Ultra low NOX insulating burner without collar

Abstract

A burner comprising is provided including a burner tube formed at least partially from a first material having a plurality of openings. The plurality of openings are sized to allow a fluid but not particles of debris contained within the fluid to flow there through. A flange extends outwardly from a portion of the burner tube and is receivable within an embossment formed in an adjacent component. The flange is formed from a second material having a plurality of openings such that heat transfer between the flange and the adjacent component is limited.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. provisional patent application Ser. No. 62 / 190,576 filed Jul. 9, 2015, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]The subject matter disclosed herein relates to heating systems. More specifically, the subject disclosure relates to burners for residential and commercial heating systems.[0003]Heating systems, in particular furnaces, include one or more burners for combusting a fuel such as natural gas. Hot flue gas from the combustion of the fuel proceeds from the burner and through a heat exchanger. The hot flue gas transfers thermal energy to the heat exchanger, from which the thermal energy is then dissipated by a flow of air driven across the heat exchanger by, for example, a blower.[0004]A typical prior art construction is shown in FIG. 1. A burner 100 is located external to a heat exchanger 102. The burner 100, often referred to as an inshot burner 100, ...

AI Technical Summary

Benefits of technology

The patent describes a burner design that includes a flange with openings that allow fluid to flow through without particles of debris. The flange is positioned at the outlet end of the burner tube and is made from a different material than the burner tube. The flange can be removably or fixedly coupled to the burner tube. The technical effect of this design is that it allows for limited heat transfer between the flange and the adjacent component, which can improve the efficiency of the burner.

Problems solved by technology

Due to the highly conductive nature of the flange, the heat of the flame is transferred to the partition plate via the flanges, resulting in damage and / or deformation of the partition plate.
