Combined Cycle Power Plants
As the most efficient of the currently available
thermal power generation technologies, gas
turbine based combined cycle power plants are
the technology of choice for flexible, utility scale
power generation. Apart from the high efficiency
compared to traditional steam boiler plants,
combined cycle plants offer advantages in terms
of their relatively low environmental impact, high
level of flexibility and shorter project imple-
mentation times.
METKA’s experience covers both single shaft and
multi shaft configurations, and a wide range of gas
turbine models including both heavy duty
industrial and aeroderivative types. Single shaft
configurations, with the gas turbine and steam
turbine on the same axis, connected to a single
generator, have an advantage in terms of the
compact layout. Multi shaft configurations may
have one or more gas turbine generators, together
with a single steam turbine generator. Our most
recent projects are based on the latest generation
“F” class gas turbine technology from the leading
OEMs, including GE, Siemens, Alstom and Ansaldo,
providing extremely high plant efficiency.
METKA combined cycle solutions use well-
established reference plant concepts as a basis for
the design, with flexibility to meet client needs, as
well as other local market and project specific
requirements. We work closely with the power-train
manufacturer so that proven product developments,
and lessons learned from previous operating
experience, can be built into the plant design. The
latest technologies and operating philosophies are
therefore available in such areas as:
– Plant flexibility, such as start-up / shut-down
times and cycling operations to enhance
economic dispatch of the plant
– Performance improvements, including tech-
niques, such as natural gas pre-heating, inlet
air chilling, part-load efficiency optimization
– Emission controls, using the latest NOx reduction
techniques
With experience of numerous combined cycle
projects, and several different configuration types,
METKA has the expertise to ensure that all plant
components are properly selected, leading to a
well integrated plant design and reliable long-term
plant operation.
METKA has significant expertise in gas turbine based power
plants, with a broad range of experience in combined cycle,
co-generation and simple cycle projects. We provide our
customers with highly competitive combined cycle plants
with world-class performance.

We apply
sophisticated
3-D modelling
tools to
produce
highly
integrated,
detailed plant
designs.
This improves
design quality,
and reduces
construction
time for your
investment.
These tools
also allow
operations
and
maintenance
aspects,
such
as equipment
accessibility,
to be
considered
during
the design
stage.
