摘要： A bowl mill for pulverizing coal, wherein two bowl surfaces are rotated on the same shaft. The raw crushed coal is pulverized in one of the bowls, and the pulverized coal therefrom is then transported in an air stream to a classifier from where the fines are carried on to the ultimate point of use, and the more coarse particles are discharged into the second bowl for further grinding.

摘要： A method of operating a pulverized coal furnace wherein the coal is introduced with minimal oxygen through an intermediate zone of the furnace which also has a relatively low oxygen content. The carbon particles are projected into an upstream portion of the furnace where secondary air is introduced to burn the carbon particles. The combustion products pass upwardly through the intermediate zone to a downstream zone where tertiary air is added to complete combustion.

摘要： An integrated method of removing alkali metal compounds from sulfur-bearing coal is disclosed. The coal is comminuted (4) and mixed (10) with water (8) to form a slurry (12). In the preferred embodiment, the slurry (12) is comingled with an SO.sub.2 -bearing gas (16) in a transport pipeline (52) to form an acidic slurry which dissolves the alkali compounds out of the coal. The slurry is then separated (22) into a solid portion (24) and a liquid portion (26), the solid portion (24) being combusted (34) to form the SO.sub.2 -bearing gas (16).

摘要： A furnace in which fuel, such as pulverized coal, is burned, with the fuel and air being introduced into the furnace through tangential burners located in each of the four corners thereof and being directed tangentially to an imaginary circle in the center of the furnace. The invention will be described with pulverized coal, but is not limited to coal. Combustion gases from downstream of the furnace are recirculated back to the furnace, and are also introduced into the furnace from the four corners, in a tangential manner. The coal is introduced along with primary air to be directed at the smallest of a series of concentric imaginary circles; the recirculated gases are directed tangentially at a somewhat larger imaginary circle; and the secondary air is directed tangentially at a still larger imaginary circle.

摘要： An entrained flow coal gasifier wherein a high temperature product gas stream is essentially formed by burning char with air. Additional char, formed by partial gasification of coal, is added immediately thereafter to obtain the gasification reaction. Fresh coal is thereafter supplied in a lower temperature region thereby obtaining the volatile components driven off at a relatively low temperature.

摘要： A conventional pulverized coal-fired furnace is supplied fuel at two different levels. The raw coal is classified into a stream of relatively pure coal ground to conventional fineness for burners at the lower level, and a stream of very finely divided coal with a large, heavy mineral content for burners at the higher level.
