• A pulverizer accepts a volume of material to be pulverized which is dependent on the physical dimensions of the mill and the ability of coal to pass through the coal pulverizing system. • The furnace volume and mill capacity in a specific power station may dictate the need to purchase coals which are reactive and easily grind.
BHEL manufactures a complete range of Bowl Mill (Pulveriser) for all supercritical non supercritical thermal power plant applications. Pulverisers are one of the major auxiliaries in a coal fired thermal power station . They are used for grinding the raw coal, so that the pulverised product at desired fineness can fed to and
INTRODUCTION In coal fired power plants, pulverised coal (PF) 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 online pulverised coal flow.
