摘要
本文介绍了在某热电厂5×75t/h锅炉湿法脱硫出口烟气有色烟羽治理技术"低温省煤器+喷淋冷凝器+板换-热泵机组",使烟囱入口烟气温度非采暖季降至48℃以下;采暖季降至45℃以下,有色烟羽治理同时达到对烟气余热深度回收目的;烟囱出口粉尘排放值低于5mg/Nm^3。
This paper introduces the treatment technology of non-ferrous plume of flue gas at the outlet of 5×75t/h wet FGD boiler in a thermal power plant,which is"low temperature economizer+spray condenser+plate exchange heat pump unit",which can reduce the flue gas temperature at the inlet of chimney to below 48℃in non heating season,below 45℃in heating season,the non-ferrous plume treatment can achieve the purpose of deep recovery of flue gas waste heat at the same time,and the dust emission value at the outlet of chimney is lower than 5mg/Nm^3.
