STUDY OF INFLUENCE DEGREE OF GAS PUMPING UNIT OUTPUT PARAMETERS ON POLLUTANT EMISSION

Gas turbine plants, as well as all types of gas-using equipment, have a long service life, during which, along with the operational performance deterioration, pollutant emissions are expected to change. To take this factor into account, when developing algorithms for determining pollutant emissions from gas pumping units based on operational parameters, an analysis of changes in NOx and COx emissions (nitrogen oxides and carbon oxides) when the output parameters of the gas pumping unit deviates from the nominal ones has been carried out. The impact of operating time, repairs of the drive motor, flushing of the AL-31ST flow section was investigated. Additional tests to simulate the reduction in the available power of the unit due to a decrease in the efficiency of the axial compressor, which made it possible to quantify the impact of the deterioration in the technical condition of the gas turbine plant on NOx and COx emission were carried out.
