Abstract
1,022,373. Fluidized beds. HEAD, WRIGHTSON & CO. Ltd. Sept. 24, 1964 [Oct. 24, 1963], No. 42077/63. Heading B2H. [Also in Division G1] Apparatus for separating shale from coal comprises two fluidized beds a, b up through which heated or unheated fluidizing gas passes from gas inlets 3, 4 and 6 to a gas outlet 12, through which particles of less than a predetermined size are carried. Magnetite is continuously supplied at 13 to the lower bed b. The magnetite and shale leave through a pipe 9 containing a rotary gas seal 7, the speed of rotation of which is controlled in response to the amount of magnetite detected by a sensing and control device 5 (see Division G1). The coal leaves through a pipe 14 containing a gas-tight valve 15. Magnetite may be separated from the “sinks” and “floats” and recirculated to the lower bed b.
