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.

Pulverised Coal - an overview ScienceDirect Topics

The heart of a pulverized coal-fired boiler is the pulverizer, also known as the mill. Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speed mills. Pulverized coal burners may be located on the front or opposed walls or in the corners of the furnace. There are two types of fuel-firing systems: bin system and direct-firing system. Coal feeders are either the ...
