    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 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 centrifugal spreader type feeder that supplies a mixture of particulate limestone and coal to the top of a fluidized bed reactor having a flow of air upward therethrough. Large particles of particulate matter are distributed over the upper surface of the bed to utilize the natural mixing within the bed, while fine particles are adapted to utilize an independent feeder that separates them from the large particles and injects them into the bed.

    摘要: An arrangement that utilizes agglomerating coal as a binder to bond coal fines and recycled char into an agglomerate mass that will have suitable retention time when introduced into a fluidized bed 14 for combustion. The simultaneous use of coal for a primary fuel and as a binder effects significant savings in the elimination of non-essential materials and processing steps.
