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
2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the …
Pulberising Coal Mill With Classifiers In Power Plant . The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force 510 the modern coal mill classifier however often has an impeller mounted close to the exit of the mill chamber the impeller is a .
There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen's Ratcliffe-on-Soar power station has demonstrated significant fineness gain, especially at the coarse end of the particle size distribution curve, and minimal effect on mill coal throughput and operability, with greatly reduced in vibration levels.

produced by the thermal power plants Coal classification is the final stage[1]. of processing before the combustion of the pulverized ground coal. The ground coal has a wide range of particle sizes ranging from about 7590 µm according to the - mill types. The classifier designed to maintain a limited class of particle sizes and
In pulverized coal-fired (PCF) power plants (PPs), coal is pulverized in a mill, and it is then transferred to the burners and furnace volume for combustion. Depending on the physical and chemical properties of the coal, different types of pulverizing systems (e.g., vertical and horizontal air-swept ( Fig. 1 a and b )) can be used.

The lower limit of the furnace volume is dominated by the space required for burning the fuel completely, or to an extent less than the allowable unburned fuel loss. To complete the fuel combustion within the furnace space, the fuel injected into the furnace has to reside there for a longer than critical time t r. The residence time of the combustion gas produced in the furnace can also be ...
