摘　　要：工业锅炉燃烧产生的烟气中主要危害气体之一为SO_(2),在锅炉尾部除尘后至烟囱的烟道加装脱硫设备,采用氧化钙或氧化镁两种药剂进行烟气脱硫,是目前控制SO_(2)和酸雨污染最普遍也是最成熟的两种技术手段。熟知工业锅炉利用氧化钙法和氧化镁法烟气脱硫的原理,并以燃用神府地区发热量为6000 kcal/kg、含硫量为0.4%烟煤的29 MW工业煤粉锅炉为例,计算分析选用两种不同脱硫技术的经济性,选择合理的烟气脱硫方式,提高锅炉经济效益。SO_(2) is one of the main harmful gases in the flue gas produced by industrial boiler combustion.It is the most common and mature technology to control SO_(2) and acid rain pollution by installing desulfurization equipment in the flue gas from the tail of the boiler to the chimney and using calcium oxide or magnesium oxide as desulfurization agents.Familiar with the principle of flue gas desulfurization by calcium oxide method and magnesium oxide method in industrial boilers,and taking 29 MW industrial pulverized coal boilers with 6000 kcal/kg and 0.4%bituminous coal in Shenfu area as an example,the economy of two different desulfurization technologies is calculated and analyzed,and reasonable flue gas desulfurization methods are selected to improve the economic benefits of boilers.
