It is expected that Integrated Coal Gasification Combined Cycle Power Generation Technology (IGCC) is one of the most important key technologies to get over the vulnerability of energy supply for the future because of its higher thermal efficiency, high environmental acceptability and operability.
In comparison with conventional coal firing plant, IGCC includes such peculiar tech-nologies as coal gasification, gas clean up system and gas turbine. In Japan, according to the “Sunshine Project” of which the development program for new energy, we aimed at higher thermal efficiency and have developed pressurized entrained flow gasifier, hot-dry type gas clean up system and gas turbine for low carolific gas. 200 ton per day processing pilot plant was started in gasification operation in June of this year.
Also much interest and development are now going on for the IGCC technologies in many countries in the world.
