Through this process, CO 2 is reduced by carbon to produce two CO molecules, and H 2 O is reduced by carbon to produce H 2 and CO. Both H 2 and CO are combustable fuel gases, and those fuel gasses can then be piped off to do desired work elsewhere. Combustion and Drying: These are the most easily understood of the Five Processes of Gasification.

An alternative, more complex but more accurate method for the estimation of drying performance is the technique based on dimensionless drying curves as initially developed by Hukill (1947). The methodology permits the estimation of the moisture content of grain at any level within the bed at any time after initiation of drying.

Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants.A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the media).

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.

the drying air. This, in turn, is necessary for even heating and drying of the sewage sludge. The layer of material on the belt forms a filter medium for the air flowing onto the granulate layer from above and thus pre-vents entrainment of dust. The low tem-perature of the drying gases (< 150°C) and the low dust content in the system facilitate
