CCS is regarded as a method to reduce CO2 emission. Huge energy is required to capture CO2 from exhaust gas of thermal power station, thermal efficiency decreases and cost of electricity increases. The oxy-fuel IGCC system is under development to solve this problem, by Central Research Institute of Electric Power Industry (CRIEPI), Mitsubishi Heavy Industries Co. ltd. and Mitsubishi Hitachi Power Systems Co. ltd. as NEDO (New Energy and Industrial Technology Development Organization) funded project. This system is composed of O2/CO2 blown gasifier and semi-closed cycle gas turbine, and the system is expected to keep high efficiency more than 42% at HHV after CO2 capture. CRIEPI runs several experimental researches and numerical simulations. This report is to update net efficiency estimation data depending on results acquired by 3-Dimensioanl numerical simulation on coal gasifier including gasification and combustion reaction and particle behavior, and to estimate impact of CO2 purification on efficiency.
