coals because it reduces the heating value (water does not burn!) and its weight adds to the transportation costs of coal. This is a problem for the lowsulfur subbituminous coals from Wyoming, which are currently very popular with electric power plants (see Investigations 72 and 73). When a coal sample that has been dried to remove its moisture is heated in the absence. environmental pollut

design calculations to determine the required thickener area, the most important design parameter, and ultimately the maximum steady state underflow concentration that is possible for a given solids throughput. In addition, the capital cost ofa thickener will be dependent on the calculated required settling area. Therefore, it is important to provide adequate area but avoid .

· Coal mill dust collectors have a substantial effect on productivity, yet have received relatively little attention as companies implement costsaving programs, like the use of petcoke as a fuel reduction measure. Petcoke is typically ground finer than coal, and it has a particularly sticky nature that makes it more difficult to clean from filter bags. Its high sulfur content increases the ...

· The seeds have to be added to a saturated if not supersaturated solution. The saturation temperature corresponding to a feed concentration of Kg/Kg can be calculated to be 48 O C from the solubility relationship. It is therefore necessary to cool the feed from 50 O C to 48 O C, seed the crystallizer with grams of 100 µ m seeds, and follow the temperature profile as determines below.
