GAS BURNER.
' Application filed June 10,
This invention relates to improvements in gas burners and more particularly to a type of burner in which the gas and the alr are not mixeduntil after the ejection of the gas from the nozzle, and arranged so as to supply both air and gas under pressure to the mixing area, whereby a maximum temperature may be obtained with a minimum pressure, and particularly adapted for use in connection with blast furnaces for reducing ore.
Other objects of invention will appear in the specification hereinafter following,- in which a preferred form of device is described.
I. have shown said preferred form of device in the accompanying drawing, in which:
Fig. 1 is a side elevation of the assembled gas burner.
Fig. 2 is a sectional elevation of the same.
Fig. 8 is a rear end view thereof.
Fig. 4 is a rear view of the body closure for supporting thenozzle in operative position.
Fig. 5 is a side view of the same; and
Fig. 6 is a rear view of a special form of cap adapted for use in my burner.
Briefly described, my improvements consist in the provision of a burner body as at B in the form of an elbow with a cap C attached to the horizontal portion 1 thereof, and an air supply pipe P attached to the vertical portion 2. A gas supply tube Gr is centrally mounted in the body B and is provided with a nozzle N and an inlet I. Said tube is suitably supported in an end closure E by means of a ring R, as shown in Fig. 2.
The portion 1 of the body B is externally threaded to receive a cylindrical portion 3 of cap G, and said cap has a conical portion 4 of cylindrical cross section forwardly of the portion 3 thereof, with a central opening 0 in its end, and a plurality of spirally or angularly formed ribs r, 7. etc, internally thereof as shown in Fig. 2. Axplurality o't lugs 55, 5, may be provided on theexterior of cap C whereby said cap may be threaded onto and removed from the body B.
The gas supply tube G is centrally supported in the body B and is provided with an enlarged portion 6 within which is a gas expansion chamber g. Forwardly of said expension chamber is a tubular nozzle N having a gas passage 7 therein of smaller area than the chamber 9. Said nozzle extends substantially forwardly into the air chamber 2 within the body B, to which air is supplied 1926'. Serial No. 115,052.
through the vertical passage 8 in the portion 2 of said body from pipe P. Member G also has a right angularly formed inlet pipe I The rear wall 9 of body B is provided with athreaded opening into which an end closing member E is threaded, tor the purpose of detachably supporting the member Gin operative position in the body B. Said member ID has threads 10 on the periphery of the flange portion 11 thereof, for attaching the same in positionin the body, and the flange portion 11 is provided with lugs 12, 12 whereby the same may be attached to and detached from said body. The member E has an extended boss 13 with a bore 14 extending longitudinally therethrough to receive a portion 15 of member G, and the outer end of said boss abuts the shoulder 16 formed on the large portion 6 of the member G. The adjacent portions of the boss 13 and the portion 6 of member G are externally threaded to receive an internally threaded ring R for holding the member G in position on the member E and centrally disposed in the member B.
The nozzle N is extended forwardly into the cap C for a suflicient distance so that the gas ejected from said nozzle will impinge on the inwardly projecting ribs 9", :1", etc., and cause a whirling or eddying of the gas as the same is ected from the opening 0 of the cap C, also the air fronrthe air chamber rlfwhichv is admitted under pressure from pipe P will mix with the internally oi the cap C and will be set in motion by means of the ribs 7, thus effecting a more perfect mixture of the gas and air than would otherwise be possible.
Either artificial or natural gas may be employed for use as a tuel in mv burner, and relatively low gas pressures may be used for ecting the gas ii om the nozzle N, due to the fact that the whirling of the gas and air during the mixing process forwardly of the nozzle serves to create a partial vacuum in front of the nozzle and thus produce sufficient sucti on to induce the flow of gas from the nozzle when. the pressure of the gas is very low.
It will'be obvious that by increasing the air pressure in the chamber A the suction of the gas from the nozzle N will be correspond ingly increased so as to overcome any deficiency in pressure in the natural or artificial pressure of the gas.
It will be understood that while I have shown only a prferr ed form (if my invention for the uses stated, the same may be modified to meet other uses Without departing from the "spinner i'ny'iny'eiitio'n or enlarging'the scope thereof beyond that of tli'e'appei'ide'd' claims. What I claim is: i y l. A gas burner comprising a body member having a cylindrical air chamber therein,
an air inlet thereto, a cylindrical cap detachably held on saidbody m'ember and provided with a 'fi'usto-conical end port-ion and 'acen tral' opening therein, a plurality of internally formed spiralribs on said'frustomonicaliportion, an end closure in the rear Wallof "said body detachably held therein, a 1 gas *supply tube detacliably heldon said closure and pro- 'vided with a nozzle centrally positioned in said 'air' chamber, said gas supply tube having an intermediate expansion chamber rearwardly of said nozzle, and a gas inlet for supplying gas to said expansion cha nber.
2. Agas burnerhavin'g' abody'vvith an air chamber therein for'receivi'n gair under-presi',6e0,74s I su e, an air inlet communicating therewith,
and an outlet,a cap encompassing said outlet and provided With a conical end portlon havj ing central opening th rein forming anoutlet for the air and gas, a plurality of internally formed spiral ribs on the conical portion of said cap for impartinga whirling motion to-thei'i-iixtureof gas and air. a gas supply tube centrally mounted in saidbody and axia threaded opening in the rearwall thereof aliwne-d' vith' the opening in said cap, a closure 'detachably held inisaid opening and provided witha central bore for I'QCGlVlDQ'SiLlCl sup- .ply tube, anda threaded rin g embracing adj acent portions of saidclosure andsaid tube for detachably supporting said tube in posit-ion.
