Abstract
A fire pit includes an engine having at least one wall defining an inner chamber. At least one primary air aperture is defined through the inner chamber wall at a first, lower level, and at least one secondary air aperture is defined through the inner chamber wall at a second, upper level. A fuel grate is supported within the inner chamber at a level between the lower level and the upper level.
Claims20
A fire pit comprising:
- an engine having at least one wall defining an inner chamber;
- at least one primary air aperture defined through the inner chamber wall at a first, lower level;
- at least one secondary air aperture defined through the inner chamber wall at a second, upper level;
- and
- a fuel grate supported within the inner chamber at a level between the lower level and the upper level;
- wherein solid fuel supported by the fuel grate, when combusted, is provided primary combustion air from below the fuel grate by the primary air apertures and provided secondary combustion air from above the solid fuel by the secondary air apertures, the secondary combustion air promoting combustion of unburned gasified combustibles rising within the inner chamber.
3 more elements
A fire pit comprising:
- a shroud having a first air flow region admitting air from outside the shroud to inside the shroud;
- an engine at least partially contained within the shroud, an intake chamber being defined between the engine and the shroud, and an inner chamber being defined by at least one engine wall;
- wherein the engine has at second air flow region admitting combustion air from the intake chamber to the inner chamber;
- and
- wherein the inner chamber has a tapered configuration having a smaller horizontal cross-sectional area toward a top thereof than a bottom thereof.
2 more elements
A fire pit comprising:
- an engine formed from four inwardly walls such that an interior combustion chamber is defined by the sidewalls to have a larger bottom cross-sectional area and a smaller top cross-sectional area;
- and
- a shroud surrounding the engine and spaced apart therefrom to define an air intake region therebetween;
- wherein the engine provides a plurality of primary air apertures along a bottom of at least one of the four inwardly angled walls admitting primary combustion air from the intake region into the combustion chamber;
- and
- wherein the engine provides a plurality of secondary air apertures along a top of at least one of the four inwardly angled walls admitting secondary combustion air from the intake region into the combustion chamber.
