nov 13, 2016 the initial process in coal based thermal power plant is coal handling.the function of coal handling plant in thermal power plant is to receive process, store, feed the coal bunkers consistently over entire life of the power plant. coal is transported in thermal power station either by railways,roadways or rope ways.
the efficiency of a power plant is affected by the distribution of the pulverized coal within the furnace. the coal, which is pulverized in the mills, is transported and distributed by the primary gas through the mill-ducts to the interior of the furnace. this is done with a double function: dry and enter the coal by different levels for optimizing
function, raw coal introduction. In coal fired power plants, pulverised coal flow from coal mills is to be measured accurately for maximising combustion efficiency and improved dynamic response to load changes. however, realization of this is difficult due to the non-availability of accurate measurement of on-line pulverised coal flow.
