GAS-HEATER FOR FURNACES.

Application filed September 17, 1913.

To all whom it may concern:

Be it known that I, FELIX KORN, a citizen of the United States, and a resident of F anwood, in the county of Union and State of New Jersey, have invented a new and Improved Gas-Heater for Furnaces, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a heater adapted to heat the water in a jacket surrounding the fire space of a boiler; to provide a heater and means for controlling the same to maintain at relatively small gas expenditure the initial heat produced by the heater; to provide means for more fully graduating the heat maintained in the fire space of a boiler; and to provide ring heaters having means for introducing the fuel at opposite ends thereof.

In the drawings, Figure 1 is a pictorial view showing in front elevation and in light lines a boiler of conventional type, and in heavy lines a heater constructed and arranged in conformity with the present invention applied thereto; Fig. 2 is a side elevation of the heater and parts connected therewith, the heater being shown as separated from the boiler; Fig. 3 is a top plan view of the heater shown in Fig. 2.

To equip the boiler, such as the conventional boiler 8 shown in Fig. 1, the grate bars with which said boiler is usually provided, are omitted or removed. A pedestal 9 is mounted within the shell of the boiler 8. The pedestal 9 is provided to support the base 10 of a burner having a series of pipes or tubes 11 extending therefrom to spread the flame area of the burner. The burner having the base 10 and tubes 11 is of conventional form and construction. The base 10 has interior compartments, each of which is supplied by one of the feed pipes 12, 13 and 14.

In arranging my heater in the fire-space of a furnace or boiler, care is exercised that the base 10 rests in approximately the same plane as that usually occupied by the grate bars of the conventional boiler, which have been either removed or omitted.

The pipes 12, 13 and 14.- are supplied with Specification of Letters Patent.

gas from the lower supply main 15. The flow of gas into said feed pipes is regulated by manipulating cocks 16 17 and 18, respectively.

Circumvallating the tubes 11 and disposed in a horizontal plane substantially coincident with the outermost of said tubes s the lower ring 19. Said ring is disposed in the fire-box below the upper ring 20. The rings 19 and 20 are substantially equal in diameter, and each has a series of perforations 21 and 22, respectively, formed therein and in the outer wall thereof, as best seen in Fig. 2 of the drawings. The upper ring 20 is also provided with a number of scattered perforations 23 disposed at substantially the crown of said ring. The two rings are employed by me to maintain the heat in the body of the water in the water-jacket 0r shell of the furnace 8, after the same has been raised to any desired temperature by the operation of the full force of the burner herein described. The crown of the fire-box with which the furnace is provided crosses above the ring 20, therefore, the flame emitted by the perforations 23 impinges or afl'ects directly the wall of the crown and the water in the jacket carried thereabove. As circumdistinguished from the ring 20, the ring 19 has a single line of perforations 21, the flames emitted therefrom spreading in a horizontal plane toward the side wall of the jacket or shell of the furnace or boiler. The flame thus emitted from both the ring 19 and the ring 20 is deflected just before reaching the wall of the jacket, by the draft of air passing upward from the fire-box. Therefore, the wall is saved from the effect of the direct impact of the flame.

The rings 19 and 20 are similar in construction, in that each is open at' both ends to receive a supply of fuel from distinct branch feed-pipes. By thus feeding the fuel into both ends of the perforated pipe or rings, the supply and consequent heat are maintained more evenly over the complete circles formed by said rings. Also, by thus feeding the gas, it will be found that the regulation of the heat or flame within said rings may be more nicely adjusted to the conditions under which the heating plant is operated.

The lower ring 19 is supplied with fuel through the branch pipes 2a and 25. The pipes 2% and 25 are supplied by cocks 26 and 27, from the branch pipe 28. The branch pipe 28 is dropped below and openly connected with the main 15 and with a loop pipe 29. The loop pipe connects the main 15 with a main 30, which supplies the fuel to the ring 20 through cocks 31 and 32 and branch pipes 33 and 341-.

As will be seen best in Fig. 1 of the drawings, the mains 15 and 30 are both connected with a supply pipe 35. The flow of the gas through the mains 15 and 30 is con trolled by manipulating cocks 36 and 37. It will be observed that approximately the same arrangement of feeding the gas or fuel from both ends of a circuit, from a common supply, is followed in the mains 15 and 30 and loop pipe 29 as outlined with reference to the rings 19 and 20. The result of this construction and arrangement of the mains and loop pipe is similar to that noted as appertaining to said rings.

It will be understood that all the cocks above described except those designated by the numerals 36 and 37 have air-mixing chambers 38, whereby the air and gas forming the burning fuel employed in connection with this heater, are mixed.

When a furnace is equipped with a burner constructed and arranged as above described, and as shown in the accompanying drawings, the operation is simplified, in that all that is necessary in starting a fire is to light one of the burners, preferably the upper ring 20. When the flame has been es tablished in the upper ring 20, the gas may be turned on by the cocks controlling the flow into the base 10, to enter the chamber through the tubes 11; the gas coming in contact with the flame in the ring 20 would ignite. Likewise, the fuel delivered into the ring 19 would ignite to establish the jets emitted from the perforations 21 therein.

The heater comprising the base 10 and the distributing tubes thereof, the ring 19 with the flames extending laterally therefrom, and the ring 20 with the jets extending 'both laterally and vertically therefrom, has a capacity preferably in excess of that required for the usual service, whereby the radiating medium-water or steammay be initially quickly heated. After the heat has been raised, the burner capacity may be reduced by manipulating the cooks 16, 17 and 18, to gradually cut out the burner having the base 10, and thereafter maintain the heat in the radiating medium with heat generated by means of the rings 19 and 20. The heat deliver (1 from said rings is most efficient, the fia 18S being directed so as to sweep the inner wall of the fire box, water-jacket, or shell of the boiler 8.

Should it be desired to still further reduce the heat, this is best accomplished by either reducing the force in the ring 19, or discontinuing its use entirely. It will be noted that by diminishing the flow of gas into said ring, at either end thereof, the residual pressure is nicely adjusted to diminish the resultant consumption. If discontinued entirely, the heat is maintained by the flame emitted from the ring 20.
