介绍了灰粘聚循环流化床粉煤气化的原理、工艺流程及工艺特点。
The principle, process and the characteristics of coal powder gasification by the ash agglomeration circulating fluidized bed are introduced.
利用循环流化床技术气化廉价的粉煤，通过合理组织流程，可降低尿素生产成本。
The circulating fluid bed technology is used to gasify cheap pulverized coal, and by rational organization of the process flow the production cost of urea can be decreased.
在分选过程中，流化床内的粉煤将不断积聚，从而导致床层密度的降低。
In the separation process the fine coal in fluidized bed will be continuously accumulated, thus inevitably reducing the density of the bed.
