GAS BURNER.
Application filed March 31, 1924. Serial No. 703,245.
To all whom it may concern:
Be it known that I, FRIEDRICH Rr'ison, a citizen of Danzig, residing at Leverkusen, in the State of Prussia, Germany, have in- I vented certain new and useful Improvements in Gas Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.
My invention relates to improvements in gas burners, and more particularly in gas burners of the type in which a combustible gas or a mixture of air and gas under pressure is discharged through a nozzle composed of circularly arranged individual nozzles or bores and into a mixing chamber, the air for supporting combustion being drawn in by thesuction of the jets of gas through a passage or passages communicating with the mixing chamber. In apparatus of this type such as are now in use a high vacuum is produced internally of the jets of gas, which vacuum is higher than the vacuum 35 around the jets and therefore causes a flow of the air into the space surrounded by thejets. I have found that the air which is thus drawn into the concentric jets of as or mixture is not thoroughly mixed with the said gas. The object of the improvements is to provide a burner in which the flow of air into the concentric jet of gas or mixture is avoided, and with this object in view I provide a body between the concentric nozzles or bores by means of which the dead space between the said nozzles and the jets discharge therefrom is filled out, said body being shaped so as to form with the wall of the mixing chamber an outwardly flaring concentric passage. 7
For the purpose of explaining the invention an example embodying the same has been illustrated in the accompanying draw in'g showing a sectional view of the burner. In the example shown in the drawing my improved burner consists of a casing 2 having an admission chamber 5 communicating at 6 with a supply of a gas or combustible mixture, anda mixing chamber 7 having air inlets 9 and closed by a toraminated plate or sieve 8. Between the chambers 5 and 7 there is a tubular member 1 closed at its discharge end by a transverse wall 12 formed circumferentially with bores 4 for the discharge of jets of gas or mixture into the mixing chamber. The mixing chamber 7 shows a bushing 11 having an outwardly flaring inner wall and being fixed in position by a screw 13. To the wall 12 an externally screw-threaded block 14: is secured by means of a screw 15, which block has a filling body 10 screwed thereto. As shown the said body is in the form of a slender cone extending axially through the mixing chamber and the outwardly flaring bushing 11. Between the bushing 11 and the conical body 10 an outwardly flaring passage or nozzle of annular cross-section is provided.
The compressed gas or gaseous mixture is discharged through the bores 4 in the form of concentric jets drawing air for supporting combustion through the inlets 9, which air is mixed with the gas or mixture within the outwardly flaring mixing chamber. By means of the filling body 10 the production of a vacuum within the concentric jets of :gas or mixture and a flow of air into the same is made impossible, and the outwardly flaring nozzle provided between the body 10 and the bushing 11 ensures an efiective suction and mixture of the gas and air or additional air, which resultis attained even in burners of large dimensions in which heretofore a complete mixture could not be attained.
While in describing the invention reference has been made to a particular example embodying the same- I wish it to be understood that I do not limit myself to the construction shown in the drawing, and that various. changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
I claim:
A gas burner comprising a tubular member having an inlet for a combustible fluid under pressure and also having a mixing chamber provided with a discharge and also with an inlet for air to support combustion; anozzle mounted in said member, arranged intermediate theinlet for the com: bustible fluid and the air inlet of the mixing chamber, said nozzle extending into the mixing chamber and forming the sole means discharged from said nozzle, said body of communication between said inlet for being conical and having its base attached I combustiblefluid and the said mixing cham-- to the dischargeend of said nozzle.- 1 10 her, said noz'ile being provided with indi- In 'testim ony' whereof JI hereunto l-aflix 5 vidual apertures opening into the mixing my signature.
