• Why Pulverized Coal is Used in a Power Plant Bright Hub

    Coal For Power PlantsWhy Pulverizing GrindabilityThe basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat.Coal normally is availe to power plants in large lumps ranging from 2 mm to 50 mm size. Coal is commercially availe in different sizes known as “Run of Mine,\" “stoker,\" “slack,\" etc. depending on their size.In the olden days, coal burning was done on grates without any change in size or pulverizing. Because of the large size of coal, some of the carbon

    Prior to the developments leading to the use of pulverized coal most boilers utilized grate firing where the fuel was mechanically distributed onto a moving grate at the bottom of the firebox in a partially crushed gravel like form. Air for combustion was blown upward through the grate carrying the lighter ash and smaller particles of unburned coal up with it, some of which would adhere to the sides of the firebox. In 1918 The Milwaukee Electric Railway and Light Company, later Wisconsin Electric, conducted tests in t
