Smoke generating apparatus
First Claim
1. In a smoke generating apparatus, including a housing having an outlet opening formed therein, and a combustion chamber therebelow, infeed means for gravitationally conducting combustible material into the combustion chamber and a rotatable burner assembly, comprising a supporting wall spaced below the infeed means, an annular wall projecting upwardly from the supporting wall in enclosing relation to the combustion chamber, heat emitting means mounted on the annular wall internally of the combustion chamber for combustion of the material accumulated thereon and means responsive to rotation of the burner assembly for radially impelling the material fed into the combustion chamber toward the annular wall to accumulate the material on said heat emitting means.

Abstract
An annular wall extending from a bottom wall foundation of a rotating burner assembly encloses a combustion zone into which combustible material is fed. An energized heating element mounted on an internally concave, heat insulating surface of the annular wall has the combustible material accumulated thereon during rotation to generate smoke upwardly withdrawn from the combustion zone.

- 1. In a smoke generating apparatus, including a housing having an outlet opening formed therein, and a combustion chamber therebelow, infeed means for gravitationally conducting combustible material into the combustion chamber and a rotatable burner assembly, comprising a supporting wall spaced below the infeed means, an annular wall projecting upwardly from the supporting wall in enclosing relation to the combustion chamber, heat emitting means mounted on the annular wall internally of the combustion chamber for combustion of the material accumulated thereon and means responsive to rotation of the burner assembly for radially impelling the material fed into the combustion chamber toward the annular wall to accumulate the material on said heat emitting means.
- 13. In a combustion apparatus, a rotor assembly comprising an annular heat reflective wall enclosing a combustion zone between opposite axial ends thereof, a supporting wall fixed to the annular wall at one of said axial end, a drive shaft connected to the supporting wall through which rotation is imparted to the annular wall, passage means extending into the combustion zone at the other of said ends of the annular wall for conducting an infeed of the combustible material and exhaust of combustion products in counter-current relation to each other, and heat generating means mounted internally on the annular wall for combustion of the material accumulating thereon.
- 19. In a smoke generating apparatus including a housing having a combustion chamber therein, infeed passage means for conducting combustible material into the combustion chamber and heat generating means for combustion of the material within the combustion chamber, the improvement residing in a burner assembly comprising annular wall means on which the heat generating means is mounted for focusing heat emitted therefrom internally within the combustion chamber, a bed support connected to the annular wall means and rotatable therewith in spaced relation to the infeed passage means and impeller means mounted on the bed support for impelling the combustible material onto the heat generating means.
- 27. In a smoke generating apparatus including a housing having a combustion chamber therein, infeed passage means for conducting combustible material into the combustion chamber and heat generating means for combustion of the material within the combustion chamber, the improvement residing in a burner assembly comprising a rotatable rotor enclosing the combustion chamber into which the material is deposited by the infeed passage means, blower means connected to the rotor for inducing exhaust flow therefrom in response to rotation of the rotor, means for axially displacing the infeed passage means between loading and smoke generating positions, sealing means mounted on the infeed passage means for preventing infeed of the material into the combustion chamber in the smoke generating position of the infeed passage means and means responsive to said displacement of the infeed passage means to the loading position for blocking said exhaust from the combustion chamber induced by the blower means during rotation of the rotor.
- 31. In a combustion apparatus, a rotor enclosing a combustion zone, heating means mounted in operative relation to the combustion zone for combustion of material therein and drive means for imparting rotation to the rotor and the heating means during combustion of the material within the combustion zone.
