摘要
在自行设计的气化焚烧炉内对典型城市固体废弃物与煤混合物料进行气化焚烧试验,分别采用空气、氧气及水蒸气作为气化介质。分析了物料、气化温度、气化剂及气化剂流量、燃烧器的工作状态等影响因素发生变化时,气化燃料焚烧处理过程烟气中NOx、SO2的排放特性。结果表明,经二次焚烧处理气化燃料后,烟气中NOx、SO2的排放浓度比较低;当燃烧器工作时,NOx最大排放浓度为184mg/m3,SO2最大排放浓度为57mg/m3,远远低于国家规定值,焚烧减污效果明显。
The gassifying incineration of municipal solid waste(MSW) and coal mixture has been carried out in a selfdesigned gassifying incinerator, and taking air, oxygen, and steam as gassifying medium respectively. The NO_x and SO_2 emission behavior in flue gas during period of gassifying incineration treatment under variation of affecting factors, such as materials, gassifying temperature, gassifying agent, and operation state of the burners etc., has been analysed. Results show that the concentration of NO_x and SO_2 in the flue gas is comparatively lower after secondary incineration treatment of the gassifying fuel. Under operation of the burners, the max. emission concentration of NO_x to be 184 mg/m3, the max. emission concentration of SO_2 to be 57 mg/m3, they are far lower than defined value by the state, the effectiveness of incineration to decrease pollutan emission being remarkable.
