摘要
A method of operation of an Advanced Cheng Cycle heat engine comprising: (a) initializing start conditions in the gas turbine engine and the heat recovery steam generator with the control system; (b) setting the control valve means for idle flow condition of the heat engine; (c) pressurizing the drum with the compressed gas source to approximately the desired operating pressure of the heat recovery steam generator; (d) starting the gas turbine engine from idle to full load as limited by maximum allowed turbine inlet temperature; and (e) throttling second working fluid flow rate with the control valve means and shutting off the compressed gas source, after the sensor system indicates that heat recovery steam generator pressure is higher than compressor discharge pressure. Throttling is performed in accordance with the following operating parameters: (i) second working fluid temperature as injected into the turbine less than or substantially equal to first working fluid temperature at the compressor outlet, and (ii) maximization of heat recovery from the turbine exhaust for a given peak efficiency mixture ratio of second working fluid to first working fluid in the turbine, so that heat recovery exchanger pinch temperature is minimized.
