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.

The pulverized coal processed by the CLIRIK coal mill is fully burned and has a high utilization rate. It has provided technical support for dozens of power plants. When the humidity of the raw coal is below 15%, the CLIRIK coal pulverizer is used to grind the raw coal into 200 meshes.

The bowl mills are further divided into deep bowl or shallow bowl mills. • Impact mill: These are high-speed impact machines that use beater wheels to crush the coal. 12. Ball & Tube Mills Tube mills: The tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder.

This machine is driven by the 22 kW asynchronous motor by means of the reduction planetary gear of the resultant ratio 1:5.33.The static characteristic of this motor as well as the drive system first torsional eigenform of frequency 4.2 Hz are shown in Figs. 2a and 2b, respectively.

Pulverizer housing or burner lines are glowing red. Mill fires require immediate attention to prevent damage to the pulverizer and more damaging mill "puffs". Explosions in a pulverized coal system are normally called "puffs.". A mill puff is an explosion in the mill system caused by an explosive combination of coal, air and temperature.

Coal for Power Plants. The coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant.
