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. Coal is commercially available in different sizes known as “Run of Mine," “stoker,".

How much is pulverized coal particle size important in power .It is certainly important, as the extent to which the coal is pulverized will factor into complete combustion. Too big and the fuel will not burn entirely, leading to a lot of wasted fuel. Coal pulverizers have classifiers that restrict the size o.The Problem of Fine Particles - POWER MagazineSep 30, 2008 . No matter what its size, fine particulate matter is a serious matter for coal-burning power plants. A process that charges those particles shows promise for mitigating the problem.

Preliminary investigation on the effects of primary airflow to coal .

This paper presents an investigation on the effects of primary airflow to coal fineness in coal-fired boilers. In coal fired power plant, coal is pulverized in a pulverizer, and it is then transferred to boiler for combustion. Coal need to be ground to its desired size to obtain maximum combustion efficiency. Coarse coal particle size.
