【摘要】 用管式沉降炉和3.5 kW煤粉燃烧试验炉对3种煤在着火、燃烧初期和燃烧过程中氮释放和NO_x转化特性进行了试验研究。燃烧初期煤中氮释放特性有显著差异；氮释放率高于当时的燃尽率；NO_x生成主要受燃烧空气量和送风方式影响。更多还原

【Abstract】 Use drop tube furnace and 3.5 kW furnace on experimental investigation of nitrogen release and conversion of the NO_x in ignition, preliminary burning and combustion process for 3 kinds of coals. The experiment proves the nitrogen release is outstanding different in preliminary burning stage, the release rate of nitrogen is greater than the burnt-out rate at that time, the production rate of the NO_x is mainly under the influence of the air quantity for the combustion and the air-blasting modes.更多还原
