Air & Climate - Washington State Department of Ecology

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

Pulverized Coal Pipe Testing and Balancing

Also, a balanced 'clean air flow' distribution does not necessarily result in a balanced 'dirty air' or 'coal flow' distribution amongst the discharge pipes of a mill. The focus needs to be on dirty airflow and coal flow balance measurements. The relative flow distribution between burner pipes is assessed by
