Ordos ammonia desulfurization ultra low emission project
Two 130t / h circulating fluidized bed boilers in thermal power station of Northwest energy and Chemical Group Co., Ltd. are equipped with flue gas desulfurization (ammonia process, two boilers and one tower) system. The ammonia desulfurization device adopts empty tower spray type, which can not produce ammonium sulfate products. The flue gas outlet has serious tailing and the dust content at the outlet is not up to standard.
This time, Shandong Mingsheng Environmental Protection Technology Co., Ltd. upgraded the device, realized the normal discharge of the desulfurization device, the flue gas tailing situation was significantly improved, and the system can stably meet the emission requirements. Under various working conditions, the flue gas concentration of ammonia is less than or equal to 50 mg three 、SO two ≤50mg/Nm three The utilization rate of ammonia (recovery) is not less than 98%, and ammonia escape is not more than 7.6mg/nm3.
