山西晋城加压灰熔聚（Pressurized ash agglomeration in Shanxi, Jincheng） Chinese Academy of Sciences, Shanxi Institute of coal chemistry of ash agglomerating fluidized bed coal gasification technology has been developed for more than 20 years, the completion of large-scale low middle test in 1990, 2001 completed large-scale industrial demonstration operation, attracted industry attention and concern. The scale of the technology, but the grade and chemical synthesis or future power requirements there is a gap between the pressure, so nearly ten years to carry out the research and development of pressurized coal gasification process, and on 2004 in Shanxi province development and Reform Commission, with the support of Shanxi Jincheng Anthracite mining group co founded the Shanxi province coal gasification Engineering Research center. In the 2005~2006 year, a large scale pressurized ash fired Fluidized Bed Coal Gasification semi industrial plant has been designed and established to obtain industrial amplification data and experience. Completed construction in early 2007, after six months of equipment debugging and improvement, in December 2007 completed a long period of 1 MPa pressure test, and achieved good data and accumulated experience in operation. In this paper, the research and development of the technology is introduced. ]%?: K0 Y) L R p$V 1 ash melt fluidized bed pulverized coal gasification technology research and development process 8, i%, _2,}1, N2, B Coal gasification technology is widely used in many fields such as chemical industry, metallurgy, machinery, city gas and so on. In view of the current development trend of coal gasification technology at home and abroad, it is the development direction of coal gasification to scale, pressurize, adapt to various kinds of pulverized coal, low pollution and easy to purify. The new developed gasifier in foreign countries adopts pressurized gasification process, which has the advantages of high gasification strength, large am
