  • Kids Korner Processing Coal Apogee Interactive

    Processing Coal. Once the coal has been mined it needs to be processed. The coal first goes to a preparation plant where it is washed or cleaned to remove contaminants. The cleaning removes impurities like rocks, ash, sulfur and other substances. Coal that is going to be burned in solid form may go through a variety of preparation processes 1.2 Anthracite Coal Combustion US EPA,1.2 Anthracite Coal Combustion 1.2.1 General1-5 (which tends to react with and bind coal sulfur in the bottom ash as sodium sulfite or sodium sulfate). For FBC boilers, SOx emissions are inversely proportional, in general, to the molar ratio of calcium (in the limestone) to sulfur (in the fuel) added to

    underground coal mine. Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. TRANSPORTING COALBackground Information-- How does burning coal affect ,Background Information-- How does burning coal affect the environment? ash, called "fly ash," are released. The sulfur in coal combines with oxygen to form sulfur dioxide, which can be a major source of air pollution if emitted in large enough quantities. Further processing utilizes the different gravities of coal and impurities to
