Introduction
This document has been developed in response to the international market need for a specification
relating to the exhaust and heat recovery systems for gas turbines. Purchasers and suppliers will
benefit from a standard against which equipment can be purchased, designed and constructed -
especially given the challenging nature of the turbulent exhaust gas flow and associated complexity of
mechanical design. Equipment is frequently installed in remote and challenging locations both onshore
and offshore where maintenance and repair can be prohibitively expensive.
A waste heat recovery unit recovers thermal energy from the waste heat available in gas turbine exhaust
gases, exchanged into various heat transfer media such as water, water/glycol mixtures, thermal oils
and hydrocarbon gases.
The application of heat recovery devices to gas turbines results in significant thermal efficiency gains
and resultant environmental benefit from reduction in CO emissions. Gas turbine exhaust is one of
many sources of waste heat energy and can be classed as medium grade within a typical temperature
range between 400 °C and 600 °C suitable for Rankine cycle applications.

and other auxiliary equipment.
The supplier shall identify all parts and components with a shorter estimated lifetime than that specified
for the complete system or which will need maintenance and/or removal for service. Expansion joints,
damper, actuators and seals are examples of such components.
6 Basic exhaust system design
6.1 General
GT exhaust systems can be with or without a WHRU and damper system which recovers heat from the
exhaust of a GT and exchanges this heat into HTM to supplement the thermal requirements of another
process. The WHRU enhances the thermal efficiency of the cycle with minimal impact on the operation
of the GT itself.
6.2 Exhaust system configuration
Each exhaust system should normally be connected to its own GT. In the event that more than one GT
is connected to an exhaust system, then special considerations would apply which are not covered in
detail in this document.
6.3 Service life
Unless otherwise stated by the purchaser, the design, selection of equipment and materials and
corrosion protection shall be based on a design lifetime of 20 years with 30 starts/stops from cold to
full load per year. The supplier should supply the service life and minimum uninterrupted operation
interval based on each specific application. The maintenance procedure necessary to achieve these
intervals should also be supplied.
NOTE For highly cyclic GT applications, e.g. in single cycle mode, where the start/stop cycles are significantly
more frequent, the risk of fatigue on various parts of the WHRU increases.
6.4 Supply responsibility
Supply responsibility for the exhaust system should be either with the GT supplier or contracted
directly between the purchaser and the exhaust system supplier.
6.5 GT characteristic data
If the exhaust system is purchased under the GT supplier responsibility then the GT supplier is
responsible to provide the required dimensional, acoustic, thermal, flow characteristics (steady state
and transient) and mechanical information to the exhaust system supplier as specified in this document.
In the event that the purchaser contracts directly with the exhaust system supplier then it becomes the
purchaser’s responsibility to obtain this data from the GT supplier and pass it on the exhaust system
supplier.
6.6 Required operating envelope
The purchaser is responsible to define the equipment’s required operating envelope which should be
shown on the data sheets including any dry run requirements as defined in 9.3.2.
The supplier is responsible for ensuring that all items of equipment and components provided are
designed for the specified operating conditions.
The supplier shall ensure that the equipment takes account of all potential applied loads (typically
seismic, transportation, wind loads, etc.).
6.7 Equipment specification
The exhaust system should be proven in practice, robust, reliable, safe, operable and maintainable.
The exhaust system should be based on the least number of factory-built modules consistent with
transport and site erection dimensional and weight restrictions.
The exhaust system shall be designed and constructed to meet all operational cases specified in the RFQ.
6.8 WHRU equipment specification
Materials of construction for the tube bundle pressure parts shall be selected from internationally
recognized material codes. The supplier’s data sheets shall clearly state the location(s) of each material.
6 © ISO 2020 – All rights reserved
The WHRU shall be designed to provide the required performance with no negative tolerance. The
design shall consider the selected fouling factor and required degree of over-surface to ensure that
these requirements are met.
NOTE The HTM can typically be the following:
(i) a water/glycol solution;
(ii) hot oil/thermal oil;
(iii) water;
(iv) hydrocarbons, liquid or gaseous.
In the final selection of the HTM, due consideration should be given to operating temperatures and
pressures, the degradation limits, surface tension, toxicity, flammability and corrosiveness of the HTM.
6.9 Operating conditions
Each component of the exhaust system (e.g. WHRU tube bundle and supports, casings and linings,
ductwork, dampers, etc.) shall be capable of withstanding the most severe temperature specified plus
a margin as defined in Clause 8.
6.10 Operating environment
The equipment, including all auxiliaries, shall be designed for operation under the environmental
conditions specified by the purchaser. These conditions should include whether the installation
is indoors (heated or unheated) or outdoors, maximum and minimum temperatures, unusual
humidity, and dusty or corrosive conditions, wind, earthquake and/or sea motions during operation
and transport. The unit and its auxiliaries shall be designed for shipment and installation under the
specified conditions.
If sub-zero ambient temperatures are specified by the purchaser, then appropriate materials and test
procedures should be applied.
6.11 Equipment arrangement
The arrangement of the equipment, including piping and auxiliaries, should be developed jointly by the
purchaser and the supplier. It is the purchaser’s responsibility to identify dimensional limitations for
the location of the exhaust system including space required for tube bundle and/or tube removal as well
as any handling weight limitations that apply. The arrangement should be submitted by the supplier to
the purchaser for review and agreement during the proposal phase.
The purchaser is responsible for specifying any weight limitations (e.g. maximum total equipment
weight, maximum lifted weight). If no such limitations exist, at least the total equipment weight with
applicable margin (e.g. ±10 %) should be included in the supplier's proposal.
6.12 Provision for future addition of WHRU
Where specified by the purchaser, the exhaust system shall include provision for future installation of a
WHRU. This should include the bolted panel sized for the full exhaust flow to which a future WHRU can
be connected. It should also include bolted duct section which can be replaced with a future damper or
diverted system.
6.13 Electrical equipment
Motors, electrical components, and electrical installations shall be certified for the area classification
specified (class, group, and division or zone).
6.14 Field assembly and disassembly
The supplier shall state in the proposal the proposed method for the disassembly required for repair
or replacement of exhaust system parts such as expansion joints, WHRU, dampers or silencers. While
tube failures are rare, if specified by the purchaser, the design shall include provision for tube bundle
pressure part repair or replacement.
6.15 Special tools and fixtures
If special tools and fixtures are required to disassemble, assemble or maintain the unit, they shall be
included in the supplier’s proposal and furnished as part of the initial supply of the equipment. For
multi-unit installations, the requirements for quantities of special tools and fixtures should be agreed
between the purchaser and the supplier.
6.16 Spare parts
Spare parts supplied with the main equipment delivery shall be identical to the fitted parts.
6.17 Deviations
All proposed deviations of the supplier’s equipment from this document shall be listed by the supplier
with the bid.
7 Documentation
7.1 General
The supplier should provide all drawings, design details, calculations, and analysis, operation and
maintenance manuals, and other information necessary for the design assessment, erection, operation
and maintenance of the exhaust system installation. All information should be clear and not open to
misinterpretation and shall apply specifically to the installation supplied.
The purchaser should specify which documentation is required to be provided in a local language.
The purchaser should specify the format and number of copies of documentation required from the
supplier.
Unless otherwise specified and agreed by the purchaser all documentation should be submitted in
electronic format.
All calculations and documentation shall be prepared using the agreed unit system for the project.
