Specification o f-Letters Patent.
Patented Nov. 25, 1913.
Application filed November 30, 1131a Serial No. 784,260.
To all whom it may concern:
Be it'known that I, FnEDE'RIo C. CHAD- BORN, citizen' of the United States. of America,residing at 221 Third street, Newburgh, in the county of Orange, State of ew York, have invented certain new and useful Improvements in Burners, of which the following'is a specification.
My invention relatesto improvements in burners for gaseous fuels.
The primary object of the invention is to provide an improved form of burner wherein a mixture consisting'of gas and a preponderating amount of air will burn with an intensely hot flame.
A further object of the invention is to simplify and improve the structure-of a burner of this type whereby the cost of producing the same and the facility with which the burner may be constructed, will be minimized.
Figure 1 is a vertical longitudinal sectionof the preferred form of burner, certain parts being shown in elevation; F ig.'2 is an elevational View partly in section of a modified form of burner; and Fig. 3 is a similar view of a modified form of disk more fully hereinafter referred to.
My improved form of burner is especially designed to be used as a Water heater and is adapted to be placedunder boilers for the purpose of quickly and economically heating the Water therein. I desire it to be understood however, that the application of the invention is not limited to this use and that the burner may be employed prac tically in any connection where an intensely hot flame-is required.
I have found in practice that the more thoroughly the air. and gas are admixed, and the better the preheating of such mixture,
1 and 15 respectively,
the more intensely hot paragraph immediately preceding, I provide in the structure of my burner, a suitable casing designated generally as 10, the lower portion of which is provided with air admission openings 11 of considerable area. The casing 10.is supported by a standard or pedestal 12 into the base 13 of which the fuel supply pipe 14 opens. 15 is the gas nozzle. I I
All that portion of the interior casing above the air and gas admission openings 11 may be considered to be the mixing chamber and'has been designated generally by the numeral 16.
The air and gas naturally cominingle upon entering the mixing chamber 16, but to provide for a. further admixture of the entering air and gas, I may employ a mixing device which consists of a series of wings 17, the outer. edge of each presenting an ogee curve and the lower edge portion of each wing being threaded at 17 to engage threads 10 formed at approximately the median part of the inner wall of the casing 10. The extreme lower edges 17 of the mixing device are practically knife edges so as to minimize the possibility of their acting as baflies or retarders to the upward flow of the gaseous mixture. The upper part 10" ofthe casing is preferably of substantially globular formation, and the wings 17 at this globular portion are correspondingly enlargcd as to diameter. The air and gas mixture at this point is permitted to expand considerably owing to the. globular formation of the part 10 of the casing.
Suitably attached to, or formed integrally with the upper edge offthe globular part- 10 of the casing is a sleeve like extension 18 which becomes highly heated when the air and gas mixture is ignited, the heat from the extension 18 being conducted down through the casing 10. The walls of this extension are preferably somewhat inclined for a purpose to be described, the. extension to a certain extent forming a truncated cone.
Resting upon the upper ends or edges of the mixing device 17 is a suitably shaped disk19 which serves to spread the flames wall of the extension 18, and which disk in ,combination with the extension 18 and the mixer 17 also assists in heating the mixture of gasand air to be ignited.
The operation of the form of invention above described is as follows: Assuming the gas from a source not shown to be flowing through the pipe 14 and out at the nozzle 15, air in considerable quantities will be drawn in through the openings 11. The air and gas will commingle in the lower partof the casing 10 and as this mixture rises in the mixing chamber-16 it will flow against the staggered wings 17 where it will be sub ected to further mixing and agitation. Assuming now that a flame be applied at the opening 20 between theinner edge of the extension 18 and the periphery of the disk 19, the gas and air mixture will be ignited and will burn as a flame of substantially round or annular shape. The flame will act against practically all parts of the inner surface of the extension 18 and this heat will be conducted down through the casing 10 and the radiation from the casing 10 will be sufficiently intense to heat to a very high degree the air and gas mixture'almostat the moment of its entrance into the mixing chamber 16. The flame will also have a tendency to heat to a very substantial degree the disk 19 and the mixer 17 so that the latter will also assist in heating the air and gas m xture in'its upward passage through the mixing chamber.
In the modified form of the invention, the
construction and operation are substantiallyanalo-gous to those of the preferred form. 10 is the burner casing, 11 the air admission orifices, 12 the pedestal, 13 the base, 14 the gas admission pipe, 15 the gas admission nipple, 17 -the mixer, and l8 is a slightly modified form of extension which is provided with a plurality of holes near its lower edge, each of hich holes is adapted to receiveone end'% a pipe or tube 21, the lower end 21 of which is 0 en to atmosphere, these several pipes being esigned to supply air to the ,combustion space in addition to that drawn in through the air admission openings 11. In other respects the modified form of invention .is analogous to the preferred form and no further description of such modified form-is thought to be required.
In Fig. 3 I have shown a modified form of disk or flame spreader, 19 being the disk proper and having projecting from its upper face a series of pins or what may be termed heat conductors 22. These pins are spaced apart so as to withdraw from the flame a greater or less amount. of heat which is transmitted to the wings 17 and by them conducted down into the space which forms the mixing chamber. In the forms shown in Figs- 1 and 2, the disk 19 is substantially of a sharp conical formation and acts practically in the same manner as does the modified form illustrated in Fig. 3.
I have found in practice that a burner of the 'type herein described may be placed under a boiler, the space being practically dead so far as the circulation of oxygen is concerned, and an intensely hot flame will be sustained in the burner as long as the supply of fuel is continued. This result is no doubt in part due to the fact that by the intense heating action of the several parts which participate in this function, the entermg air and gas mixture is highly agitated and heated, and also due in part to the fact that by providing air admission 0 enings considerably greater in area than t e fuel admission opening, a sufiicient quantity of oxygen is carried up to the point of ignition to sustain the flame and to keep a constant very strong draft in motion.
I claim:
