.

Following treatment, NOX in the exhaust

st ream is reduced to less than 14 part s

per million by volume in compliance with

the state standard.

The CHP system is install ed in American

Honda's Central Plant building, which

houses the ot her mechanical systems for

the campus.

Current ly, t he CHP system supplies 100%

of the electrical needs of the Central

Plant building for most of the year, but

the cold water from the chiller iscirculated throughout the entire 12-build-

ing campus for air condit ioning.

Sellers reports t hat the CHPsystem

operates only during the daytime for now,

but American Honda willultimately run the

system 24-hours-a-day, seven days a

week, in Phase Two of t he proj ect when

two more buildings will be fed from the

generator.

The campus has a total electrical load of

5.2 MW and, with the addition of the CHP

system which runs only dur ing business

hours, utility power consumption

decreased 14%during the first year of

operation. "When we first looked at this

proj ect, the key was to do away wit h kW

demand costs from t he uti li t y,"says

MICROGENERATION

How easy is it for an entire town to

become self-sufficient? That's the

quest ion t hat Reynolds, Indiana,

has been trying to answer f or t he past

four years. In 2005 Indiana Governor Mitch

Daniels famously nicknamed the townBioTown, USA - a model of energy self -

suffi ciency for the enti re state.

The town was chosen mainly because of

it s small size (populati on 547), excell ent

rail and road access, and proximity to

organic waste (within 15 miles of more

than 150,000 hogs).

The finished proj ect showcases eff icient

methods of converting biomass into

energy, use bioenergy to fuel homes and

businesses throughout the town, promote

alt ernat ive energies across the US and

show that agricult ural energy is safe,

reliable, and consistent.These are certainly some lofty goals for

such a tiny town, and progress on the

project has been slow. In fact , external

signs of energy independence in Reynolds

have been few and far between. So where

does the proj ect stand now?

As of June 9th, 2009, t he Whit e County

Area Planning Commission vot ed t o

recommend approval of a re-zoning to

allow construction of a methane gas-

producing digester. This would use animal

and human waste to create methane,

which would power local homes andbusinesses.

However, there are still many hoops for

the t own to j ump through before

achieving energy independence. Whil e the

proposed methane digester wil l be useful,

it may not be enough. And even if it is,

the Whit e County Commissioners st il l

need to ult imately decide whether t o

approve the re-zoning request.

Reynolds is a prime example of why

communit ies need to prepare for energy

crises far in advance. If it takes a

prominent proj ect such as BioTown, USA,

nearly five years to achieve its goal - witha population of 547 - how long will it take

grassroots ini t iat ives in larger towns and

cities?

BioTown, USA - Reynolds, Indiana

It's easy enough for one person to try energy self-sufficiency through microgeneration: puta solar panel on your roof, run your car on biodiesel and you're halfway there. But how

easy is it for an entire American town to become self-sufficient? AIP has the answers.

Indiana Agricult ure Director Andy Mil ler

commented:

"The purpose of BioTown is to creat e a

model community which is energy self-

sufficient. BioTown will create a cleaner

environment, develop new markets andenhance value for Indiana waste products

whil e producing it s own energy. Our goal

is to make Indiana a leader in the future

of agriculture and, to do that, we must be

progressive in advancing new uses for all

our products and finding more

environmentally-friendly ways to

dispose of our byproducts."

CONTROLS & MONITORING

Power companies have to deliver

more electri cit y f rom renewableenergy sources to customers by t he

end of the decade. Thats really the

bot tom li ne behind a US$87m order ABB

won in Los Angeles, California. The

companys technicians are now busy

increasing the capacity of the 23-year-old

Intermountain Power Proj ect Southern

Transmission System by 25%t o 2,400

megawatts by 2010. This upgrade is a vit al

part of the developments plans of the Los

Angeles Depart ment of Water and Power

(LADWP). As if this wasn t hard enough, at

least 75%of capacity has to be

maintained during the refurbishment.

