Abstract
A burner assembly according to aspects of the disclosure includes a burner surface carried by a burner, the burner surface extending outward from a front side of the burner, a housing coupled to the burner on a side opposite the front side of the burner, a gasket disposed between the burner and the housing, a thermally anisotropic protective covering located on the front side of the burner and surrounding a perimeter of the burner surface, and an igniter positioned adjacent to the burner surface.
Claims18
A burner assembly comprising:
- a burner plate comprising a burner aperture;
- a burner surface carried by the burner plate and disposed across and extending through the burner aperture and protruding outward from the burner plate;
- a housing coupled to the burner plate;
- a gasket disposed between the burner plate and the housing, wherein a first side of the gasket is directly coupled to the burner plate and a second side of the gasket opposite the first side is coupled to the housing;
- a thermally anisotropic protective covering directly coupled to a front side of the burner plate;
- and
- an igniter positioned adjacent to the burner surface.
A furnace assembly comprising:
- an intake manifold fluidly coupled to a supply line;
- a pre-mix burner assembly fluidly coupled to the intake manifold, the pre-mix burner assembly comprising:
- a burner plate comprising a burner aperture;
- a burner surface carried by the burner plate and disposed across and extending through the burner aperture and protruding outward from the burner plate;
- a housing coupled to the burner plate;
- a gasket disposed between the burner plate and the housing, wherein a first side of the gasket is directly coupled to the burner plate and a second side of the gasket opposite the first side is coupled to the housing;
- an igniter positioned adjacent to the burner surface;
- and
- a thermally anisotropic protective covering directly coupled to a front side of the burner plate.
A furnace assembly comprising:
- an intake manifold fluidly coupled to a supply line;
