The powdered coal from the coal mills is carried to the boiler in coal pipes by high pressure hot air.The pulverized coal air mixture is burnt in the boiler in the combustion zone. Generally in modern boilers tangential firing system is used i.e. the coal nozzles/ guns form tangent to a circle. The temperature in fire ball is of the order of 1300 deg.C.
Producing electricity in coal power plants can take place in a number of ways with varying degrees of efficiency. In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a …

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...

used to control the steam temperature inside the boilers. Optimizing this burner tilt angle can have an appreciable effect in controlling NO x emissions.7 Thus, by controlling the existing boiler operating parameters (like burner tilt, excess air, coal mill operations etc.) plants can have a measurable impact on NO x emissions.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.

The mills can be used either for dry or wet, rod or ball grinding. By using a separate attachment the discharge end can be changed so that the mills can be used for peripheral instead of overflow discharge. The lining is generally made as a plate of wear resistant steel with welded on lifters. The heads are bolted onto the shell which ...
The coal contains approximately 40 percent moisture and 12 percent ash. At full load, each unit fires approximately 900,000 lb/h of coal. The boilers are controlled circulation, radiant, single reheat, tangentially fired, balanced draft with divided furnace. Each boiler is equipped with eight mills feeding eight elevations of tilting fuel nozzles,
2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill.

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.