"This project is very much in line with

our focus on increasing energy efficiency

and leveraging the power of renewables,"

Peter Leupp, head of ABB's Power

Systems, told AIP.

Six months ago t he Intermountain Power

Agency and LADWP, the operat ing agent ,

selected ABB to upgrade the high-voltage

direct current (HVDC) system wit h a

state-of-t he-art control and protecti on

system, MACH2.

ABB also has to provide efficient cooling

systems for the valves which convert thecurrent from AC to DC and back, and

additional AC filters to strengthen power

supply quality.

The cont rol system is the brain in an

HVDC t ransmission system. One maj or

advantage of a HVDC t ransmission i s it s

controll abil it y, reports Leupp.

The basic power control is achieved

through a system where one of the

converters controls its DC voltage and the

other converter controls the current

through t he DC circuit .

The control system acts through firing

angle adjustments of t he thyristor valves

and through tap changer adj ustments on

the converter transformers.

Controls & Monitoring - a mega-

upgrade for LADWP is underwayABB is working to increase the capacity of the Intermountain Power Project SouthernTransmission System by 25% to 2,400 megawatts by 2010. AIP looks at the MACH 2

control & protection systems which are central to the US$87m upgrade by the LosAngeles Department of Water and Power (LADWP).

Each pole in a bipolar ABB HVDC link has

its own control system and each control

system is duplicated.

In the normal mode, the control systems

of the two stations of a two-terminalHVDC system communicate with each

other through a telecommunication link

between the stations. Most of the ABB

HVDC t ransmissions are remotely

controlled from a dispatch centre for the

grid.

With MACH2all functions for control,

supervision and protection of the stations

are implemented in software running in a

family of microprocessor cir cuit boards.

Peter Leupp explained: Today the

MACH2 is used in convent ional SVC, HVDC

and SVC Light and a number of other

applications.

The most i mportant part of t he control

system, the converter firing control, is

built around a host 1.3 GHz Pentium III

dual-processor system and six high

performance digital signal processors

(SHARC). The open systems st rat egy in

MACH2is ref lect ed both in t he use of

indust rial standard serial and parallel

communication buses, as well as in the

use of standard formats for all collected

data (such as events, alarms and

disturbance data).

All critical parts of the system are

designed with inherent parallelredundancy in accordance wit h principles

used by for HVDC since t he earl y 1980s.

The redundant systems are designed as

duplicated systems acting as active or hot

standby. At any time only one of the two

systems is active, controll ing the

converter and associated equipment.

The other system, the standby system, is

running, but the outputs from that system

are disabled. If a fault is detected in the

active system, t he standby system wil l

take over the control, with no disturbance

to the t ransmission, says ABB.

FILTRATION

With increasing implementation of

Selective Catalytic Reduction

(SCR) for NOx reduct ion, there

are higher concentrati ons of SO3 in the

fl ue gas. In additi on to forming a blue

plume after exiting the stack, SO3 can

react wi th NH3 to form st icky (NH4)2SO4(ABS) t hat can plug up the air preheater.

Furthermore, SO3 can pose serious

corrosion problems to air preheater,

electrostatic precipi tator (ESP) and down-

stream equipment . Among vari ous SO3

mitigation technologies, dry injection of

sodium sorbents, such as trona, has been

proven to be very effective and cost-

competitive.

While wet scrubbers have been used to

cont rol SO2 for l arge boilers, they are t oo

capital-intensive for small boilers.

In addition, many small boilers do nothave enough available space for the

installat ion of a wet scrubber. Dry

sorbent inj ect ion (DSI) systems using t rona

or sodium bicarbonate are used for SO2

control for years to effectively remove

SO2 at rates as high as 95%.

The advantages of dry inj ection of t rona

or sodium bicarbonat e for SO2 and SO3

include (a) low capital cost; (b) small

installation f ootprint; (c) ease of

operation; and (d) mult i-pollutant cont rol.

