More than 50% of its weight is made up by carbon. Therefore it is classified as highrank coal. Other fossil fuels like subbituminous coals with high moisture contents as well as brown coal and lignite are lower ranked. Lignite, which is the lowest ranking fossil fuel, is defined between peat and hard coal. Petcoke is not a natural product.

In coalfired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to coal crusher: Used for larger coal size.

As petcoke has a higher energy content, petcoke emits between 30 and 80 percent more CO2 than coal per unit of weight. The difference between coal and coke in CO2 production per unit energy produced depends upon the moisture in the coal (increases the CO2 per unit energy — heat of combustion) and volatile hydrocarbon in coal and coke ...
