Design and operation of a large utility coal handling system in a cold weather climate
This article reviews and highlights the primary points of benefit in considering the design of a new large utility coal handling system in a cold weather climate. The primary conclusions drawn are: material properties, mining methods and coal preparation used at individual sources all have a significant impact on the ability of a handling system to move coal; no single equipment or operating procedure modification provided an answer to the coal handling problems which were encountered during the first winter; of the modifications made, the one with the largest impact was the formulation of a coal pile management plan. The implementation of this plan minimized wintertime reclaiming problems and significantly reduced the need for costly treatment; coal handling systems in cold weather climates should be enclosed and minimally heated; when the use of a stacker/reclaimer is considered for a cold weather climate, a commitment must be made to include design options which help the machine deal with cold weather and provide the maintenance/operating support necessary to optimize reliability during winter; a high priority preventive maintenance program is a necessity during the winter; and the use of a thaw shed and the reclaiming of warm coal have proven to be much more effective than the use of freeze conditioning agents.
