Japan depends on imports for most energy resources. To obtain stable supplies of energy and protect the global environment, not only high-efficiency use of existing fossil-based power generation but unused resources’ reexamination, waste material utilization, and highly effective use of such resources will be important. Discoverable reserves of bituminous raw materials are several times larger than that of crude (figure 1). In Japan, power-generation infrastructures are equipped in incineration of around 60% of the waste and the thermal-efficiency is only around 10% on the average. When introducing the high-efficiency technologies into waste incinerators, its electricity corresponds to around 4% power demand of the electric power industry or one second of hydroelectric generation. Developments of integrated gasification combined cycle (IGCC) continue worldwide, and such technologies enable high-efficiency generation from various quality resources. This paper reviews the trends of IGCCs’ developments worldwide and outlines combustion technologies of the high temperature gas turbine for IGCC in Japan.
