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.
