摘要: 结合火力发电厂近年来的实际运行煤质的变化情况,以实例说明了当煤质变化时,不能只考虑硫分的变化,还要综合考虑煤质低位发热量对二氧化硫质量浓度的影响。最后提出了当烟气参数偏离设计参数时,运行中应注意的问题。

Abstract: Combining with the variation of coal actually fired in thermal power plant during last years, it is explained by example that when the coal quality varied, not only the variation of sulfur content must be considered, but also the influence of the low heat productivity of the coal on the mass concentration of SO2 must be taken into account. At last, some problems needing attention in operation while the parameters of flue gas diverge from the designed values were put forward.

Key words: desulphurization equipment, sulfur content of coal, heat productivity of coal, operation mode
