Coal Drying Improves Performance and Reduces Emissions

2017-9-6 · The approach to lignite drying described in this paper is based on using waste heat from the main condenser to heat the air used for coal drying. The coal drying air is heated in the water-to-air heat exchanger to approximately 110oF and is then forced through a bed of coal to remove a portion of fuel moisture. The coal drying effectiveness depends on parameters such as the flow rate and temperature of drying air, type of the coal bed (fixed or fluidized), coal size, residence time, and initial coal moisture content. Additional work and analyses are needed to size coal driers and determine tradeoffs between the different drier
