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.

Much of the improvement can be traced to the need to achieve higher fineness levels. As we have mentioned before, our goal for optimum combustion is to attain a minimum of >75% passing 200 Mesh with <0.5% remaining on the 50 Mesh at pulverizer full load. Higher fineness at full load can cause extremely high fineness at lower coal flows.

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.
