In terms of ash agglomerating fluidized bed fine coal gasification process, the fluid dynamics, jet behavior and bubble property are reviewed in this paper.

以灰熔聚流化床粉煤气化工艺为背景，概括了射流床内床层动力学、射流特性以及密相中的气泡性质的研究进展。

In the separation process the fine coal in fluidized bed will be continuously accumulated, thus inevitably reducing the density of the bed.

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。

Briefly expound the significance of fine coal briquetting in using coal resources, and introduce the concept, task and process classification of it.

本文对粉煤成型在充分利用煤炭资源方面的意义做了概括性的阐述，对粉煤成型的概念、任务及工艺分类等方面也做了简要的介绍。

All of which is fine and dandy except that, if rigged to the average coal-fired power station, this process might use a quarter of the energy the plant produces.
