GAS BURNER.

Application led 'flfarch 10, 1921. Serial No. 451,398.

To @ZZ 'whom t may concer-n:

Be it known that I, FREDERICK IFI. IVILL- oox a citizen of the United States, residing at hicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas Burners, of which the following. is a specification.

This invention relates to a new and improved gas burner, and more particularly to a burner especially adapted for use in connection with dirty producer gas, that is, gas carrying a large amount of line particles of foreign matter.

Considerable difliculty has been experienced in the utilization of hot dirty producer gas in gas burners, due to the deposit of the impurities carried by the gas in finely divided form. These impurities tend to clog the pipes and passages and interfere with the formation of a proper combustible mixture.

It is an object of the present invention to provide a gas burnerI adapted to utilize these gases carrying particles of foreign matter without danger of clogging or closing the passages.

It is a further object to provide a burner of this type in which a complete intermixture of the gas and air is provided. It is also an object to provide a burner in which ample facilities for cleaning are provided.

Other and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my invention in the accompanying drawings, in which- Figure l is a longitudinal section of the burner; and

Figure 2 is a section taken on line 2 2 of Figure 1.

The burner comprises the gas receiving member 3 having the reduced gas discharge port 4f. The gas inlet connection 5 is located at right angles to the axis of the member 3 and the outer end of the member is closed by a removable plate 6. The gas receiving member is formed with a tapered discharge portion provided adjacent its .opening 4; with a laterally extending flange 7 by means of which the member is bolted to the carbureting chamber 8.

The carbureting chamber 8, as best shown in Figure 2, is circular in form and is provided with the tangential air inlet 9. It is further provided with a removable cover plate l() at its lowest point and a similar plate ll at an upper point.- This chamber 8 is provided with a laterally extending tubular portion l2 which is adapted to be secured to the furnace wall i3 by means of the flange 14. The portion Al2 and the entrance to the furnace are lined with refractory material l5 which is given a reduced entrance portion 16 and a slightly flaring exhaust portion 17 forming together a venturi mixing throat. It is to be noted that the mouth 4l of the gas receiving member extends inwardly beyond the side of the chamber 8.

rIhis burner as shown is particularly adapted for use with both gas and air under approximately two inches of pressure. The gas is introduced through the intake 5 by any suitable connection and is given an accelerated velocity as it passes into the mixing or carbureting chamber by means of the slightly restricted gas nozzle 4l. The air enters the carbureting chamber tangentially through the intake 9 and by virtue of its pressure velocity swirls around in the chamber and is taken into the venturi throat 16 substantially equally at all points. This very thorough intermixing of the air and gas in the carbureting chamber and in the venturi throat gives a flame that attains the maximum possible temperature in the interior of the furnace in a very short time, followingwhich the temperature can be maintained with minimum amounts of gas.

This thorough premixing of the gas and air results in very great fuel economy and the regulation of the character of the flame is absolute andthe flame is subject to control within exceedingly close limits. Ample opportunity is permitted in the enlarged receiving portion of the member 3 for the deposit of impurities from the gas, and these particles may be readily removed through the cover plates 6. The centrifugal action of the air in the chamber 8 upon any particles carried therein tends to deposit them upon the outer walls of the chamber, where they can be readily removed through the cover plates l0 and 11.

I claim:

l. A gas burner adapted for the use of gas and air under pressure comprising an inlet member having a large portion adapted to receive the gas, and a gradually constricted nozzle, a closedcircular carburetting chamllO ber surrounding the orifice of said nozzle, av tangential air inlet port in said chamber, and a venturi mixing throat leading from Said chamber in line With the nozzle.

2. A gas burner adapted for the use of gas and air under pressure, comprising an inlet member having a large portion adapted to receive the gas, a gas inlet port entering said portionat an angle to its axis, a y.gradually constricted nozzle, a closed circular carburetting chamber Surrounding the c orifice of said nozzle, the nozzle projecting into the chamber, a tangential air inlet port in said chamber, and a Venturi mixingl throat leading from said chamber in line With the nozzle.

3. A gas burner adapted for the use of gas and air under pressure comprising an inlet member having a large portion adapted to receive the gas, a gas inlet port entering said portion at an angle to its axis, a gradually constricted nozzle, a closed circular carburetting chamber surrounding the orifice of said nozzle, the nozzle projecting into the chamber, a tangential air inlet port in said chamber, a venturi mixing throat leading' from said chamber in line With the nozzle, an axial clean-out opening in said inlet member and a circumferential cleanout Opening` in the carburetting` chamber.
