GAS-BURNER FOR FURNACES.
Specification of Letters Patent.
Patented Apr. 9, 1912.
To all whom it may concern:
Be it known that I, EDVARD H. KEssEL- MAN, a citizen of the United States, residing at Butler, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Gasliurners for Furnaces, of which the following is a specification.
The object of my invention is to provide a simple and cheap form of gas burner for steam boiler and other furnaces, designed for the use of natural gas or other gaseous fuel in the place of coal and adapted for use in furnaces as alreadyconstructed.
It relates to that form of gas burner in which air and gas pipes are arranged within the fire box and above the grate bars, and my invention consists in the novel. construction and arrangement of the burner in combination with the associated parts of the furnace, whereby gaseous fuel may be employed in ordinary boiler furnaces wit-h practically no alteration of or injury to the furnace and with only such slight adapta- I tion as may be easily and quickly made, while at the same time the burner is made to give a very high heating efficiency with most economical results and without burning out or destroying any of the parts.
Figure 1. represents a perspective view,
partly broken away and showing my burner applied to a steam boiler furnace of ordinary form. Fig. 2. is a vertical cross section through the fire box and, Fig. 3. is a longitudinal section through one set of the burner pipes.
In the drawing A represents the fire box and B the grate bars of an ordinary steam boiler furnace.
C C are two parallel pipes of about four inches diameter extending longitudinally along each side of the fire box just above the grate bars. These pipes have a series of short mixing tubes a along their length which project upwardly and inwardly.
D D are smaller pipes for gas arranged within the larger pipes O and having relatively small nozzles I) along their length which are arranged concentrically in alinement with the mixing tubes (1. The larger pipes C are closed at both ends and are located entirely within the fire box but have at the bottom throughout their length slitted openings 0 extending longitudinally along their lower sides.
On top of the grate bars B of the furnace a fire resisting partition of fire-brick E is laid extending all the way across the fire box and completely separating the air space in the ash pit from the fire box above, except as hereinafter provided. This refractory partition of fire brick completely in closes the large pipes C and also extends beyond and partially incloses and protects the upper outlet ends of the mixing tubes (2 of the burner forming a raised projection of fire brick within the angle at each side of the fire box between the partition E and the side walls of the furnace. The lower sides of the pipes C containing the slitted openings 0 are open to the space below the grate bars, the fire brick partition E being interrupted at thesepoints or having registering holes therewith.
The inner gas pipes D extend through the front wall of the fire box and connect with a horizontal supply pipe F through which the natural gas, or other form of fuel, is int'roduced under pressure.
The operation of my invention is as follows: When the gas. entering pipe D D, issues through the various nozzles b, it draws in air from the ash pit through the openings 4' in the bottoms of tubes C C which air mixes with the gas in the mixing tubes a in proper proportion for complete combustion and the mixture being ignited, the two series of jets of flame intersect each other, by reason of the inward inclination of the nozzles, at a point. a: just below the boiler and spread beneath the under surface of the same with an intensified heat and combustion, in which one series of jets of flame cooperates with the other with a mutual action to thoroughly mix and burn all combustible combustion and avoiding the chilling of the fire box by too much air from the ash pit. Secondly, it embeds and completely protects all the burner pipes, nozzles and mixing tubes against the destructive influence of the great heat, and third, it shuts off and pre-' vents loss of heat by downward radiation from the fire box. Not only are these results obtained, but my burner is applicable to any ordinary boiler furnace with scarcely any alteration of or injury to the same, as the horizontal fire brick partition and burner pipes may be quickly and conveniently placed right on top'of the grate bars, and the installation of the burner therefore involves no radical change.
In carrying out my invention l may employ more than two burner pipes-if desired, and may otherwise modifyor alter the construction of the parts Within the scope of the claims.
' I claim:
1. A gas burning furnace, comprising two parallel and horizontal outer pi es with outlet mixing tubes along the upper sides, the tubes of the two-pipes being inclined inwardly to- Ward each other to make an mtersection of flame, said pipes being closed at.both ends and having along their bottom sides air inlet openings, and gas pipes arranged within the outer pipes and having, nozzles along their sides alined with the mixing tubes of the outer pipe and an inclosing bed of fire resisting material surrounding the pipes and inclosing its burner outlets and extending entirely across the space between the pipes.
2. The combination with a furnace fire r box and gratebars; of agas burner consisting of horizontal air pipes and inner gas pipes laid parallel with each other and just above the grate bars and having inwardly directed nozzles and a fire resisting bed laid'upon the grate bars and completely enveloping the along the lines of its bottom opening and along the line of the burner outlets.
In testimony whereof I aflix my signature I in presence of two witnesses. A EDWARD H. KESSELMAN. Witnesses:
