Replacing Dust Collectors with Foam at a PRB Coal Mine

摘要

A Powder River Basin coal mine in Montana needed to upgrade or eliminate the overland bag house dust collectors to meet their safety, production, and fugitive dust suppression goals. An in-house study determined that the cost of a dust collector upgrade would yield only a slight increase in production, and would not address their safety and environmental objectives. A better solution was needed. The coal mine determined that they could eliminate the need for overland dust collectors, reduce fugitive dust emissions, reduce dust handling, and have a safer operation, by replacing the dust collectors with a comprehensive foam dust control system.
