BURNERS FOR G As FIRED BoILERs original Filed Nov. 4, 194s United States Patent O BURNERS FOR GAS FIRED BOILERS Charles Howard Hook and Wallace W. Miller, Pittsburgh, Pa.
Original application November 4, 1948, Serial No. 58,242. Divided and this application March 29, 1951, Serial No. 218,206
1 Claim. (Cl. 15S- 114) This application is a division of application Serial No. 58,242, filed November 4, 1948.
This invention relates to new and useful improvements in burners for gas-tired boilers, and it is among the objects thereof to provide an improved burner which is in sections, each section having rows of burner ports closely arranged and disposed at a slight angle to prevent co-mingling of the burner flames and to expose the llames to secondary combustion air passing upward between the rows of burners.
It is a further object of the invention to provide means for distributing the gas flow in each boiler section in a manner to equalize the gas pressure underneath all of the ports of a burner section.
These and other objects of the invention will become more apparent from a consideration of the accompanying drawings, constituting a part hereof, in which like reference characters designate like parts and in which:
Figure 1 is a top plan view of a burner section embodying the principles of this invention; and,
Figure 2, a cross-sectional view taken along the line 2--2 of Figure 1.
Burners 1 are mounted by tapered fittings 2 in the venturi tube 3 connected to the gas manifold having control valves 4 with the usual air inlet 5 to provide the primary air that co-mingles with the gas flowing to the burners, the burner section itself being constituted of three ducts 6 separated by air spaces 7 and having burner ports or jet openings 8 and 9, there being two rows of ports for each flow duct. The center duct of the burner section and the inside portion of the outer ducts are free of burner ports at the center thereof immediately above the tapered tting 2, and baille plates, shown in dotted lines at 10, Figure 1, and shown in full lines in Fig. 2, are attached to the burner casting by screws 11 to cause the gas to be distributed as it comes up through the tting 2 to the outer ducts 6 to effect a balance of gas pressure underneath all of the burner ports.
The burner ports, as shown in Fig. 2, are drilled at a slight angle to the vertical so that the burner llames are divergent between the rows of ports over each of the ducts 6 and the burner ames tend to converge above the space 7 between each of the burner tube sections.
,. ICC
The reason for this arrangement is to prevent the llames from co-mingling which would be less eicient because of the absence of oxygen, the llames being kept separated, `as shown in Fig. 2, by a column of air rising upward through the space 7 between the duct sections 6. This arrangement of the burner llames permits closer arrangement of the burner ports, and the increased number of burner rows reduces the height of the flame and permits closer arrangement of the burners to the water tube sections.
The larger number of burner ports, and the low flame that allows proximity of the boiler tubes to the flame all function to reduce the floor temperature below the burner, which is but a fraction of the temperature of conventional gas red boilers, thus making the boiler safe for use on floors of inammable material without any danger whatsoever.
Although one embodiment of the invention has been herein illustrated and described, it will be apparent to those skilled in the art that Various modifications may be made in the details of construction without departing from the principles herein set forth.
I claim:
A burner for gas-fired furnaces of the type having rows of boiler tubes spaced immediately above the burner structure comprising burner heads of a plurality of parallel duct sections with air spaces therebetween and constituting an integral casting, said sections being connected by a cross web having an inlet neck portion centrally of the ends and sides thereof forming a gas inlet and distributing chamber communicating with said ducts, a venturi tube adapted to lead fuel from a gas manifold and connected to said inlet neck portion at the other end thereof, each of said burner ducts having pairs of rows of closely spaced jet openings except in the area above the gas distributing chamber with the openings of adjacent rows staggered and divergently inclined at a slight angle, said area being imperforate and baille plates disposed in said gas inlet and distributing chamber, said plates substantially extending from the center duct to the outer walls of the outside ducts of the burner heads.
