Mitsubishi Power | Pulverizers
Boilers. 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.

There are many types of mills available, but proper selection will enhance the reliability in achieving a consistent boiler and cycle efficiency.
Coal Mill - an overview | ScienceDirect Topics
To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.
Large-scale biomass combustion plants: an overview ...
Biomass boiler dusts tend to stick to the heat transfer surfaces and form hard deposits when they are between T15 and T70. An example showing the effect of water content on material behaviour is plaster. If it is dry, it will fall off the wall. If there is too much water the plaster will again fall off the wall.