In a DSI system, a fine powder, such as

t rona (Na2CO3 lNaHCO3l2H2O) or sodium

bicarbonate (NaHCO3), is inj ected intothe flue gas duct. Aft er injecti on, either

sodium sorbent is calcined into porous

sodium carbonate (Na2CO3) which react s

with acid gases, such as

SO2, SO3, HCl and HF.

The resulting products

(Na2SO4, NaCl and NaF)

are collected by the

particulate control

device, such as an ESP orbag filter.

The sorbent can be

inj ected at almost any

location as long as the

flue gas temperature is

above 275F. In the case of SO3 control ,

if t he sorbent is inj ected upst ream of

SCR, most SO3 wi ll be removed before

entering the SCR catalyst and can conse-

quently lower the Minimum Operation

Temperature (MOT).

No supplemental water injection is

needed when using sodium sorbents,unlike the approach using lime or

hydrated lime. A simple blower is needed

to deliver the sorbent into the duct

through inj ection lances.

The key of DSI system design is to

distribute the sorbent evenly in flue gas

so that the sorbent and acid gases can be

well mixed.

Trona (SOLVAir Select 200) i s a

naturally occurring mineral with a

chemical formula of NaHCO3-Na2CO3-

2H2O. Since it is produced as a fine

powder, it is not necessary to mill trona.

Although milling can increase the removalefficiency, the added cost of equipment

and maintenance have discouraged most

users from using mills.

VALVES & PUMPS

Users of control valves in

power-generating facilities - asyoud expect - have to be

particularly picky about their components.

Indeed, operators in the USA and the UK

have been happy to provide evidence

from the field t hat the Rotork CVA electric

actuator is living up to the demanding

expectati ons of end-users, says the

manufacturer.

"The CVA is working perfect ly, i t holds

the set point, no deviation and responds

very quickly to a change," explains a

spokesperson from a major power plant in

the Boston area of t he USA.

Controlled by a 4-20mA signal, the CVA is

currently installed on a three-way two-

inch hot water blending valve in the

station's demineralisation plant.

The electric actuator has replaced a

spring diaphragm actuator and pneumatic

positioner that had proved to be

unreliable and suffered from exposure to

the harsh conditi ons which are

synonymous with power station

environments. The operators are now

also able to close the valve at the end of

a cycle for isolation of the hot water

tank, which they couldn't do before dueto t he unreliabilit y of t he posit ioner.

"It does exactly what we want for

posit ioning. We don't even know it is

there," concludes the spokesperson, who

is now considering the CVA for fur ther

applications in the plant.

In t he UK, Drax Power Stat ion has a CVA

installed on a one-inch globe control valve

which regulates the direct steam inlet

temperature in the boiler f uel oil pump

house.

The CVA replaced a pneumatic actuator

and posit ioner and operates from t he

same 4-20mAsignal. Operat ions have

been a success, with zero deviation from

the desired value to the measured value

Control valve automation systems -

the key to power generationWhat you really need for rugged, extreme environments found in cogen power stationsare highly-accurate control valve automation systems which combine advanced, non-

intrusive calibration, valve diagnostics with the simplicity, user-friendliness and economyof electric operation. AIP has the story.

and, as a result, the operators are looking

at t he CVA as an opti on for future cont rol

appli cations at the station. Another

factor in its favour has been the ease with

which it was installed on the existing

valve.Available for the direct-drive actuation

of linear or quarter-turn control valves,

the CVA demonst rat es highly accurate

control valve automation, combined with

advanced, non-intrusive calibration, valve

diagnost ics and t he simpli cit y, user-f riend-

liness and economy of elect ric operation.

Mechanical features include the Rotork

'double-sealed' enclosure, whereby

internal electrical components are

permanent ly protected from t he effects

of the operating environment.

The IP68 dust tight, water tight and

temporarily submersible (7 metres, 72

hours) enclosure is universal to all models

in t he CVA range, i ncluding those wit h

hazardous area approvals. The CVA is

engineered t o deliver high precision valve

FUEL CELLS

Fuel cell technology is tipped to be

the largest, 'new' industry of the

21st century, with fuel cells

anti cipat ed to become a common source

of power for backup systems as well as

vehicles, homes and public andcommercial buildings.

