The sound levels decrease significantly with increasing distance from the screens, indi­ cating that the screens dominate the overall Aweighted sound level in this area of the preparation plant.

Coke Production US EPA

Coke Production General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

Improving Coal Pulverizer Performance and Reliability

type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw

pulverized, and oiled for proper bulk density control. The blended coal is charged into a number of slot type ovens wherein each oven shares a common heating flue with the adjacent oven. Coal is carbonized in a reducing atmosphere and the offgas is collected and sent to the byproduct plant where various byproducts are recovered. Hence, this
