    Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

    Electricity production is the primary use of coal in the United States. Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity.

    thermal power plant is equipped of a large CHP where coal is handled. Such plants consume large quantity of water in order to suppress dust properly which is undesirable. Therefore use of dust collector units at particular places of CHP plant where dust particles are airborne is highly recommended, since it discharges dust in the form of slurry.

    There are total of 28 pulverized coal pipes in the power plant that is chosen as case study. The study is divided into two parts mainly the effect of coal particle size on the wall shear stress and the other is effect of air flow rate on the wall shear stress. In both configurations the wall shear stress is computed as area weighted average.
