A102 加圧 CPC 石炭ガス化技術の開発(続報)

抄録

Pressurized Coal Partial Combustor (PCPC) is the original gasifire of KHI which consists of a precombustor and a spiral flow slugging combustor. We have conducted 25t/h PCPC pilot test operated at 2.0MPa since 1996. Through the pilot test, such as air-blown two-stage gasification, oxygen-enriched one-stage gasification, we have achieved the target value of gasification performance. And we have obtained various data of gasification about concerning a characteristic of trace elements emission, a relationship between gasification mode and char properties, a scale up characteristic of facilities and so on. After accomplishing the object, we finished all tests in June 1999 successfully. This paper describes test results of a 25t/d pilot plant.
