GAS-PRODUCER.

Specification of Letters Patent.

Application filed November 3. 1913. Serial No. 799,018. Renewed October 26, 1915. Serial No. 58,067.

1 '0 all 107mm it may concern Be it known that I, BRUNO IERSEN, a subject of the German Emperor, and resident of Dortmund. (lrermany, have invented certain new aml useful Improvements in or Relating to (his-Producers, of which'the following is a specification.

The present invention relates to automatically working gas producers as described in my Patent No. 987195. Mar. '21, 1911, and the object of the present improven'ient is to provide higher temperatures in the gas zone, which is necessary when treating highly bituminous fuel. as the gases of such fuel are not put free at as low a temperature as those of usual gas coal. Now for producing higher temperatures in said gas zone, the latter are. according to the present invention. located nearer the combustion zone or burner than in the arrangement described in my above cited patent, in order to become more fully exposed to the heat of said burner.

The improved arrangement is shown in the accompanying drawings. in which:

Figure l is a vertical section of the device. Fig. 2 is a horizontal section of same. Fig. 3 is the stirring lever for the incandescent coal layer below the burner.

The fuel from a hopper (not shown) is conducted to feed channels Z) I) along which the fuel is conveyed to the upper part of the producer chaniber (l.

c is a central air admission pipe surrounded by the casing p between which and said pipe 0 products of distillation pass from the top j of the producer chamber down to the conical nozzle rings 0 0 arranged at the lower end of air pipe 0.

Near the top j, forming the gas zone of the producer chamber (1 is provided an annular gas channel a into which the evolved gas flows through connecting ducts c radially arranged all around and between said channel (,1, and chamber (Z and leaves the producer through a common pipe Z. Immediately on top of said annular channel a is arranged the wrought iron bottom plate at of the gas zone j, so that the latter is directly heated by means of the flowing out gases. Furthermore a second or additional gas channel a is provided in the inner wall of the producer and the gases from the upper or gas zone of the producer or from the channel a enter said channel a through a plurality of radial ducts r and enter again the gas zone through other radial ducts In the present invention the gas zone is so near the burner or comlmstion zone that when the layer of fresh fuel above the in candescent layer of fuel of the combustion zone is thin, the gas zone or chamber of the producer is exposed to'a very high temperature. Owing to such arrangement the working of such producer is very simple.

The etliciency of the distilling process increasing with the temperature. the lower portion of the vertical outer wall is cut away, because, owing to the concentration of the heat in the middle or combustion zone of the producer, a formation of slag and a resulting blocking of the feeding device cannot occur. m

At or below the zone of combustion the producer is provided with a water body into which the hot cinder falls and is disintegrated. The disintegrated cinder then drops through the body of water below the combustion zone to an upwardly inclined cinder discharges.

The cinder or slag disintegrating means comprises an axially mounted rotary cone h mounted on the. shaft of a driving wheel at the lower end of the conical wall If of the producer. Owing to such arrangement the larger slags slide downward along the conical wall f to the disintegrating cone h and are disintegrated between said cone and a grate 2'.

The caking and slagging combustion layer should be continuously loosened and broken up for providing a passage to the entering air, as the efficiency of the working depends from the latter. \Vith this object in view the breaking cone 71, is provided with a stirring arm is having an upwardly curved projection a. which breaks the burning fuel layer by alternately raising same and letting it drop again. Stirring means are not new, but those known until now are arranged above the incandescent layer, so that they are soon out of use and their work is not satisfactory. The stirring bar arranged underneath the combustion zone of the fuel, within a water cooled space, produces an efficient loosening of the incai'idescent material, and lasts very long.

I claim 1. In a gas producer, the combination of a casing having a central combustion chamber, said chamber having an annular gas passage communicating at intervals with the an auxiliary passage which communicates at intervals with the combustion chamber, a plate overlying the two passages and forming with the top of the casing a ga receivmg chamber which communicates with the combustion chamber, a tubular casing eX- tending from the top of the easing into the combustion chamber, said tubular casing having openings to form communication with the gas receiving chamber for the admission of gas. a pipe in the tubular casing to supply air to the gas admitted to said tubular casing, and means for supplying the combustion chamber around the tubular casing with fuel.

2. In a gas producer, the combination of a casing having a combustion chamber and a gas receiving chamber above the latter, the casing having an auxiliary passage under the gas receiving chamber which communicates at intervals with the combustion chamber a tubular casing depending in the combustion chamber and formed with openings which communicate with the gas receiving chamber, a pipe extending into the gas tubular chamber to supply air to the combustion chamber, a plurality of spaced nozzles at the bottom of the pipe, the air passing through the pipe drawing gas through the spaces between the nozzles from the gas receiving chamber, a. partition in the tubular casing, said partition having an opening in line with the pipe.

3. In a gas producer, the combination of a casing formed with a combustion chamber surrounded by a gas passage which communicates with said combustion chamber, said casing having a gas receiving chamber formed between the top of the casing and the top of the gas passage, the casing having an auxiliary passage under the gas receiving chamber which communicates at intervals with the combustion chamber an exit pipe communicating with the gas passage, a burner depending into the combustion chamber and comprising a tubular shell having openings near the top which communicate with the gas receiving chamber, an air supply pipe depending into the tubular casing and having at its lower end a series of spaced nozzles through which the gas is drawn from the gas receiving chamber by the air in the pipe, and a partition in the tubular casing, said partition having an opening in alinement with the pipe.

4. In a gas producer, the combination of. a casing having a'central combustion chamher and a gas passage surrounding said combustion chamber, the walls of the casing having openings to form communication between the combustion chamber and the gas passage, an outlet pipe connected with the gas passage, the Walls forming the upper part of the combustion chamber being downwardly and outwardly inclined, said wall having an auxiliary gas passage which oommunicates at its bottom and top with the upper part of the combustion chamber. a plate covering the two gas passages and the space formed between the latter and the top of the casing forming a gas receiving chamber, a burner depending into the combustion chamber, said burner comprising a shell and an air inlet pipe, said shell communieating with the gas receiving chamber to supply gas to the air introduced through the pipe to the combustion chamber, and

means for supplying fuel to the combustion s chamber.

In testimony whereof I have hereunto set my hand in presence of two witnesses. BRUNO VERSEN. [1,. s.] Witnesses: I
