Abstract

Disclosed is a multi-burner gasification reactor for gasification of slurry or pulverized hydrocarbon feed materials and industry applications thereof. Burners are disposed on the periphery or top of a gasification reactor vessel, wherein the side burners are at a small downward angle relative to the horizontal plane, which can prolong the life of refractory bricks. The operating pressure of the gasification reactor is 0.1˜12 MPa, and the operating temperature thereof is 1350° C.˜1700° C. The gasification reactor is applicable to a hot-wall lining as well as a cold-wall lining. The notable advantages of the gasification reactor are carbon conversion is high and can reach 99%, and the effective gas content is high; specific coal consumption and specific oxygen consumption are low; and it is applicable to a large coal gasification plant that processes above 3000 tons of coal per day.
