firefiting system in coal mill Page 1 of 1
Re: firefiting system in coal mill. If the coal mill temp goes high, it can ignite the coal and result in explosion inside the mill and components. Thats why the CO2 is injected into the mill to create a inert condition, means to reduce the Oxygen content inside the mill to avoid any firing/explosion.
coal mill pulveriser lube oil CJC
coal mill pulveriser lube oil The pulveriser grinds the coal to dust in rotating grinding rollers and sieves, so that it can be used as fuel. The pulveriser lube oil is subjected to extreme levels of very fine particles, and many power plants believe the plant should be shut down periodically to change the oil.

Modeling and control of ball mill system considering coal ...
The established coal mill model is based on the following assumptions: (1) the process of coal grinding is simplified by disregarding the separation of coal particles; (2) the grinding and delivery of pulverized coal are divided into two stages in the mill; and (3) pulverized coal sizes at the outlet is neglected in the model, and only raw coal and pulverized coal exist in the mill.
Why Pulverized Coal is Used in a Power Plant
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. A 2000 MW power station could be handling coal in the range of 1600 tons/hr or around 12 million tons of coal annually.
