Igneous electricity flue gas takes off saltpetre system whether achieve take off saltpetre rate and low ammonia gas high to escape rate, depend on greatly the flue gas is medium nitrogen oxide before entering saltpetre reactor and reducer ammonia gas blend even degree and flue gas speed to distributing.

梗概： 火电烟气脱硝系统能否达到高脱硝率和低氨气逃逸率，很大程度上取决于进入脱硝反应器之前烟气中的氮氧化物和还原剂氨气混合均匀程度和烟气速度分布。

The results show that biomass owns higher NO removal efficiency than pulverized coal. NO removal efficiency of three kinds of fuels increases by different extent through the increase of reburn fuel fraction and the decrease of the excess air ratio. NO removal efficiency of corn straw is the most efficient; rice husk is medium, pulverized bituminous coal is the lowest. Within the certain reburn resident time (650 ms), NO removal efficiency increases quickly with the resident time.

研究表明：生物质脱硝能力明显高于煤粉，提高再然比例及减小过量空气系数，3种燃料的脱硝率有不同程度的提高，其中秸秆脱硝率最高，稻壳中等，煤粉最低；在一定的再燃停留时间内(650 ms)，延长停留时间，脱硝率增加，超过这一停留时间，脱硝率增加缓慢。
