煤矸石在流化床燃烧器中着火特性的试验研究

Experimental Study on Ignition of Coal Gangue in A Fluidized Bed Combustor

介绍在小型流化床燃烧器中进行的煤矸石着火过程试验研究。以沸腾着火指数为指标定量描述了不同粒度煤矸石在不同床温下的着火特性，寻找了最低着火温度，为该种煤矸石流化床燃烧器提供了设计依据。

By taking fluidized fire index FI as scale,the paper decribes the ignition behavior of the coal gangue in different particle sizes and bed temperatures through experimental study. The lowest ignition temperature thus obtained can be served as basis in designing fluidized bed combustor by using the same kind of coal gangue as fuel.
