Abstract
A burner assembly for providing a flame and combustion gas to a plurality of inlets includes a burner frame having a channel formed therein. The channel extends parallel to a longitudinal plane defined by the plurality of inlets. A burner is mounted within the channel of the burner frame. The burner is arranged in fluid communication with the plurality of inlets. A burner bracket is used to mount the burner assembly within a burner box. The burner bracket defines a cavity within which the channel of the burner frame and the burner are positionable.
Claims20
A burner assembly for providing a flame and combustion gas to a plurality of inlets, comprising:
- a burner frame having a first member and a second member, the first member having an opening formed therein and the second member protruding from a downstream surface of the first member, the first member extending about a periphery of the opening to form a channel, the channel extending parallel to a longitudinal plane defined by the plurality of inlets;
- a burner connected to the second member and arranged within an interior of the channel formed by the second member of the burner frame, the burner being arranged in fluid communication with the plurality of inlets;
- and
- a burner bracket for mounting the burner assembly within a burner box, the burner bracket defining a cavity within which the channel of the burner frame and the burner are positionable.
A furnace comprising:
- a heat exchanger having a heat exchanger coil providing a conduit of combustion gasses having a plurality of inlets and an outlet;
- a burner box having an internal mixing chamber;
- and
- a burner assembly adapted to direct a flame into the plurality of inlets, the burner assembly including:
- a burner frame having a hollow channel formed therein, the channel being arranged upstream from and extending parallel to a longitudinal plane defined by the inlet;
- a burner arranged within an interior of the hollow channel of the burner frame, the burner being arranged in fluid communication with each of the plurality of inlets;
- and
- a burner bracket for mounting the burner assembly within the mixing chamber of the burner box, the burner bracket defining a cavity within which the channel of the burner frame and the burner are positionable.
A burner assembly for providing a flame and combustion gas to a plurality of heat exchanger inlets, comprising:
- a burner arranged in fluid communication with each of the plurality of inlets, the burner being formed from a porous material and having a curved contour;
- and
- a refractory panel positioned between an outlet of the burner and the plurality of inlets, the refractory panel including a plurality of elongated channels receivable within the plurality of inlets for communicating the flame and combustion gas thereto, each of the plurality of elongated channels being fluidly coupled to the burner, wherein a length of the plurality of elongated channels is greater than a diameter of the plurality of elongated channels.
