Lime Kiln Flue Gas Purification Project of Yong Yang Special Steel with CIEE as the General Contractor was put into production
On February 28, the Lime Kiln Flue Gas Purification Project of Hebei Yong Yang Special Steel Group Co., Ltd. (Yong Yang Special Steel) with CIEE of CIE as the General Contractor was successfully put into operation. This project further enriches the engineering achievement of CIE in the field of flue gas treatment.
SDS dry desulfurization system + bag filter dust removal system + SCR low-temperature denitration system are adopted for this project for comprehensive treatment of flue gas generated from the lime kiln. In the process of project construction, CIEE combines the heat exchanger with the heating furnace to stabilize the operating temperature of flue gas in view of the low temperature and large fluctuation of flue gas at the tail of the lime kiln, so as to highly match with the control system and realize 100% synchronous operation with the lime kiln system.
After the project is put into operation, the emission concentration of sulfur dioxide is less than 25 mg/Nm3, and the emission concentration of nitrogen oxides is less than 100 mg/Nm3, which are far lower than the national standards for tail gas emission of lime kilns. This will effectively improve the flue gas emission quality of lime kilns of Yong Yang Special Steel and has good environmental and social benefits.
