By Noah Beecher Kelk Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of nearpure carbon ...

26/08/2009 · Is There Some Light at the End of Coal's Long, Dark Tunnel? Some think that the only way to clean up coal is to stop burning it altogether. Now a handful of researchers and companies are pursuing a technology to do just that, but one that has the potential of keeping part of the nation's economy coalfired. They are skipping the burning step.
The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of coal according to the boiler demand and the amount of air available for drying and transporting the pulverized coal fuel is controlled by ...
The country depends on coal for about 80% of Its energy needs, more than any other modern Industrial nation. The possibility of producing hydrocarbons from coal has always attracted the attention of Its scientists.
