However, once we burn a lump of coal, that coal is gone – we cannot reuse it. When we mine a coal mine to extract the coal from it, we reduce the overall amount of coal that exists in that mine. There have been long running debates about the advantages and disadvantages of nonrenewable energy sources.

coal in the Powder River basin and the very large, inexpensively minable surface deposits in the basin are economic barriers to underground mining in this region at least throughout this decade. A potential method for recovering energy from coal is through in situ gasification of deep coal seams that cannot be mined by surface mining methods.

Coal quality is therefore determined by the type of vegetation that formed it, how deep it is buried, and what pressure and temperature is present at the site of the deposit. Coal can be an amazing energy resource. It could also lead to the eventual destruction of humanity. Here are the major advantages and disadvantages of coal to consider.

The classification of coal will depend on heat generation, carbon content, and ash content. Each type of coal will have its own advantages and disadvantages, as follows: Coal: is black or brownblack coal. Coal is usually rarer than brown coal and has faint light. Coal is very brittle and when heated, it will have a temperature of 900 1100oC.

The pulverized coal furnace attempts to burn finely powdered coal and air in a gaseous torch. This is accomplished through pulverizing the coal by crushing, impact and attrition (rubbing) of the coal to a size finer than face powder (diameter < mm). The primary air dries and transports the coal.
