Abstract
Based on the analysis of sulfur balance in gas before and after coal gas combustion, the process scheme of flue gas treatment for reheating furnace of steel rolling was compared and selected according to the actual situation of ultra-low emission treatment of furnace gas in Guangdong Zhongnan Iron & Steel Co., Ltd. . The most economical and simple treatment process is selected, and the better effect is obtained. This method can be used for reference by other steel plants.
