The Reasons and Treatments of the Common Pressureout Problem in Fixed Bed Gasification
XIANG Hong
(Hubei Newyangfeng Fertilizer Stock Co., Ltd., Jingmen Hubei 448150，China)
Abstract: Take the actual examples to explain the pressureout reasons in the fixed bed gasification unit，the reasons include the pipeline equipment fouling increasing resistance，the water seal plugging of scrubber and gas holder imports increasing resistance，low negative pressure in latent heat system increasing air blow gas resistance，and valves slow action or non-action caused by low oil pressure or pressure sudden drop increasing resistance.Take the right measures to eliminate abnormal increased resistance in the unit to maintain normal operation of the gasifier.
Key words: water seal；dust container；coke layer；hydraulic cylinder；grate；resistance；valve
