超净排放中烟冷器出口烟温控制优化措施

Smoke Temperature Control Optimization for Smoke Cooler Outlet in Ultraclean Discharge

分析了超净排放设施投用后烟冷器和烟热器运行情况,同时结合空预器后烟气酸露点试验数据,分析了烟热器后降烟温运行的可能性。通过实际降烟温运行,验证了新运行方式下的设备安全性和机组经济性,最终实现满足超净排放要求的同时实现机组低能耗超净运行。

This paper analyzes the operation state of smoke cooler and heater with the ultraclean discharge facil- ities put in service, and combining with the flue gas acid dew point test data for the air preheater, it also analy- zes the possibility of reducing smoke temperature of smoke heater. The actual smoke temperature reducing op- eration has validated the equipment security and efficiency under the new operation mode for the purpose of re- alizing ultraclean discharge and achieving the unit low-power ultraclean operation.
