  • 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.
  • Types of Boiler Coal Pulverizers Bright Hub Engineering

    Attrition TypeImpact and Attrition TypeImpact Or Hammer TypeCoal feeds onto a steel rotating table. Tapered, cylindrical, or spherical rollers on top of the table, under spring pressure, exert force on the coal particles on the table. When the table rotates, the coal passes between the rollers and the table and gets ground due to attrition. The hot air under pressure carries this ground coal upwards. Larger particles fall back to the grinding table. These coal particles then pass through a classifier where the large particles get separated due to centr

    OverviewHistoryHow it worksCurrent technologiesSteam locomotivesMerchant shipsSee alsoExternal links

    A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnacefor the combustion of solid fuels. Coal is ground to the size of a fine grain into the boiler, mixed wit
