| 摘要 |
The invention relates to a combustion device for wood or coal, consisting of a front wall with fuel charging opening, two side walls, a rear wall, a bottom wall, a top wall, a door for the fuel charging opening, a control element for controlling a fresh-air inlet opening, an inner partition which divides the device interior into a precombustion chamber and a postcombustion chamber and has a passage opening between the two chambers, and a grating on the bottom of the precombustion chamber and a smoke gas take-off; in this connection, the partition is arranged horizontally and inserted into its passage opening in a sealed manner is a shaft pipe surrounded by an annular space which is connected to the fresh-air inlet opening; the grating lies on the shaft pipe. For constructionally simple design, and for optimum combustion conditions at the same time, the partition consists essentially of the grating and the latter of a circumferential duct pipe with an inner annular space. To form the grating, tubes can be used, which are connected to the annular space and have slots which are directed laterally, possibly towards the neighbouring pipe. <IMAGE> |
