--- Added safety requirements for coke oven pushing, coal loading and dust removal (see 9.1.47);

--- Added safety requirements for anhydrous ammonia process (see 10.2.21~10.2.29);

--- Deleted the requirements related to dry quenching (see

1 Scope

China's mandatory safety specification for coking plants. A coke oven battery is one of the most hazardous installations in heavy industry, and for reasons that compound each other: it operates at over a thousand degrees continuously for decades, it produces coke oven gas that is both flammable and rich in carbon monoxide, and it releases the coal tar volatiles that made coke oven emissions one of the first recognised occupational carcinogens. The specification covers the fire and explosion controls on the gas system, where the danger is a mixture reaching the explosive range inside a main or a holder, the carbon monoxide detection and rescue arrangements, the by-product plant with its benzene and ammonia, the quenching operations, and the protection of the workers on the oven top who stand in the emissions. It applies to the design, construction and operation of coking plants.

This document stipulates the overall requirements for safe production of coking enterprises, plant layout, buildings (structures), equipment and facilities, processes and maintenance, etc. Technical requirements. This document is applicable to the design of new construction, reconstruction and expansion projects of coking enterprises, as well as the production, inspection, maintenance and safety management of the enterprises.
