The main Function of the Pulveriser in thermal power plant is to crush/grinding the raw coal coming from coal handling system through coal feeder into a predetermined size in order to increase the surface area of the coal. If the coal is not pulverised, the coal might not burn completely, thus resulting in wastage of fuel.
CONVEYOR SYSTEMS Hot inclusions on coal or coke conveyors can go undetected before causing substantial damage. Traditional methods such as visual inspections or singlepoint pyrometers often have dificulty detecting these hot spots on a moving conveyor.

This study shows the performance of a currently running vertical roller coal mill (VRM) in an existing coalfired power plant. In a power plant, the coal mill is the critical equipment, whose ...
The coal mill is an important part of the coalfired power plant because it is used to crush and grind the coal into a fine powder, which increases the efficiency of the coalburning process.
A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.
Introduction Despite the recent surge in renewable energy, fossil fuels including coal are expected to provide nearly 22% of the global power and account for majority of CO 2 emissions by 2040 (IEA, 2021). Therefore, identifying ways to optimize operation of existing and upcoming coal fired power plants is essential.
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
After hand picking foreign material, coal is transported to the Crush house by conveyor belts where it is crushed to small pieces of about 20 mm diameter. The crushed coal is then transported to the store yard. Coal is transported to bowl mills by coal feeders. 3. Bowl Mill. The coal is pulverized in the bowl mill, where it is grounded to a ...