Xin Li, Technical Specialist, Cummins

Power Generation predicts that on the

basis of current progress Solid Oxide fuel

cell-based mobile power products will be

commercially available wit hin two t o

three years, with higher powered (>

100kW) stationary power units becoming

commerciall y available wi thin 7-10 years.

Functioning like a battery which uses

electrochemical conversion, fuel cells

produce electri city f rom fuel (on the

anode side) and an oxidant (on t he

cathode side)which react in t he presence

of an electrolyte. Fuel cells can be used

in a variety of applications including base

load power plants, electric and hybrid

vehicles, auxiliary power, off-grid power

supply and portable charging docks for

small electronics.

Solid Oxide Fuel Cells (SOFC) which

operate on a mixture of hydrogen and

carbon monoxide are more compatible

with existing fuel infrastructures including

natural gas and the only byproducts are

water vapour and a small amount of

carbon dioxide.

In 2007 Cummins Power Generat ion was

one of six industry teams involved in the

DOE SECA programme t o successfully

complet e the Phase One tests of t he fi rst

Solid Oxide Fuel Cell prot otypes.

"These units offered the potential to be

manufactured at costs approaching to

conventional stat ionary power-generation

technology", recalls Xin Li, whose

significant contribution to the design andimplementation of the low cost air supply

system for fuel cell, helped achieve over-

all system costs and performance meeting

The latest fuel cell - a dream realised

Research into fuel cell technology is gathering momentum and making a significantcontribution to the evolution of a revolutionary, ultra environmentally-friendly way ofgenerating electricity, reports Xin Li, Technical Specialist for Cummins Power.

aggressive DOE target s. The

resulting solid oxide fuel cell

(SOFC) power system (developed

with Versa Power) has the

potential to directly and

seamlessly replace its diesel

powered generator sets in many

applications. It can provide

virtually silent power with

significantly lower fuel consump-

t ion and exhaust emission t han

existing generator sets.

Addit ional benefi ts should include higher

reliability and lower maintenance than

today's systems. The protot ype unit tested

for SECA produced t hree kil owatt s of

electrical power while operating on com-

mercial pipeline natural gas and ran

flawlessly for over 2,000 hours at

Cummins Power Generat ion's test faci li ty

in Minneapolis, Minnesota.

It demonstrated an efficiency of over

37%, which compares favourably wit h

comparably-sized small IC engine-based

generator sets, where efficiency is

generally well below 30%or even lower.

Commenting on the advantages of the

SOFC system Xin Li says: "There are many

benef it s to SOFC-based energy. The

technology represents a highly efficient,

clean emission (no exhaust t reatment

required) source of high quality AC power,

which is compatible with other energy

resources such as Diesel Generat or Sets,Solar and Wind. The power out put is quiet

making it socially more attractive than

traditional engine driven generator sets,

with low vibration levels, and the whole

system boasts the added appeal of l ow

maintenance.

He report s: SOFC technology can

provide a reliable power generator

solution for a range of applications. In the

case of CHP, in addit ion t o the signif icant

green credenti als, the possible f inancial

savings to t he consumer are considerable.

For example, f or home CHPappli cations

the natural gas powered SOFC system can

deliver over 70%efficiency.

In addit ion to the SECA program,

Cummins Power Generat ion has been

worki ng wit h t he USDOE's Energy

Efficiency and Renewable Energy (EERE)

office to develop and demonstrate a

prot otype SOFC mobile auxili ary power

unit configured to provide electrical

power for cab auxiliary loads in

C O N T R A C T S & A P P L I C A T I O N S

Emerson Process Management has complet ed a dual

fuel-conversion initiative which has enabled the

Termocandelaria power plant to operate using eit hernatural gas or oil. The proj ect, implemented by

Emerson and Mit subishi Power Systems Americas

(MPSA), went int o commercial operation in j ust 11

months, an aggressive timetable required in order

for Termocandelaria t o fulf il l it s regulatory

obligations. The proj ect marks the lat est

collaborat ion bet ween Emerson and MPSA, whi ch in

2008 formed an alliance for turbine retrofit

projects.

