Abstract
A refractory panel for a heat exchanger is provided having a body including a first planar surface having a plurality of refractory openings formed therein. A sidewall is arranged about a periphery of at least one of the plurality of refractory openings. The sidewall extends outwardly from the first planar surface and is configured to extend through an adjacent component into an inlet of a heat exchanger coil.
Claims14
A refractory panel for a burner assembly, comprising:
- a body including a first planar surface having a plurality of refractory openings formed therein, wherein each of the plurality of refractory openings is positionable in axial alignment with and downstream from a burner outlet, the body being receivable within an internal cavity of an inner box of the burner assembly such that a surface of the inner box and the first planar surface are in overlapping arrangement;
- and
- a sidewall arranged about a periphery of at least one of the plurality of refractory openings, the sidewall extending outwardly from the first planar surface and being configured to extend through an opening formed in the surface of the inner box and into an inlet of heat exchanger coil when the body is installed within the internal cavity;
- and
- wherein a portion of the sidewall configured to extend into an inlet of the heat exchanger coil bends inwardly towards a center of the opening.
2 more elements
A furnace comprising:
- a heat exchanger including a plurality of coils;
- and
- a burner assembly including:
- one or more burners disposed at and substantially aligned with one or more burner openings of the heat exchanger;
- a partition plate including one or more partition openings substantially aligned with the one or more burner openings of the heat exchanger;
- an inner box including one or more cell openings substantially aligned with the one or more partition openings, wherein an inlet end of one or more of the heat exchanger coils is arranged in contact with a surface of the inner box, the inner box defining a cavity;
- and
- a refractory panel arranged downstream from the one or more burners generally between the partition plate and the inner box, within the cavity of the inner box, the refractory panel including one or more refractory openings substantially axially aligned with the one or more burners, the one or more partition openings, and the one or more cell openings, wherein a sidewall arranged about a periphery of the one or more refractory openings extends through an adjacent cell opening formed in the inner box into a corresponding coil of the plurality of coils, wherein a distal end of the sidewall includes a feature;
- and
- wherein a portion of the sidewall configured to extend into an inlet of the heat exchanger coil bends inwardly towards a center of the opening.
