Oct 01, 2014 During this process, the coal particles become smaller due to attrition and collisional forces. Then, the pulverized coal particles move into the classifier volume (4). In the classifier volume, the gas and coal particle mixture exits the pulverizer at a velocity of approximately 30–35 m/s. This high speed forces the coal particles to the ...

Jan 29, 2010 Burning the coal in the combustion process to release the energy in the fuel. Why Pulverizing ? The basic requirement of coal combustion is that all the carbon particles in coal should get sufficient air to burn and release the heat. Coal normally is available to power plants in large lumps ranging from 2 mm to 50 mm size.

Nov 17, 2012 4.4.Classification The circulating air is also used to classify the pulverized coal product prior to carrying it to the burners. The classifier, located on the top of a mill returns the over-size material back to the pulverizer but allows the proper-sized material to pass out of the mill to the burners. classifiers are critical in providing the ...

Oct 25, 2020 Coal classification. There are many compositional differences between the coals mined from the different coal deposits worldwide. The different types of coal are most usually classified by rank which depends upon the degree of transformation from the original source (i.e., decayed plants) and is therefore a measure of a coal's age. As the process of progressive transformation took place, the ...
