The rotary kiln systems of the cement industry destroy virtually completely the Ps input via fuels. Emissions are generated from organic constituents in the raw material. Benzene, toluene, ethylbenzene, xylene (BTEX) As a rule benzene, toluene, ethylbenzene and xylene are present in the exhaust gas of rotary kilns in a characteristic ratio.
The kiln connects with a material exit hood at the lower end and ducts for waste gases. This requires gastight seals at either end of the kiln. The exhaust gas may go to waste, or may enter a preheater which further exchanges heat with the entering feed. The gases must be drawn through the kiln, and the preheater if fitted, by a fan situated ...
