Exhaust gas heaters for

heat recovery from flue gases and directly fired

heater

Heat recovery from flue gases by using the AB Heatec exhaust gas heater AKV

Because of its technical design the exhaust gas heater can be cleaned easily. It is

installed in the flue gas stack of the main diesel engine. The design of the heating surface

consists of coaxially wound coils in which thermo oil circulates and to which the heat of

the flue gas is transferred. The design usually allows for the entire heat demand, for

genera) service and crew accommodation, to be provided.

Directly fired auxiliary AB Heatec heater KV/H for regulating the fluctuations

in heat requirements

When the main diesel engine does not operate (e.g. in the harbour) or when it is

necessary to heat the cargo a directly fired heater with light or heavy oil burner can be

used as a supplement to the flue gas heating. The auxiliary heater may be installed in

serial or in parallel connection depending upon the specific requirements. The plant

operation is in either case fully automatic.

AB Heatec guarantees a trouble free operation

AB Heatec has developed heat transfer systems especially for the particular

requirements of the shipping industry, for example: stress-free-tube suspension and

special multi tube design for vibration and pulsating operation. Because of our long

experience and our highly sophisticated production facilities AB Heatec guarantees for

all systems the highest precision. AB Heatec systems are working reliably and efficiently

on many river and oceangoing ships.

For supplying heating requirements on ships,

thermo oil . heating systems are becoming more

and more commonplace. The reasons for this

development are that thermo oil, compared to

steam, offers many advantages. Because of its

technical and economical qualities as a heat

carrier it is often preferred to steam.

Investment costs and operation costs below the average

Experience proves that the investment- cost for a AB Heatec thermal oil plant are

25 % less than the costs for a steam plant. The energy recovery from the flue

gases is up to 12 %.

Using thermal oil as the heat carrier for the

heater and for the auxiliary heater guarantees

a high system efficiency

The direct fired heater

type KH, which is used

as a back up for the

exhaust gas heater.

The system is easy to

operate and works

automatically.

The advantage of thermal oil

systems in ship operation :

• pressure less operation with open

expansion tank

• no freezing danger during shut

down

• because the system is filled with

thermal oil there is no corrosion

• simple arrangement, similar to

central heating

• exact temperature control, flexible

and easy to adjust

• operation stops and re-starts

are simple

• in contrast to steam systems a

higher efficiency because there

are no condensate losses

• no water treatment is necessary

• energy recovery up to 12% by

using exhaust gasses

• typical investment cost 25%

Than the cost for steam plants

Manufacturing

In order to be able to meet the quality

levels required by our clients and us, the

core components of the AB Heatec plants

are manufactured in Germany by our

factory.

For the manufacturing of large

components, we dispose of production

facilities with a surface of 2,500 m2 and

cranes with an ultimate load of 25 t per

unit. Our machine park is specialised on

the cold forming of tubes up to a nominal

diameter of DN 250 as well as on the

machining of metal sheets up to a

thickness of 25 mm.
