Abstract
A fuel management system for a biomass furnace features a common drive motor operatively coupled to both a fuel delivery conveyor, which is arranged to support and displace fuel during combustion in a combustion chamber of the furnace, and an ash removal conveyor which is arranged to transfer ash generated by the combustion out of the combustion chamber. The system also features ducting which extends around the fuel delivery conveyor to convey airflow generated by a blower for subsequent discharge both below and above the fuel during combustion. Furthermore, the system features a housing which operably supports at least the fuel delivery conveyor and which is arranged to be removably insertible into the combustion chamber of the furnace.
Claims18
A fuel management system for a biomass furnace having a combustion chamber, comprising:
- a fuel delivery conveyor arranged to be located in the combustion chamber for receiving biomass fuel to be combusted therein, the fuel delivery conveyor defining a support surface for supporting the fuel during combustion and being operable to displace the fuel as the fuel is being combusted in the combustion chamber;
- an ash removal conveyor operatively communicated with the fuel delivery conveyor to receive therefrom ash generated by the combustion of the fuel, the ash removal conveyor being arranged to transfer the ash to a location external of the combustion chamber;
- an ash transfer conveyor arranged externally of the combustion chamber and operatively communicated with the ash removal conveyor to receive the ash therefrom, the ash transfer conveyor being transversely oriented to the ash removal conveyor and being operable to displace the ash in a transverse direction to the discharge direction;
- a common drive motor operatively coupled to both the fuel delivery conveyor and the ash removal conveyor to actuate the fuel delivery conveyor to displace the fuel and the ash removal conveyor to displace the ash, wherein the ash transfer conveyor is also operatively coupled to the common drive motor so as to be actuated thereby to displace the ash in the transverse direction;
- wherein the fuel delivery conveyor is operable to displace the fuel in a conveyance direction of the fuel delivery conveyor and the ash removal conveyor is operable to displace the ash in a discharge direction which is substantially parallel to the conveyance direction of the fuel delivery conveyor;
- wherein drive shafts of the fuel delivery conveyor and the ash transfer conveyor are substantially parallel and a drive shaft of the ash removal conveyor is transversely oriented to the drive shaft of the fuel delivery conveyor;
- a first transmission operatively interconnecting the common drive motor and the drive shaft of the ash removal conveyor;
- and
- a second transmission operatively interconnecting the common drive motor and the drive shaft of each of the fuel delivery conveyor and the ash transfer conveyor.
