摘　　要：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。In the sulfur recovery unit, the importance of tail gas incinerator is only inferior to the acid gas burner. Because the toxicity of H2S is more severe than that of SO2, many countries have ruled that sulfur-containing exhaust gas is forbidden to discharge before burned out. Whether the sulfur recovery unit is equipped with tail gas treat system, H2S and other sulfides should be oxygenized before emission. The SULSIM software is used in thermal technical calculation of tail gas incinerator. The calculation of tail gas incinerator by other software has not been described. HTRI can be used in combustion calculation and thermal equilibrium calculation of tail gas incinerator, and the calculation result of flux of fuel gas required air and flue gas all meet the design value of tail gas incinerator, which can also provide reference for design of tail gas incinerator of sulfur recovery unit.
