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.

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.
