空気吹きIGCCの開発状況

抄録

From the viewpoint of energy security and global warming issues, highly efficient coal utilization system, such as the integrated coal gasification combined cycle (IGCC) power systems are increasing their market size. As one of the leading companies in the field of IGCC, MHPS and MHI are now in a position to build up market share. With an integration of two-stage entrained flow air-blown coal gasifier, the IGCC will achieve the highest net plant efficiency by using air as the gasification agent, and the F or G-class high temperature combustion turbine for power generation market. This paper includes discussions on the latest status of the 250MW Nakoso IGCC commercial plant and overview of 500 MW class plant. This paper will also discuss about our latest approach for feed stock flexibility (biomass, petroleum coke…etc).
