| 摘要 |
The present invention is directed to a by-product fuel delivery assembly (5) for delivering by-product fuel to a fluidised bed unit (3), the by-product fuel delivery assembly comprising a fuel hopper (25), a fuel conveyer (29) and a fuel metering device (27). The fuel hopper comprises a fuel feed mechanism (71) that comprises a plurality of laterally arranged push bars (55) and a plurality of laterally arranged stop bars (57). The push bars and stop bars co-operate to feed by-product fuel sifting on the base of the fuel hopper along the base of the fuel hopper towards the discharge slot (59) of the fuel hopper and provides a simple, effective, low-cost and low maintenance solution to the problem of feeding by-product fuel from the fuel hopper. The invention is also directed to embodiments of the fuel conveyer using a link chain (95) and a fuel metering unit using a pair of contra rotating fuel feed augers (75,77). <Figure 1> |
