摘要
设计了一套适用于300 MW级CFB锅炉干态氨法SNCR烟气脱硝装置,其处理烟气量为100万Nm^3/h,NO_x含量为390 mg/Nm^3,系统脱硝效率不低于50%,烟气中NO_x排放浓度≤195 mg/Nm^3。该系统经济性分析结果表明,经济性受氨水市场价格影响较大,在当前氨水价格及脱硝电价补贴条件下,该系统总投资约400万元,年运行费用约1 117.9万元,年综合收益约667.6万元。
A dry state-ammonia SNCR flue gas denitrification device applied to 300 MW CFB boiler is designed,this device can handle 1 million Nm^3/ h flue gas and 390 mg / Nm^3 NO_x. Denitration efficiency is more than 50%,NO_x emission concentration in flue gas is less than 195 mg / Nm^3. Economic analysis results show that the system economy are greatly influenced by market price of ammonia.Total investment of the system is about 4 million yuan,annual operating cost is about 11. 179 million yuan,annual comprehensive income about 6. 676 million yuan.
