Coal Drying Improves Performance and Reduces Emissions

2017-9-6 · There are many effects of fuel moisture on unit operation, performance and emissions. Its complexity can be appreciated by following coal through a power plant and analyzing the effect of coal quality on equipment performance and maintenance. As fuel moisture content decreases, its heating value increases and, assuming constant electric power output of a power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal
