3. Matters arising from the minutes not already

included in the agenda


5.1. BREF – Best Available Techniques Reference Documents at EU level – a

presentation for discussion

5.2. ISO 50001 and the Energy Efficiency Directive to become active in 2014

(briefing and discussion by Andreas Gürtler)

5. Advocacy and Lobbying on international and

national levels


4. Approval of the agenda / desired changes



The Joint Research Centre of the EU is working on so called

Best Available Technique Reference Documents.

These Documents are part of the International reference documents that have been

drawn (or are planned to be drawn) as part of the exchange of information carried out in

the framework of Article 13(1) of the Industrial Emissions Directive (IED).

Industrial insulation (information from Eurima)

Starting 2015, the European Commission will develop a BREF note on resource

efficiency in industry. This BREF (Best Available Technique Reference Note) is the

implementation of the Industrial Emissions Directive, previously IPPC Directive. There

is already a BREF note on energy efficiency in industry (2009) but this energy efficiency

BREF note will be updated and extended to other areas.

BREF Documents

For each BREF, the European IPPC Bureau sets up a Technical Working Group (TWG)

to carry out the exchange of information on BAT. A TWG usually consists of between 40

to 100 experts.

The European IPPC Bureau organises the work of the TWG, fosters the exchange of

information, makes a scientific and technical analysis of the vast amount of information

exchanged, proposes compromise solutions on issues when views of TWG members

differ, and writes the BREF.

The European IPPC Bureau acts as a neutral, technically competent and permanent

body to all TWGs.

Working procedures to elaborate BREFs

23 May 2013 8


The procedure used to elaborate or review a BREF includes a few plenary meetings of

the TWG, sub-group meetings, visits to installations, and submission of draft BREFs for

comments.

Practical arrangements for the exchange of information are laid down in the specific

guidance documents referred to in Article 13 (3)(c) and (d) of the Industrial Emissions

Directive (IED), 2010/75/EU.

These documents aim in particular at guiding the European IPPC Bureau and members

of the technical working groups (TWGs) in the drawing up and reviewing the whole series

of BREFs.

Once it has been finalised, each BREF is presented by the European IPPC Bureau to DG

Environment at the forum (Information Exchange Forum, IEF) established by the IED (ex

IPPC Directive) .

Ensuring insulation is optimised

Description

The heat losses through the walls of the combustion system are determined by

the diameter of the pipe and the thickness of the insulation. An optimum

insulation thickness which relates energy consumption with economics should

be found in every particular case.

Efficient thermal insulation to keep heat losses through the walls at a minimum

is normally achieved at the commissioning stage of the installation. However,

insulating material may progressively deteriorate, and must be replaced after

inspection following maintenance programmes. Some techniques using infrared

imaging are convenient to identify the zones of damaged insulation from

outside while the combustion installation is in operation in order to plan repairs

during shutdown.

3.1.7 Reducing heat losses by insulation


Achieved environmental benefits

Energy savings.

Cross-media effects

Use of insulation material.

Operational data

Regular maintenance and periodical control is important to check the absence

of hidden leaks in the system (below the insulations). In negative pressure

systems, leakage can cause an increase of the amount of gas in the system

and a subsequent demand of electrical power at the fans.

3.1.7 Reducing heat losses by insulation


3.2.1 General features of steam

Distribution: the distribution system carries steam from the boiler or generator

to the points of end-use. Many distribution systems have several take-off lines

that operate at different pressures.

These distribution lines are separated by various types of isolation valves,

pressure-regulation valves, and sometimes backpressure turbines. Effective

distribution system performance requires a proper steam pressure balance,

good condensate drainage, adequate insulation and effective pressure

regulation.

3.2 Steam systems


Steam pipes and condensate return pipes that are not insulated are a constant

source of heat loss which is easy to remedy. Insulating all heat surfaces is,

in most cases, an easy measure to implement.

In addition, localised damage to insulation can be readily repaired. Insulation

might have been removed or not replaced during operation maintenance or

repairs. Removable insulation covers for valves or other installations may be

absent.

Wet or hardened insulation needs to be replaced. The cause of wet insulation

can often be found in leaking pipes or tubes. The leaks should be repaired

before the insulation is replaced.

3.2.11 Insulation on steam pipes and condensate return pipes


A reduction of energy losses through better insulation can also lead to a

reduction in the use of water and the related savings on water treatment.



Cross-media effects

Increased use of insulating materials.

Applicability

As a baseline, all piping operating at temperatures above 200 °C and diameters of more than 200 mm

should be insulated and good condition of this insulation should be checked on a periodic basis (e.g.

prior to turnarounds via IR scans of piping systems). In addition, any surfaces that reach temperatures

of higher than 50 ºC where there is a risk of staff contact, should be insulated.

Economics

It can give rapid payback, but time depends on energy price, energy

losses and insulation costs.

Driving force for implementation

Easy to achieve compared to other techniques. Health and safety.

Examples: Widely applied.



7.10.1 Steam

Example 1 Insulating valves

Insulating a single 100 mm valve controlling steam at 800 kPa (8 bar) (175 ºC)

located indoors would reduce heat losses by 0.6 kW. This would reduce boiler

fuel costs by EUR 40/year and give an energy saving of 5 MWh/year.

For Johnson Matthey Catalysts in Teesside, UK, the fitting of insulation jackets

to valves and flanges have resulted in:

• annual energy savings of 590 MWh

• carbon savings of 29 tonnes/year

• payback period of 1.6 years.

7.10 Chapter 3 examples


As the EU is planning to update the BREF energy efficiency document and

furthermore will start in 2015 to develop a BREF note on resource efficiency

in industry it might be beneficial if FESI would send an insulation expert to the

Technical Working Groups (TWG) of this BREF.

1. Anyone interested to join this EU TWG?

2. How can FESI support the development process?

3. Shall we set up a FESI TWG to prepare and support the representative?

Article 1

Subject matter and scope

1. This Directive establishes a common framework

of measures for the promotion of energy efficiency within the Union in order to

ensure the achievement of the Union's 2020 20% headline target on energy

efficiency and to pave the way for further energy efficiency improvements

beyond that date.

It lays down rules designed to remove barriers in the energy market and

overcome market failures that impede efficiency in the supply and use of energy,

and provides for the establishment of indicative national energy efficiency targets

for 2020.

Energy Efficiency Directive

Article 8

Energy audits and energy management systems

1. Member States shall promote the availability to all final customers of

high quality energy audits which are cost-effective and:

a. carried out in an independent manner by qualified and/or

accredited experts according to qualification criteria;

or

b. implemented and supervised by independent authorities

under national legislation.

6.1. Produce a punchy new short summary document (and subsequently a

presentation) on the way to minimise/eliminate CUI by effective inputs and controls

at the design, installation and maintenance stages of insulation systems.

6.2. Review FESI Technical Document 10 and update it.

6.3. Subsequently produce a power point presentation for management levels to

show that a quality insulation system is an excellent investment.

6.4. Consider initiatives to promote the installation of quality insulation systems to

prevent/minimise CUI: These might include a study on the repair/replacement of

equipment costs due to CUI which could be avoided with a quality insulation system,

properly designed, installed and maintained.
