Application Analysis of Desulfurization Technology in Coal Mine Boiler Equipment
In order to further explore the strategies for improving the desulfurization effect of coal mine boiler equipment,a 2×300 MW CFB steam boiler of a coal mine enterprise was taken as a research case.In response to the problem of excessive sulfur dioxide emissions from the heating boiler,the impact of calcium sulfur ratio on the utilization rate of desulfurizer,sulfur dioxide emission characteristics,and desulfurization efficiency was analyzed from the perspective of calcium sulfur ratio.Through comprehensive analysis,a reasonable calcium sulfur ratio of 3.5 was determined.Next,analyze how different limestone particle sizes affect desulfurization efficiency and determine a reasonable limestone particle size of 1 mm.Finally,actual testing was conducted based on the parameter combination,and the results showed that the optimized desulfurization effect was significantly improved.The measured concentration of sulfur dioxide decreased from 247 mg/m3 before optimization to 126 mg/m3,which can meet practical needs.
