尾气焚烧炉是硫磺回收装置重要性仅次于酸性气燃烧炉的重要设备,由于H2S的毒性远比SO_2严重,大多数国家的法律规定,含硫尾气未经焚烧不允许排放,因而无论硫磺回收是否设有尾气处理系统,尾气排放前均应通过焚烧将尾气中的H_2S和其它硫化物全部氧化成SO_2后排放。尾气焚烧炉的热工计算大多在硫磺回收装置设计时由SULSIM软件进行计算,目前尚未见采用其它软件进行尾气焚烧炉热工计算的报道。通过HTRI进行尾气焚烧炉的燃烧计算和热平衡计算,计算得到的燃料气量、所需空气量、烟气量较好的符合尾气焚烧炉原设计数据为硫磺回收尾气焚烧炉设计提供了借鉴。
Exhaust gas incinerator is the second most important equipment of sulfur recovery unit in sour gas combustion furnace. Because of the toxicity of H2S is far more serious than that of SO2, most countries’ laws stipulate that sulfur-free exhaust gas will not be allowed to be released without incineration, so regardless of sulfur recovery Whether there is an exhaust gas treatment system, the tail gas emissions should be incinerated by the tail gas H_2S and other sulfide all oxidized to SO_2 emissions. Thermal calculation of exhaust gas incinerators are mostly calculated by SULSIM software when the sulfur recovery unit is designed. There is no report about the thermal calculation of exhaust gas incinerators using other software at present. Through the HTRI combustion calculation and heat balance calculation of the exhaust incinerator, the calculation of the fuel gas volume, the required air volume, and the flue gas volume are in good agreement with the original design data of the exhaust incinerator, which provides a reference for the design of the sulfur recovery exhaust incinerator.
