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
23 May 2013 Thermal Technical Commission 9
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
23 May 2013 Thermal Technical Commission 13
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
23 May 2013 Thermal Technical Commission 14
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
23 May 2013 Thermal Technical Commission 15
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
23 May 2013 Thermal Technical Commission 16
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.
3.2.11 Insulation on steam pipes and condensate return pipes
23 May 2013 Thermal Technical Commission 17
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
23 May 2013 Thermal Technical Commission 19
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

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.

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.
