Abstract
Combustion appliances for providing heat for cooking meats and other foods are provided. The appliances are self-stoking, in that they do not need to be repeatedly re-filled with more fuel periodically, such as during an 18-hour slow cook procedure. A venturi assembly is provided which consists of a venturi duct and baffle, which creates a higher flow, lower pressure region within the venturi assembly, which gases mix with spent combustion gases to provide a more uniform temperature output.
Claims17
A combustion appliance useful as a heat source for cooking foods, comprising:
- a) a lower chamber having an interior volume and comprising:
- i) a bottom portion;
- ii) a wall portion having a door hingedly-attached thereto;
- iii) an upper portion;
- and
- iv) a hole disposed through said wall portion;
- b) a hollow body having an interior volume, a lower end, and an upper end, said lower end being attached to said upper portion of said lower chamber;
- c) a lid removably affixed to said upper end of said hollow body;
- d) an aperture disposed through a wall of said hollow body;
- e) a venturi duct comprising an upper opening and a lower opening positioned on an outer surface of said hollow body, said venturi duct being configured and disposed such that said aperture resides within said venturi duct;
- f) a baffle present within said venturi duct, configured and disposed to provide a partial-restriction of air flow within said venturi duct upwards from said lower opening of said venturi duct to said upper opening of said venturi duct;
- and
- g) a grate disposed between said inner volume of said lower chamber and said lower end of said hollow body.
