  • coal drying improves performance and reduces

    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 handling system. crushed coal
