The modular package concept of the
THM gas turbine range enables each
gas turbine generator unit to be cus-
tomized to the requirements of the
application.
The package design shown here re-
presents one possible variant.

Due to their high reliability, THM gas
turbines are widely employed in power
generation and cogeneration
applications with millions of
accumulated operating hours.
In pure power generation applications
without heat recovery, a distinction can
be made between the following
service applications:
Continuous operation with the
generator feeding into a grid
network, for which the robusttrouble free nature of the THM
series is ideal.
Island mode operation of a single
machine set, or of a power plant
consisting of several power trains.
supplying a local grid, without any
tie-in to a wide-area network.
Power supply systems used on
offshore oil production platforms
are typical examples that require
a high supply reliability.
Intermittent operation for:
1. balancing the peak load
requirements of a grid,
2. emergency cover of a supply
sector in the event that main
generation equipment fails,
3. compensation of irregular
fluctuations in load demand, i.e. to
satisfy power requirements for a
limited number of hours, e.g.
during loading operations.
For both island mode and peaking
operation, high starting reliability is an
essential prerequisite to ensure relia-
bility of supply.

Outdoor Installation
The skid option with a weatherproof
acoustic enclosure enables the THM
turbine-generator sets to be installed
outdoors without the need for
investment in a building.

The temperature of the exhaust gases
leaving the THM gas turbine are at
approx. 500C, assuming ISO
operation in open cycle.
With the THM 1304-11, approx.
22 MW (thermal) can be recovered
through heat exchange down to a
final stack temperature of 100C. This
energy can then be utilized in various
processes.
Direct drying processes (e.g.
sewage sludge) using the hot
exhaust gases can be employed,
provided that the materials in
question suffer no damage.
Alternatively, indirect drying can be
used with an intermediate drying
medium (e.g. air).
Cogeneration processes where, in
addition to electric power
production, steam or hot water is
produced in a waste heat boiler.The heat can be utilized in various
processes, e.g. paper production,
district heating etc.
Steam generated in a waste heat
boiler can be used to drive a
condensing steam turbine, thereby
producing 4 5 MW of additional
electric energy. This configuration of
gas turbine, waste heat boiler,
steam turbine and auxiliary plant
units (condensation system etc.)
forms a combined cycle (CCGT)
power plant. Based on the THM
1304-11 and a single-pressure
boiler without supplementary firing
capacity, Figure 5 shows, as anexample, the steam rate which can
be produced as a function of steam
pressure, with steam temperature
as the other selection parameter.
Similar diagrams are available for
other system configurations.

In addition to cogeneration, so-
called "trigeneration" cycles are
also possible whereby, in addition
to electric power, heat and
refrigeration energy can be supplied
from the same system. Using this
configuration, the steam generated
in the waste heat boiler can either
be used for heating purposes or for
supplying an absorption refrigera-
tion plant.
For example, a trigeneration facility
can be used to operate the heatingsystem of a building complex in
winter, and its air-conditioning
system in summer.
