(57) [Problem] To provide a combustion device for a pellet fuel, the device being able to suppress the accumulation or generation of clinker in a grate part and improve a combustion state of solid fuel having a pellet shape or the like. [Solution] The present invention comprises a fuel transport part 11 that transports a solid fuel, a fuel discharge part 12 that opens vertically upward, and a grate part 13 that combusts the solid fuel. The grate part has a conical fixed grate 13d, a rotating grate 13e that is rotatably disposed on an upper part of the peripheral edge of the fixed grate, and a grate rotary vane 20 that rotates the rotating grate. Clinker is sandwiched and pulverized into small pieces by a rotating grate claw 26 formed on the inside of the rotating grate and a fixed 13c grate claw 27 that protrudes upward from the fixed grate, and the small pieces are removed from the outer peripheral edge of the grate part by a clinker removal device that rotates together with the rotating grate.

PREPOL Step Combustor (SC) – a simple combustion system for solid alternative fuels

Operational experience shows that waste has to be pre-processed in a mechanical plant before its derived fuel can be used in a cement plant with standard equipment. The fuel must be comminuted to 20-50 mm to entrain into the gas stream and totally burnout within the short retention time in the calciner or at the kiln end. Alternatively, solid waste derived fuel ...
