The main sources of dust and gas emission are processing and storage of coal, coking of coal and its quenching. Coke dust is generated when coke is fed from oven chambers, transported, sifted, fragmented and shipped; when dry quenching plants are used, such dust is generated from fore-chambers and smoke pipe bleeders.

The speed of particles is reduced by intensive suction of the crusher chambers through a maze (metallic parts entrained by air stream fall back into the crusher). Dust grain size of 0.05 to 0.8 mm is separated in a cyclone; the fractions of 0.05 mm are collected on a filter tissue and both fractions fall through the rotary feeders to the big-bags.
