Abstract

1475991 Fluidized fed combustion apparatus FLUIDFIRE DEVELOPMENT Ltd 11 April 1974 [18 Jan 1973] 2657/73 Heading F4B In a fluidized combustion apparatus having a bed support arranged so that in use the bed has a deeper part and a shallower, combustible material is fed to the deeper part of the bed through a shoot 28 without depositing material in the surface of the shallower part of the bed, and the material within the bed circulates as shown by the arms 50, 51. A gas/air mixture is fed through shallow cooled ducts 19 to tiles 14 arranged to form a trough. A central opening 15 has an inclined floor leading to a valved outlet for oversized residues (Fig. 3). The fuel gas supply to the tiles 14 may be turned off when a suitable temperature has been reached, and operation continued with solid fuel or garbage supplied through shoot 28. Side beds on supports 13 are fluidized only when a suitable temperature has been reached, and contain bent transfer tubes as described and claimed in Specification 1,475,992.
