If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.

Thermal Power Plant : Principle, Parts, Working

Sep 17, 2017 A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy of fluid into mechanical energy) and

For best results, mills should be tested and maintenance driven by the test data collected, not by hours of operation or tons of throughput. We call this, “Performance Driven Maintenance”. It is surprising to us that many plants do not perform mill maintenance and overhauls based on accurate coal fineness and distribution test data.
