Application April 1, 1946, Serial No. 658,826

3 Claims. 1

This invention relates to a gas burner. y One object of the invention is to provide a gas burner unit which may be readily installed in household furnaces originally adapted for burn- I ing gas or other types of fuel. Another object is to provide a burner which may be used in water heaters, floor furnaces, and various types of house-heating units. Another object is to provide a burner unit which is adaptable for use with various kinds of gas fuels including natural gas, manufactured gas, or liquified fuel gases. Another object is to provide a burner in which the combustible mixture is thoroughly mixed and preheated before ignition. A further object is to provide a gas burning unit which may be readily adjusted for heat outputs varying over a wide range. A still further object is to provide a gas burner which operates with a minimum amount of noise. 'Ihese and other objects are attained by our invention which will be understood from thefollowing description, reference being made to the accompanying drawings in which:

Fig. ,1 is a cross-sectional view of our burner unit as applied to the re-box of a house-heating furnace;

Fig. 2 is a top 'elevational view of the burner with parts broken away to better show the construction;

Fig. 3 is a cross-sectional view taken on the line 3-3 of Fig. 1.

Referring to the drawings, our burner consists of a vertically disposed body member II and a horizontally disposed mixing tube I2. The body member consists generally of an annular member I3 having an outer wall I4 and an inner wall I5, these being preferably cylindrical in shape and closed by a bottom plate I6. The annular space I1 serves as a preheating and mixing chamber for the gas and primary air which is introduced into this space through the mixing tube I2 which is connected through the outer wal7 I4. The annular opening I1A is restricted b an annular disk 4I on the top of the annular member I3 to better direct the flow of premixed gas and air. The outer wall I4 is provided in its upper portion with an outside iiange IB by which the body member II is supported inside the re-box F on an annular horizontal partition member I9 attached to the inside wall of the fire-box and extending inwardly to the ange I8. The ilange I8 is provided with openings 20 disposed around the body member outer wall I4 and these openings serve for the entrance of secondary air, there being a coaxial cylindrical collar 2I attached to the upper side of the ilange I8 and extending upwardly to the top of the annular member I3, the space between the collar 2I and the outer wall I4 serving as a conduit to carry the secondary air to the outside of the burning mass of combustible mixture as it leaves the muoth of the annular space I1. The volume of secondary air which may enter this conduit is controlled by means of the movable ange 22 adjustably positioned on the outer wall I4 by thumb screws 23, the distance between the movable ilange 22 and the openings 20 in the flange I3 determining the amount of secondary air.

The mixing tube I2 which adjoints the body member for delivery of the primary air and gas to the annular space I1 consists of a needle valve 24 having `an adjustable needle 25 acting in an apertured tapered seat 26 within the valve body 21. The valve body 21 is connected to the gas pipe line 28 which is supplied with a hand-actuated valve 29. The valve body 21 extends into a primary mixing chamber 30 which is provided with openings 3| for the entrance of air, the control of the amount of air being eiected by a disk 32 conveniently mounted on the hub 33 which is threadedly engaged on the outside of the valve body 21 so that the distance between the disk 32 and the openings 3I for the admission of primary air may be regulated by turning the hub 33 on the, threads of the valve body. The gas from the nozzle 34 of the needle valve 24 mixes with the aspirated air brought in through the openings 3I and is .further mixed -in the mixing 'tube I2 and carried therein to the annular space I1 of the body member. A pilot burner 35 is provided inside the inner wall of the annular member I3, and is positioned adjacent the top of the main burner, the pilot being connected by a pipe line 36 to the source of gas fuel.

A baille disk 31 is mounted on a supporting rod or pipe which is afxed to a foot-piece 39 placed upon the iioor beneath the burner, the supporting rod 38 conveniently consisting of a lower portion 38B joined to an upper portion 38A by means of a pipe coupling 43 whose lower end'rests on the wall I6, a lock nut 42 being provided below the wall I6 on the rod or pipe 38B for securing it to the body member II. The

height of the bane disk 31 may be varied by substituting a rod or pipe ofI the desired length through the threaded connection with the coupling 43.

The burner is adapted to use any type of gaseous fuel and the amount of primary and secondary air relative to the amount of gas may be adjusted by means of the adjustable controls or shutters arranged in front of the air openings. An important feature of our improved gas burner is the introduction of the secondary air at the outside of the flame as it leaves the burner. This arrangement is advantageous in producing complete and uniform combustion and in providing an outer blanket of air in the zone immediately about and above the burner which provides protection to the fire-box and gives better distribution of heat. This also gives a ilame which is free from noise which is a feature of some importance in household furnaces. The height of the baille disk may be varied to provide the distribution of the flame for the most effective heating dependent upon the size of the fire-box, the chimney draft, etc. The amount of gas which enters the burner may be controlled by wellv known thermostat valve controls and because of the arrangement for introducing secondary air, the quantity of gas which may be completely burned with maximum eiciency may be varied over a wide range without further adjustment of the air intake ports.

We claim: -f
