Abstract
Embodiments of a fire pit insert include a mixing tube with a fuel outlet end, a soundwave input end located below and horizontally offset from the fuel outlet end, and a fuel inlet located between the fuel outlet end and the soundwave input end. A fuel distribution chamber connected to the fuel outlet end has a top plate with orifices, a bottom plate spaced apart from the top plate, and a baffle located between the top and bottom plates. The baffle is arranged coaxial to the fuel outlet end.

A fire pit insert comprising:
- a mixing tube including
- a fuel outlet end at one end of the mixing tube,
- a soundwave inlet end located at another end of the mixing tube below and horizontally offset from the fuel outlet end, and
- a fuel inlet located between the fuel outlet end and the soundwave inlet end, the soundwave inlet being upstream of the fuel inlet;
- and
- a fuel distribution chamber connected to the fuel outlet end of the mixing tube, the fuel distribution chamber including
- a bottom plate,
- a top plate with a plurality of orifices and sloping sidewalls extending in a downwardly outward direction toward the bottom plate,
- the bottom plate spaced apart from the top plate by the sloping sidewalls,
- a gasket located between the top and bottom plates and providing a gas tight seal between the top and bottom plates, and
- a baffle arranged coaxial to the fuel outlet end.
A fire pit insert comprising:
- a mixing tube including
- a fuel outlet end,
- a soundwave inlet end located below and horizontally offset from the fuel outlet end, and
- a fuel inlet located between the fuel outlet end and the soundwave inlet end, the soundwave inlet end being located upstream of the fuel inlet;
- and
- a fuel distribution chamber including
- a bottom plate;
- a top plate with a plurality of orifices and sloping sidewalls extending in a downwardly outward direction toward the bottom plate,
- the bottom plate spaced apart from the top plate by the sloping sidewalls and connected to the fuel outlet end of the mixing tube, the bottom plate including a concave-shaped central opening coaxial to the fuel outlet end of the mixing tube, and
- a gasket located between the top and bottom plates and providing a gas tight seal between the top and bottom plates.
A mixing tube for a fire pit insert comprising:
- a mixing tube including
- a fuel outlet end located at an uppermost end of the mixing tube;
- a soundwave inlet end located at another end of the mixing tube;
- a fuel inlet located between the fuel outlet end and the soundwave inlet end and toward the soundwave inlet end, the soundwave inlet end being located upstream of the fuel inlet and the fuel outlet end being located downstream of the fuel inlet;
- at least one bend located between the fuel outlet end and the soundwave inlet end, the bend including a lowermost end of the mixing tube;
- a fuel distribution chamber including:
- a bottom plate;
- a top plate with a plurality of orifices and sloping sidewalls extending downwardly outward toward the bottom plate;
- the bottom plate spaced apart from the top plate by the sloping sidewalls and connected to the fuel outlet end of the mixing tube, the bottom plate including a central opening located coaxial to the fuel outlet end of the mixing tube;
- and
- a gasket located between the top and bottom plates and providing a gas tight seal between the top and bottom plates.
