Abstract:

Environmental problems during coking production of Masteel coke oven battery are described.Dust is collected through the methods of coke screening for battery No.1~4,optimizing CDQ de-dusting,technical improvement on pushing de-dusting of 7.63m coke oven battery,and construction of 3 stationary bag house stations for charging and pushing of battery No.5~6.In addition,measures such as strengthening the maintenance and management of aged ovens,using new glazed refractory and improvement on knife edge can effectively minimize the leakage of intermittent smoke.
