IGCC achieve high efficiency energy conversion from coal to electricity. However its efficiency is below 50% [HHV]. To achieve higher efficiency, Advanced IGCC was planned by using exergy-recuperation concept. Advanced IGCC requires many breakthroughs in technology. Advanced IGCC achieve high efficiency by using the heat of reformed gas and the application of the autothermal reaction in the gasifier. Authors try parametric study of Advanced IGCC to figure out the desirable consists of Advanced IGCC. The performance of Advanced IGCC depends on coal, gasifier condition, configuration of components, etc. The heat value of the supplied coal is 667MW [HHV]. Foreign subbituminous coal is selected as standard fuel. The adiabatic efficiencies of the compressor, the gas turbine, steam turbine and condensing turbine at standard condition were defined so that the efficiency of IGCC with 1500 °C class gas turbine is 48% [HHV] with high performance gasifier. The efficiency of IGCC reaches to 52% [HHV] 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 net efficiency of this system is about 44% [HHV]. The net efficiency of the advanced IGCC is 48% [HHV]. On the other hand, 1700 °C class advanced IGCC can achieve 51% [HHV] net efficiency and its gas turbine exhaust high temperature heat to hold autothermal reaction condition. Increase of the adiabatic efficiencies of the compressor and the gas turbine enables the high efficiency of the advanced IGCC. If the adiabatic efficiency of compressor reaches to 87% and adiabatic efficiency of the gas turbine reaches to 92%, 1700 °C class advanced IGCC has the potential of over 60% [HHV].
