Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

Abstract. The main task of this design is to process coal from coal source into pulverized coal and supply it to the original coal bunker for combustion and power generation. In the design, Siemens CPU3152DP is used as the main control unit to control all the components of the coal transportation system of the power plant.

transportation fuel. There are two commercially demonstrated routes for converting coal to transportation fuels through gasification (Figure 1). The widely known FischerTropsch process was first discovered in the 1920s. It has been commercially practiced by in several different forms to produce fuels from either coal or natural gas.