Termocandelaria, owned by Termocandelaria Power

Ltd., is a two-unit, 320-MW power plant located in

Cart agena, along Colombia's Caribbean Coast .

Convert ing t he plant 's two West inghouse 501F

turbines from gas fuel only to dual-fuel operationoffered Termocandelaria a low-risk, cost-effective

strategy for improving unit startup reli abili ty.

By being able to start reliably and generate the

requested power on demand, Termocandelaria not

only maximises it s generat ing revenue but also

avoids financial penalties that would be incurred if

it were not able to fulfill its regulatory obligations

with the Colombian Energy System.

The Colombian electricity market is served

primarily by hydro-electric plants located in the

center of the country. When there is drought,

t ransmission i ssues or high demand, t hese plants are

not always able to generate sufficient power to

meet t he region's needs. In t hese instances, t heColombian government typically calls on power

plants uti li sing other fuel sources, such as

Termocandelaria, to provide addit ional megawatt s.

"Startup reliabili ty has been great ly enhanced wit h

the dual-fuel capability now in place,

Termocandelaria is able to produce megawat ts on

demand," Miguel Angel Perez Ghisays, Plant

Manager, Termocandelaria, told AIP."The significance of this cannot be

underestimated, as the plant's ability to be a

reli able source of back-up power plays an important

role in maintaining grid stability."

For t his proj ect , Emerson co-developed wit h MPSA

a new control strategy for the dual fuel conversion,

which included logic f or water i njecti on, fuel gas

and fuel oil systems. In addition to the new logic

required t o accommodate a second fuel source,

Emerson also migrated the existing gas turbine

controls from the previous-generat ion WDPF

distributed control system to its Ovation expert

control system. As part of the migration, Emerson, a

leader in power plant automation and turbinecontrol solutions, converted the existing logic to

industry standard SAMA logic. This wi ll enable

Termocandelaria to more easily modify control

schemes in t he fut ure.

Cogeneration fuel cell from TognumA new cogenerati on fuel cell system from the Tognum brand MTU

Onsite Energy is currently creating a stir in the brewery sector.

The HotModule HM300 distributed energy system generates electrical

power and heat from biogas. The electrical power output is about

240 kW whil e the thermal output is more than 200 kW.

"This innovative fuel cell serves to combine what is sensible in termsof energy policy wi th what i s necessary for climate protect ion.

Global warming and the decline in fossil fuels not only require a

consistent expansion in the use of renewable energy sources, but an

increased uti li sation of eff icient and innovative t echnologies,

commented Karl-Theodor zu Guttenberg.

"We are continuously looking for possibilities to use energy more

efficiently and to become less dependent on fossil fuels", adds Peter

Liebert, Managing Director of the

Engineering segment of the private

brewery involved.

Biogas is a byproduct of the brewing

process with an 85 percent methane

content, making it an excellent

energy source for the fuel cell - a

regenerative and almost cost-freewaste product, facilitating annual

CO2 reductions of up to 1,200 tons,

says Tognum.

A gas cleansing system also

developed by Tognum subsidiary MTU

Onsite Energy Fuel Cell Systems

removes possible sulphur residues

from the biogas which would

otherwise be detrimental to the fuel

cell stack. At a temperature of

approximately 650C, the biogas is

then convert ed into hydrogen which reacts electr ochemically wit h

the airborne oxygen. Almost 50 percent of the biogas energy

content is converted into electrical power, while more than 40

percent t ranslates into waste heat , which has a temperature ofroughly 400C. Taken together, the result is an exceptionally

st reamlined overall eff iciency of more t han 90 percent .
