 — Thermal power plants have pulverized coal-fired boilers. The pulverizer is one of the most important unit of the plant. The coal after being crushed in the pulverizer to a specific mesh size is then taken to the boiler for combustion. The control of pulverized fuel temperature is crucial failing which leads to mill shutdown.

It will not be released until the coal is pulverized and/or exposed to high temperatures in a low humidity environment, which is essentially what is done in a coal pulverizer. The raw coal is ground and exposed to a very low relative humidity. The coal enters the mill at about 80°F and then hot primary air flows over the

 — Most of our pulverized coal plants began life 30 or more years ago, burning eastern bituminous coal. Utility practice at that time was to simply burn the coal particles until the fly ash contains ...

Today's coal-fired utility boiler operation needs pulverizer designs to supply pulverized coal with required throughput and coal fineness, and also perform with lower specific power consumption, especially at reduced mill load.

To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
