METHOD OF OPERATION OF INDUSTRIAL GAS TURBINE FOR OPTIMAL PERFORMANCE

摘要

ISO date (ISO-Day) the behavior of the gas turbine is provided for the optimization of the rated capacity . The invention is realized by setting the operating limit line, so that ISO full load performance is maximized, the nominal operating line equal to or slightly less . Thus, the size of the turbine nozzle throat area of the first stage is at base load and pressure ratio and firing temperature without further inlet bleed heat , the compressor is set to operate within the operating limits of the ISO day . If ambient conditions change , the level of inlet bleed heat and ignition temperature is controlled , the inlet guide vane angle is set , whereby the nominal operating line is the same as or slightly lower operating limit line .
