Abstract
The invention relates to a furnace with a body (1) of a furnace, at the lower end of which a discharge device (2) for the ashes produced in the combustion chamber is provided. A continuous conveyor device in the form of a vibrating conveyor (3) is mounted below the discharge device (2). The vibrating chute of said vibrating conveyor reliably and effectively removes the dry ashes which are at the same time cooled with air.
Claims10
A furnace comprising:
- a firebox;
- at least one discharge device disposed at a lower end of said firebox for dry ash from a combustion chamber of said firebox;
- a continuous-flow conveyor, in the form of a vibrating conveyor, disposed below said discharge device for receiving and removing discharged ash in a dry state, wherein said conveyor is provided with a vibrating trough that is open toward said at least one discharge device, and wherein said vibrating trough forms an upper wall of an air receiver that adjoins said firebox;
- means for cooling said ash with air, wherein cooling air is utilized as preheated combustion air for said firebox, and wherein a base of said vibrating trough is provided with nozzle openings for the passage of cooling air;
- and
- a blower, wherein said air receiver is connected to said blower.
