摘　　要：介绍了25 000 m^3/h级循环流化床低阶粉煤气化的工业示范装置和运行操作流程。试验研究结果表明,工业示范装置在设计负荷91.2%左右连续稳定运行440 h,中试期间,煤气的产量和成分性质稳定,煤气热值为4.41 MJ/m^3~4.83 MJ/m^3,作为工业燃气,可满足工业生产需要,气化过程(约300 h)达到并超过了168 h工业示范验收标准。This paper presents the industrial demonstration unit and the operation process flow on gasification of low- rank pulverized coal in circulating fluidized bed which can produce 25 000 m3/h of coal gas. It can be shown from the results that the gasifier is operated continuously and stably for about 440 h at 91.2% of its design capacity under the industrial demonstration conditions. During the whole operation, the gas output volume and composition property are stable, with gas heating value of 4.41 MJ/m3--4.83 MJ/m3. It can be used for industrial production as fuel gas. The gasification process （300 h） reaches 168 h industrial demonstration equipment acceptance criteria.
