COMBINATION GAS BURNER .AND OMBUSTION GHAIlVlIBlBh` Application filed November 28, 19 21. Serial No. 518,:312.
This invention relates to a combination 'gas-burner and combustion chamber.
An object of my invention is to provide means whereby heat of combustion 'generated by the burning of gas in a combustion chamber may be confined and collected by a wall of 'the combustion chamber and thereafter radiated from the wall to a, body to be heated. A I
Another object is to provide a combustion chamber having a wall formed of heat resisting material provided With a series of protuberances adaptcd to retard and confine' heat, and also adapted to radiate heat to lsi surface to be heated spaced from the wa i Another object is to provide a combined combustion chamber and gas burner in which the combustion chamber is so constructed and the burner so arranged as to atford a proper proporticn and mixture of gas and primary air to insure complete combustion within the combustion chamber so as to obviate the cooling action incident to the introduction of an 'excess of primary or secondary air into the combustion chamber, which coupled with the collection and the radiation of the heat of 'combustion as above referred to produces a heater of high efl'iciency and economy of gas Consumption.
Another object is to provide a combined combustion chamber and gas burner of simple construction in which the parte may be readily assembled and which is adaptcd to be installed in a fire-box to heat the walls thereof by radiation rather than by convective heat as ordinarily practiced in boiler Operations. V
With the foregoing objects in view and such other objects and advantages as may subsequently appear my invention resides in the parts and in the combinaticn and Construction of the parte hereinafter more fully described and claimed and illustrated in the accompanying drawings in which Fig. 1 is a view o a combined combustion chamber and gas burner as seen in vertical section;
Fig. 2 is a fragmentary horizontal section and plan view as seen on the line 2-2 of Fig. 1;
Fig. 3 is a detailed vertical section as seen on the line 3-3 of Fig. 2;
Fig. 4 is a detail in perspective of the heater unit with parts removed;
' Fig. 5 is a detail in perspective illustrat- .ing a' modified form of the radiating wall of the combustion chamber;
Figure 6 ,is a plan view of the structure shown in Figure l.
Referring to the drawings more specifically 7 indicates a 'body' formed of refrac tory material comprisng a base portion 8 and an upwardly eXtending wall 9 adaptcd to constitute the back-Wall of a combustion chamber 10; the wall 9 being fol-med with a shoulder ll-spaced above the plane of the lower face of the base portion 8. The uppcr 'end portion of the wall' 9 is turned horizontally to form a top wall 12, the outer edge of which is serrated to form a series of vents 13. The inner surface of the wall 9 is provided with a series of pro'jections 14 which serve as baffles and are adapted to be'heated to incandescence so as to constitute heat radiating elements.. The body 7 is preferably designed to be seated on a grate 15 and arranged with its inner face proximate to a wall or surface 16 to be heated, with the projections 14 extending close to the surface 16 so that when the projections are highly heated they will act to radiate heat to the surface 16. The walls 9 and 16 form two sides of the combustion chamber 10, the ends of which are closed by suitable walls 17, and the top. of which is formed by the serrated wall 12 which abuts at its edge against the surface 16 so that the vents 13 will serve as outlets for the discharge of products of combustion from chamber 10. V
Arranged on the grate 15 below the shoulder 11 is a tubular gas burner 18 provided with a series of upwardly opening burner nozzles 19 and spaced above the burner 18 is a horizontal wall 20 formed with open ings 21 arranged above and spaced from the burner n0zzles 19 which openings constitute mixing throats. The wall 20 is formed of refractory' material and sets against the shoulder 11 to project horizontally from the inner face of the upwardly extending wall 9 with the openina's 21 arranged adjacent to the inner surface of the wall 9; the horizontal wall 20 being here shown as supported -on standards 22 formed on the burner '18. It is intended that the only inlets to the combustion chamber 10 comprise the openings 21 and accordingl v the wall 20 is designed to extend between the wall 9 and the surface 16 throughout the length of the wall 9 and between the 25 to provide air .of the burner.
In the operationof the nventon gas s 4 'delivered to the burner froni any suitable ajsource and discharged throughnozzles 19 and causedto pass upwardly through the .openings 21 intothe-'combistion' chamber 10 where it is ignited; the flow of gas 'through the openings. 21 acting to draw air' from 'beneath the burner upwardly around the`sides thereof and into the openings 21 where the gas and' air are mixed to rovide the proper mix'ture to support' com ustion :of the' gas which is designed to take place adj acent the' wa1l20 and form an intense` heat in the lower portion of the combustion chamber. The c'onvective heat rising in the. combustion chamber will be baflied and. re`-` .tarded the projections 14. so that the latter will' e highly heated preferably to in- I candescence so that the ma or portion of .the
heat generated in the'combustion 'chamber will be absorbed by the refractory material foriing ,the body 9 and projections 14: so as to. reduce the waste heat passing through the vents 18 inthe products of combustion toa minimum. The heat collected by the projections 14 and wall 9 is largely radiated to the w'all 16. 'In order to inhibit the loss 'of heat through the body 9 the latter may be cov ered with a suitable heat insulat-ion 29 as shown in Fig. 1 which may comprise` 'a covering of asbestos or other suitable material. i
By means of my invention a high eiiiciency in heating eflect relative to gas Consumption is obtainecl as the heat of combustion will be confined in the ecombustion chamber 10 until the largest portion possible is absorbed by the' surface to be heated.
I claim:
1. 'In a combination gas burner and comi 'bustion chamber, .an' upwardly' extending ;said Wall and' ornied with a series of spaced passages along 'each' 'side gas burner located below said horizontal -wall and having a series `of`gas orifices,
