Advanced IGCC was planned by using exergy-recuperation concept. Advanced IGCC achieve high efficiency by the gas purification at high temperature and the autothermal reaction in the gasifier. The increment of the efficiency IGCC to the standard case is about 4% by applying autothermal reaction in the gasifier. This system requires the extra heat supply in order to hold the autothermal reaction condition in the gasifier. Therefore the increment of the gross efficiency by applying autothermal reaction is only 1% (HHV). The gross thermal efficiency of 1500 degree C class Advanced IGCC is 53.3%(HHV) i.e. 5.3% (HHV) higher than standard case. When turbine inlet temperature increase from 1500 degree C to 1700 degree C, the gross thermal efficiency increases from 53.3% to over 57% (HHV) and it is about 59% (HHV) when the adiabatic efficiency of compressor and high temperature turbine increase 5points.
