以脱硫添加剂应对燃煤火电厂高硫煤的问题

摘要

The designed coal sulfur content of the power plant is 0.74%, and the desulfurization efficiency is 90%, when the PH value of the slurry maintains more than 5.8,the actual maximum concentration that can be coped is 2600mg/m3, equivalent to 1%sulfur content. By using the desulfurization additive, the maximum concentration can be coped is raised to 3500 mg/m3,while the PH of the slurry maintains 5.5 and the desulfurization efficiency is more than 90%, equivalent to 1.35%sulfur content, that effectively solves the problem of high-sulfur coal using among the coal-fired power plants, and also improves the economic benefit.%我司设计入炉煤种硫份为0.74%，脱硫效率90%，浆液pH值维持5.8以上时脱硫系统SO2实际最大处理能力为2600 mg/m3，折合煤质含硫1%，通过采用脱硫添加剂，在保证脱硫效率大于90%，浆液运行pH值5.5的前提下，脱硫系统的SO2实际处理能力提高到3500 mg/m3，折合煤质含硫1.35%，有效解决了火电厂高硫煤的问题，提高了电厂的经济效益。
