Thermal Tests of LMS100 Gas-Turbine Units at the Dzhubga Thermal Power Plant

Test results at different loads and ambient temperatures for LMS100 PB gas-turbine units at the Dzhubga thermal power plant are discussed. The performance indicators for these gas turbine units and their turbine equipment, combustion chambers, and air cooling systems are determined. The gas-turbine units produce the design power (normally about 90 MW, and up to 95 – 99 MW when necessary) with a gross efficiency of 42.3 – 42.7% with moderate (no more than 20 – 35 mg/m³) atmospheric emissions of nitrogen oxides (under normal conditions). The differences in the performance of individual components of the gas-turbine units are within the limits of error in the measurements.
