Scope

This standard specifies the basic principles, content, accounting methods and requirements for accounting for pollution sources in the coking chemical industry. This standard is applicable to the calculation of pollution sources of new (renovated, expanded) projects and pollution sources of existing projects in the coking chemical industry. This standard is applicable to the source intensity accounting under normal and abnormal discharge conditions in the coking chemical industry, and is not applicable to the source intensity accounting under sudden leakage, fire, explosion and other accidents. This standard is applicable to the accounting of pollution sources of waste gas, waste water, noise and solid waste in production processes such as coal preparation, coking, coke processing, gas purification, coking chemical product recovery and thermal energy utilization. Coke oven types include conventional coke ovens and heat recovery coke ovens. furnace and semi-coke (blue charcoal) carbonization furnace. The pollution source intensity of boilers that implements GB13223 is calculated in accordance with HJ888; the pollution source intensity of boilers that implements GB13271 is calculated in accordance with the Boiler Pollution Source Intensity Accounting Technical Guidelines. 2. Silencers 12 to 25 for the air inlet of indoor sound sources. 20 to 35 silencers for the exhaust ports of blowers, combustion fans, etc.
