    Coal Drying Improves Performance and Reduces

    since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders. Dryer coal flows more readily and causes less feeder hopper bridging and plugging problems. Coal feeders provide coal to the coal pulverizers (mills) where the coal is

    Jan 21, 2022 Dry cooling systems have relatively high capital costs and require more energy to operate. These factors result in lower overall power plant efficiency, but dry cooling systems use about 95% less water than wet systems. Many types of power plants generate electricity by boiling water to produce steam, which is then passed through a turbine. Plants that burn coal

Ideally, there is 30-35% reduction of moisture from wet coal, -18% of moisture. But In actual condition in the power plant, it may reduce to about 6-7%
