Presented at the American Coal Council PRB Coal Use Seminar, Detroit MI, June 2526, 2003 OPERATIONAL OPTIONS FOR DUST CONTROL Bernard H. Schonbach, Principal, Manager Mechanical Engineering CDG Engineers The electric utility industry continues to face the challenge of controlling fugitive dust problems.
Because Powder River Basin (PRB) coal is smaller, more friable, and contains more fine particulates than bituminous coal, controlling the fugitive dust generated as PRB coal moves from bunker to ...
This invariably results in a cloud of airborne dust and increases housekeeping. The solutions to this problem and for other conveyor transfers is solved best by the following two methods: METHOD 1: Pneumatic Transfer. METHOD 2: Agglomeration. back to AirCure''s approach to PRB Coal Dust Collection

Classification of coal based on volatile matter and cooking power of clean material Sponsored Links Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.
While containing less sulfur, PRB coal contains more water, generates less heat and burns less efficiently than the type of coal it replaced. In fact, though overall emissions have been reduced, the plant now requires more throughput to ensure the same generating capacity. Even more vexing, due to several of the inherent properties of PRB coal, it is prone to sudden, spontaneous combustion.

This chapter provides information on activated carbon injection (ACI) into flue gas, factors limiting the effectiveness of ACI, and balanceofplant considerations.
The Powder River Basin is the largest coal mining region in the United States, but most of the coal is buried too deeply to be economically accessible. The Powder River Basin coal beds are shaped like elongated bowls and as mines expand from east to west in the Powder River Basin, they will be going "down the sides of the bowl".
