Abstract: 1495490 Controlling combustion in fluidized beds ROLLS-ROYCE Ltd 13 Oct 1975 [17 Oct 1974] 44947/74 Heading F4B [Also in Division F1] The coal supply to a fluidized bed is controlled in accordance to the bed temperature. A coal burning fluidized bed 12, Fig. 1, has an air heating element 14 immersed in the bed and a metal encased quartz rod 30 operating a shutter 26 which diverts coal delivered pneumatically along line 22 to a line 24 feeding the coal bed, when the bed temperature drops. The shutter 26 is operated mechanically or by any suitable form of position transfer mechanism. When the bed temperature rises the coal is returned to store by a line 28. The air and cleaned bed exhaust are used to drive a turbine 15b which drives a compressor 15a supplying the bed. In a modification, Fig. 2, the coal supply to a fluidized bed 12 through which the whole of the gas driving a turbine 15 passes, is controlled in accordance with the signal from a thermocouple 42 which operates a shutter 50 controlling the discharge from a hopper 52 feeding fuel to a pneumatic supply line 28. The discharge from the hopper may be controlled by a rotary pocketed valve, driven at a rate dependent on the sensed temperature of the bed. The carrier air may be pulsed and duets feeding different parts of the bed may be blown in turn, so that the supply to a region of the bed may be varied in accordance with local temperature variations.

A curved cutting edge 782 of the blade first cuts the material edge and then the blade is rotated until a blunted tearing edge enters the cut and the cutter is moved across the material so that it is torn between two adjacent cords. As it is torn the ply material is lifted along the pathway the blade will follow and the blade is heated to cause the ply material to flow and seal the cut and torn edges. Air blown through jets lifts the material during tearing.
