Abstract

One aspect of this disclosure provides a finger baffle for a heating furnace. This embodiment includes an elongated support plate having a length, and at least one finger baffle extending outwardly and in a vertically oriented direction from the elongated support plate. The at least one finger baffle has a width that extends along the length of the elongated support plate. The finger baffle may be employed in a high-efficiency gas furnace.

First claim

What is claimed is:

1. A method of fabricating a finger baffle for a heating furnace, comprising:
forming an elongated support plate having a length from sheet metal;
forming spaced apart finger baffles from said elongated support plate; and
bending said finger baffles such that each of said finger baffles extend outwardly and in a vertically oriented direction from said elongated support plate, each of said finger baffles having a width that extends along a length of said elongated support plate and a length that extends from said elongated support plate to a pre-determined hot spot of a heating chamber, wherein said finger baffles are placed within a primary heating zone of the heating furnace to guide air to the pre-determined hot spot located proximate an outlet end of the heating chamber.

2. The method of claim 1 , wherein said vertically orientation of each of said finger baffles ranges from about 70 degrees away from said elongated support plate to about 90 degrees with respect to said elongated support plate.

3. The method of claim 2 , wherein each of said finger baffles is oriented at an angle of 90 degrees with respect to said elongated support plate.

4. The method of claim 1 , including further bending said elongated body to form an angled connecting plate integrally formed with and extending downwardly from said elongated support plate.

5. The method of claim 4 , wherein said connecting plate extends downwardly from said elongated support plate at a 90 degree angle and extends along said length of said elongated support plate.
