  • Why Pulverized Coal is Used in a Power Plant Bright Hub
    Coal For Power PlantsWhy Pulverizing ?GrindabilityThe coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process.Before going into the details, let us look at the quantity of coal processed in a power plant. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually. A single 500 MW unit consumes in the range of 400 tons/hr of coal.
