Christian, J V

This patent describes a burner for use in burning granulated solid fuel. This burner consists of a head having a lateral inlet opening at one end and an outlet opening at its other end, a combustion chamber communicating the inlet and outlet openings, means defining a passageway communicating with the inlet opening, means for delivering granulated solid fuel to the passageway, means for delivering combustion air to the passageway to mix with the fuel prior to entering the combustion chamber. The combustion chamber includes means defining a cavity surrounding the head and extending along a major portion of the combustion chamber and communicated at one end with the passageway. An air inlet is communicated with the other end of the cavity. In the cavity is formed a spiral duct along substantially the entire length of the cavity and circumscribing the combustion chamber from the air inlet means to the air delivery. There are perforations therein for use in directing combustion air into the container at least a portion of which flows in the direction of movement of the fuel supply into the duct around the head and combustion chamber and to be preheated prior to entry in to the passageway.
