GAS-GENERATING BURNER.

Application filed February 7, 1922. Serial No. 534,661.

or other heat providing agencies, whereby the use of coal and wood forfuel is dis pensed with, the required heat being supplied by the ignitionof the gas generated by the'burner. j

Another object of the invention is to provide a burnerfor kerosene oil in whichthe said oil is superheated by the flame of the burner for generation into gas, means being provided for receiving and collecting the vaporized gases passing beyond the burnerjets whereby they may be stored for lighting purposes or for return to the burner 1 An additional object is to provide a gas 39 generating burner of generally improved construction and design and embodying novel means for the removal of carbon deposit from the burner pipes without requiring the taking apart of the burner.

Various other objects and advantages of the invention will become apparent during the following description.

Describing the invention in detail, 10 des-- 1 ignates a furnace to which the invention 1s applled, the latter havmgthe generating burner overlying the grate bar 11 and supplied with kerosene oil from a supply tank 12. This tank is suitably supported at a convenient distance from the furnace and is connected to the burner by a pipeeline 13 which penetrates the ash-pit of the furnace in the manner shown. A second pipe-line 14 also penetrates the ash pit and connects with a storage tank 15. Each pipe-line is curved, as at 16, in the are of a circle the center of which coincides with the hinge of the ash-pit door 17 thru one of the draft openings of which the said pipe extends. Hence, the door may swing outwardly along the curved portions of the pipes when opened.

The generating burner comprises a plurality of horizontal pipes or tubes 18 arranged in spaced parallel relation with their opposite ends closed by plugs 19. These tubes are connected, one to the other, at relatively opposite ends'to provide alternating loops in which the kerosene is heated. The kerosene is conducted to the inlet end 20 of the generating loops thru a pipe 21 which extends inwardly toward the center of the burner, as shown in'Figure 4, and connects with a vertical pipe 22. Pipe 22 extends downwardly thru the grate and is coupled to pipe line 13, as shown in Figure 3. 'The burner or flame pipe 23 of the de-' vice is arranged crosswise of generating tubes 18 and below the same, being connected by horizontal 24 and vertical pipe 25 to the outlet end 26' of the tubes. The

opposite end of the flame pipe is coupled opposite end of pipe 30 is connected an outand mixtur'e causes a flame aboveeach.

let pipe 31, similar to member 21 and coupled to pipe line 16 as shown in Figures 2 and 3.

In using the burner the oil from tank 12 is conducted thru the various tubes of the burner and is ignited above jets 32 of the burner pipe 23, at which points the oil mixes with air entering thru the ash pit. and open grate of the furnace. As the kerosene passes thru tubes 18 on its way to jets 32 it is heated and converted into gas by the burning gases below the tubes and hence readily mixes with air at the valves when sprayed in vaporized or gaseous form from the jet. Any surplus gas passing beyond the jets is conducted thru pipe line 16 to the gas storage tank 15 where it accumulates under pressure. As this tank is in communication with the burner pipe the reserved gases are free to return under back pressure to the jets, consequently, insuring a steady feed thru the flame jets. The ignition of the air jet and since tubes 18 pass thru the flames it will be seen that the oil is preheated and converted into before reaching the jets.

Each jet has a needle-valve 33 for regulating the flow of gas thru the burner pipe. The valve is enclosed in a casing 34 and projects into the ash pit of the furnace.

as shown in Figures 2 and 3, so that handle '35 may be conveniently reached for making adjustments. To start the burner gas may be forced thru jets 32 for ignition by means of pump 36 which expels the gases from the tank. To the tank may be connected a distributing line '37 having a re ulating valve 38. The gas supplied thru line 37 may be used for illumination or other purposes. The tank may be drained thru a drain-cock 39.

Straddling tubes 18 is a removable bracket 40 having clips 1 at opposite ends for gripping certain of the tubes and flame spreading discs 42 are swiveled at 43 of the. bracket for tilting movement. The discs are above the tubes and permit deflection of the flames in the desired direction.

Figures 7 and 8 show the interior construction of the burner tubes which are provided, in the present instance with a longitudinally extending core 44: of polygonal cross section and terminating at one end with a book 45. This core fits snugly withr in the tube and its sides define a series of gas channels 46 as shown in Figure 8. One of these channels is located along the bottom of the tube against which the flame im pinges. It is along the bottom of the tube that the heavier ceposits of carbon are formed in the usual type of burner which are diflicult to clean without taking them 'apart. The provision of a passage at this a point thru which the gas is free to flow prevents the accumulation of carbon deand gas the burner is preferably mounted upon a suitable base 4:? of fire brick or other plastic material. The base may be in one-piece or in sections as shown in Fig urea and completely covers grate bar 11 of the furnace with the exception of the central portion thru which the needle-valvev door 49 of the furnace and a supporting.

plate or shield 50 is fastened to the burner for supporting the same so that the plug can be conveniently unscrewed when door 4.9 is opened to clean the burner. This plate is suitably perforated as at 51 to receive the forward ends of tubes 18 and provides an air shield for the front of the burner.

This gas-generating device may be appliedin otherways than as here described and provides gas generating means of an eco monical character which is useful for both heating and lighting. The kerosene is supplied in liquid form from one container and isv stored, in gaseous form, in a dispensing container from which it may be returned to the heating burner or used for illuminating as above described. I

From the foregoing it is believed that the novel features of the invention, as well as the 'constructionand operation thereof, will be understood without further detailed description.

lVhat is claimed is:

1. A gae-generating device including a burner having generating tubes, plugs closing the opposite ends of the tubes and remo "able therefrom, and a removable core or filler for each tube, said core comprising a solid rod ofpolygonal cross section raving a catch-hook at one end and flat sides definingseparate gas passages along the inside or the tube. one of which is dis posed adjacent the flame-impinging side tube.

.2. A; gas-generating device including a burner having a flame tubeand generating tubes above the flame tube to be heated by the flame of the latter, a centrally perforated base for supporting the burner or a furnace grate, means for supplying oil to the generating tubes for conversion into gas by the flame, means for conducting the gas thru the flame pipes for consumption therein, means for conveying any surplus gas from the burner to a place of storage, and valve means for regulating the feed of the gas thru the flame tubes, said valve means projecting below the grate of the furnace.

3. A gas generating burner for use in a furnace, comprising a. centrally apertured base of plastic material adapted to overlie and completely cover the grate of the furnace with the exception of the central portion, a burner mounted on said base and supported by the latter on a level with the fire door of the furnace, a perforated plate engaging the loops of the burner providing an air shield for the burner, and a pair of independent pipe lines penetratin the ash pit of the furnace from the outsi e of the latter and connecting with the said burner through the said central opening in the said base, one of said pipe lines being an oil-supply line and connecting with the inlet end of the burner, and the other pipe line being an oil preserve line and connecting with the outlet end of the burner for collecting any surplus gas passing beyond the jets of the burner. y

In testimony whereof I afiix my signature.
