Analysis of the causes for powder carrying in Lurgi gasfier and optimization measures
Lurgi pressure gasification processis is an self-heating,counter-current contact,continuous gasification,solid state slagging process.Due to its mature technology,wide applicability of coal types and large production capacity,it is widely used and is currently the coal gasification technology with a large number of plants built in the world.Because the CH4 content in the crude gas is as high as 12%to 14%,and the by-production of heavy aromatics,polyhydrocarbons,light hydrocarbons,mixed phenols,etc.,the investment is low,and the comprehensive cost of synthesized methane is relatively low,so at present,coal to natural gas enterprises have been put into operation in China have usually adopted this gasification process.However,in the actual operation process,due to the change of feedstock coal quality,gasifier load and operating conditions fluctuations and other factors,resulting in the gasifier with powder problems occur from time to time.This paper analyzes the causes for powder in the gasifier of Yili Xintian Coal Chemical Co.,Ltd.and discussed how to effectively reduce the gasifier with powder and the impact of the powder on the related system.
