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.

Abstract: A two-stage gasification apparatus coupled with heat recovery and washing includes a columnar shell (7), an entrained flow gasification chamber (1), a fixed bed gasification chamber (18), a waste heat boiler (19) and a gas cooling-washing chamber (14) set coaxially from top to bottom inside the columnar shell (7). Process nozzle chambers (3) are set at a sidewall and/or a top of the entrained flow gasification chamber (1), and process nozzles (2) are set in a nozzle chambers (3). A feed-in lock hopper (25) is set and a fixed bed gasification chamber (18). An eccentric grate (10) is set in the middle of a lower part of the fixed bed gasification chamber (18), and the grate is connected with an ash-pan (11), which is conjoined with a motor (36) via transmission mechanism. An inverse cone (22) is erected at an upper part of a cooling-washing chamber (14).
