燃煤机组锅炉低氮燃烧器改造运行调整探讨

Discussion on Reformation and Adjustment of Low-nitrogen Burner in Coal-fired Boiler

研究表明,对于反应器出口氮氧化物的排放量以及氧含量存在最适范围,烟气再循环开度与二次风入射角度会对燃料产生显著影响,当后燃严重时甚至会使非催化还原反应效率降低,甚至处于失效状态.

Studies have shown that there is an optimum range for the emission of nitrogen oxides at the outlet of the reactor and the oxygen content. The recirculation opening of the flue gas and the angle of incidence of the secondary air will have a significant impact on the fuel, even when the post-combustion is severe. The non-catalytic reduction reaction is reduced in efficiency and even in a failed state.
