| 摘 要： | Coal gasification is not only the foundation ofcoal clean conversion, but also a key technique of coalclean conversion. The application of coal gasificationtechnology in China has a history of about 120 a.Three typical gasification technologies i.e. fixed-bedgasifier, fluidized-bed gasifier and entrained-flow bedgasifier are all applied in China. More than 80 milliontons of raw coal is used for gasification in China everyyear. Coal gas is mainly used as industrial fuel,chemical synthesis mat…

| Abstract: | Introduced the application and development status of coal gasification tech- nology in China. The most widely used coal gasification technology in China is the at- mospheric fixed-bed gasifier, its total number is about 9 000. About 30 pressurized fixed-bed gasifiers are in operation, and more than 10 atmospheric fluidized-bed gasifi- ers were used. There are 13 Texaco entrained-flow bed gasifiers are under operation, 10 Texaco and 11 Shell gasifiers that are being installed or imported. About 10 under- ground gasifiers are under running now. The present R&D of coal gasification technolo- gies are to improve the operation and controlling level of fixed-bed gasification technol- ogy, and developing or demonstration of fluidized-bed and entrained-flow bed gasifiers. |
