The article educes a relation about charcoal percent conversion and running temperature, gas caloricity, gasification efficiency, system efficiency by three programmes's calculation. So charcoal percent conversion has important influence on system's operation. And It is confirmed that air partial gasificat ion combined cycle generation system is a high efficiency, low pollution, techno logy simpleness, low investment, short periodicity generation system by comparis on with else combined cycle generation systems of different gasification mode.
