For major users of natural gas whose consumption of gas remains constant on annual average, it may be economical to recover pressure energy in a power recovery turbine instead of destroying it by throttling the gas line pressure to the level of the supply system.

Dortmunder Stadtwerke AG, a municipal power and transport utility at the eastern end of the Ruhr engaged RWTUV to provide consultancy and inspection services for the commissioning of such an installation and to conduct performance tests on all machine components.

The special features of the control behaviour of the installation during flow-rate-oriented operation of the turbine are to be dealt with in this paper. This will be done from the point of view of a throttle-loss-free flow, as far as achievable, into the nozzle groups through the turbine inlet valves. The features of control behaviour during startup and in the case of load changes with regard to heat supply using unit cogeneration plant modules will also be looked at.

Furthermore a report will be given on the special features of the performance test.
