EPAT
Boilers and HRSGs
Steam Generator Module provides a heat balance diagram of the
steam generator, which determines heat input, heat output, heat
losses, heat credits, and overall boiler efficiency based on ASME
PTC 4 .0 and 4.4.
The efficiencies of the energy conversion and transfer process
have direct relation to deterioration due to equipment and
operational problems. Early identification of the cause of poor
boiler performance allows affective preventative actions. EPAT’s
assessments identify potential energy and cost savings.

Steam Turbines
Steam Turbine Module determines key performance indicators of
the turbine that provide plant personnel with a comprehensive
picture of the turbine condition. All the calculations for key
performance indicators are based on industrial standards (ASME
PTC 6s).
Component of steam turbines varies corresponding to the design
of the plant. Typical components for steam turbine are:
HP turbine
LP turbine
IP turbine
Deaerator
Feedwater heater
Electrical generator

Gas Turbines
Performance deteriorates against time is a normal phenomenon
for all machines including gas turbines during operation. The
deterioration results in loss in power output and increase fuel
consumption. The subsequent impacts such as lower production
and higher operating costs will effect negatively on company’s
revenue and profits. Thus, accurate assessments of the capability
and operating conditions of the GT are essential.
EPAT provides performance monitoring under varying ambient
conditions, based on industrial standards (ASME PTC 22) and
Performance Test Reports from Machine Manufacturer.

Compressors
Studies on turbo machinery’s life cycle costs have shown that
energy costs normally far outweigh the procurement, installation,
and maintenance costs. This has led to an increased awareness
of the values of efficiency, capacity flexibility, and performance
analysis and monitoring, in addition to the traditional values for
reliability.
All the calculations for key performance indicators are based on
industrial standards (ISO 5389 and ASME PTC 10), as well as
Performance Test Reports from Machine Manufacturer.

Other Equipments
There are many other equipments which EPAT can assess them.
All the calculations for key performance indicators are based on
industrial standards. Components of utility cycle vary
corresponding to the design of the plant. The other equipment
modules of EPAT are:
Pump
Fan
Single Phase Heat Exchanger
Condenser
Cooling Tower
Air Cooler
