Combustion device for solid fuel

摘要

Combustion device for solid fuel in particular granular material. The device comprises a fuel dosing device (12) with one in a cylinder formed house (19) rotatable dosing chamber (18). The dosing chamber is so formed that during rotation it successively supplies fuel through the dosing device (12) in such a way that its intake port (10) and the outlet port (17) of the dosing means cannot at any occasion communicate. The dosing device (12) is axially connected to a fuel conveyor (14), which supplies fuel to a combustion chamber (15). The dosing chamber (18) and the fuel conveyor (14) have a power transmission connection and are arranged to be run by a common driving device (27). The invention also concerns the combustion chamber of the combustion device. The fuel conveyor is arranged essentially axially in relation to the longitudinal direction of the combustion chamber. On the inner wall (43b) of the combustion chamber is arranged in level with and in the extension of the centre axis (42) of the fuel conveyor at least one guide rail (43) which directs an air stream diagonally against the opposite inner wall of the combustion chamber. The invention also concerns a method for combustion of solid fuel.
