While grinding the coal, the pulverized coal is taken out of the coal mill from the discharge device by a special induced draft fan. The coarser coal granules will return to the grinding chamber through the return screw of the discharge device for regrinding.

The pulverized material is carried out of the mill by the flow of air moving through it. The size of the pulverized particles released from the grinding section of the mill is determined by a classifier separator. If the coal is fine enough to be picked up by the air, it is carried through the classifier.

Definition of pulverization. "Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains ...

A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer puritch is used to pulverize coal for combustion in the steam-generating furnaces of coal power plants.

Raw coal enters through the center of the mill and is deposited on the grinding table. Centrifugal force feeds the coal radially outward where it is ground between the roller tyres and grinding track. Sectional View of the mill Siddhartha Sankar Bharali M6B194 5 The pulverized coal is flowed by

Pulverized coal firing ensures complete combustion of coal, thus ensuring higher efficiency of steam generators. It is predominantly adopted in large coal-fired utility boilers. The finer the grinding of coal, the more efficient its combustion.

Integral fan purges the pulverizer of coal dust after the coal feed is stopped As raw coal and primary air enter the crusher section during start-up, air temperature is lowered as coal moisture is evaporated and only relatively cool air comes in contact with the pulverized coal Easy Access for Maintenance

Ans- The coal power plant uses Pulverized coal firing to ensures complete combustion of coal which helps in achieving higher efficiency of steam generators. The finer the grinding of coal, the more efficient its combustion working of coal power plant… View the full answer

Pulverized Coal Injection (PCI) is a process that involves blowing large volumes of fine coal granules into the BF. This provides a supplemental carbon source to speed up the production of metallic iron, reducing the need for coke production. As a result energy use and emissions can be reduced. However, as coke provides physical support and gas permeability in the BF, its complete ...
