Application filed March 29, 1913, Serial No. 757,671. Renewed May 6, 1915. Serial No. 26,426.
To all whom it may concern:
Be it known that 1, PETER G. SCHMIDT, a citizen of the United States, residing at Olympia, in the county of Thurston and State of Washington, have invented a new and useful Gas-Producer, of which the following is a specification.
This invention relates to improvements in gas producers, and more especially to that type of producer known as rotary gas producers, the main object of the present invention being the provision of a means whereby rotary gas producers will generate and deliver from fuel having high volatile content, a much cleaner gas than is generally produced by this type of producer at the prescut state of the art, thereby increasing the thermal efficiency of the producer, making the cleaning of the gas much easier and also eliminating the necessity of disposing of large quantities of tar and other condensates from the gas.
The present invention in one form is applicable to the usual type of updraft rotary gas producer which has previously been provided with a centrally disposed depending gas collector, the present gas producer being designed to deliver a very much cleaner gas, causing less trouble from pipe and flue stoppage and consequently frequent shut-downs for cleaning; and this also economizes in the apparatus, power and water for gas washing purposes in addition to giving the producer a high thermal efiiciency.
A still further object of the present invention is the provision of means whereby the usual form of rotary gas producer has its field of operation and usefulness increased for especially the use of soft coals and for the purpose where the use of clean or washed gas is mandatory in contra-distinction to raw or smoke gas-application, to which application the existing modes of producers are practically limited when using fuel of considerable volatile content.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings-Figure 1 is a vertical central sectional view of a rotary gas producer equipped with the present invention. Fig. 2 is an enlarged detail sectional view of a mechanically tight lubricated sliding joint between the air distributer, when employed with a producer having a rotating charging floor.
Referring to the drawings, the numeral 1 designates the base or supporting structure which is provided with the ash reservoir 2- through which the ash is adapted to be removed from the present producer. An air conducting flue '3 is provided upon the base and communicates with the twyer or distributing chamber 5, the same being provided with the flattened conicaltop 6, which is dis posed in spaced relation to the upper edge of the chamber 5 so that air will be distributed to the circumferential space into the ash zone and the lower part of the fuel bed.
The section 7 is provided with the outstanding rim 8, which Carries the water sealed receptacle 9 and is supported upon the rollers 11 carried by the supporting posts 12 and 12. By this means, the section 7 is permitted to be rotated relatively to the base 1. 1 V
The upper section 17 is provided with the outwardly projecting flange and supporting rim 18, which is disposed to rest upon a plurality of rollers 19 supported upon the posts 12 and 12', and thus provide an upper support for the section 17.
The upper end of the section 17 is provided with the annular water chamber 20 which with the apron 21 of the water cooled 'top or charging floor22 provides a water seal between the two, so that as the top 22 is rigidly and stationarily supported through the inturned ends 23 and 23 of the supports 12 and 12, the section 17 may be properly rotated. The flange 18 is provided with gear teeth 24, which mesh with the gear 16, so that the upper section may be rotated.
The coal or fuel inlet 30 and hopper 30' Y are provided, while the gas outlet 35 from the collector 33 is also provided. The usual poker holes 31, which are held tight by duit 36 to the annular conduit 86, disposed above the top 22 of the producer, there being" led therefrom and extending vertically downwardly into the upper end of the magazine 17, a plurality of diamond-shaped in cross section air conducting pipes 37. These pipes may or may not be connected together by means of the hollow ring 38 whichretains the lower ends of the pipes 37 relative to each other, the same being water cooled, water being supplied to the ring38 through the pipe 39, the opposite pipe 39 'being the outlet pipe.
As shown in Fig. 2, the sliding two-membered air distributer 40 isprovided, the section a1 of which is stationary, while the section 12 is fast to the top 22, which in this instance is mounted for rotation through the gearing 43 and 44:, the top 22 being mounted rotatably above the stationary section 17 of the producer. The pipes 37 are connected, as shown and receive the air supplied to distribute the same, a-s in Fig. 1, they, however, being moved through the fuel body.
The voids below thering 38 and also below the outlets of'the pipes 3737 are provided in the fuel, so that the air is properly admitted into the body of the fuel and at a point above the lower or inlet end of the collector 33.
What is claimed is:
1. A gas producer, one portion of which is revoluble, means-for revolving said portion, said producer having a lower air inlet, a centrally depending gas collector, and means for supplying auxiliary air into the producer adjacent the periphery thereof be low the top surface of the fuel bodyand above the lower end of the gas collector, such means including a plurality of downwardly depending angular shaped conduits, the longitudinal length of each of which is in acircuinferential alinement with the wall of the producer to reduce the frictional resistance ofthe contacting fuel.
2. A gas producer, hai'ingalower airiinlet, a stationary top,- a revoluble section, means for revolving said-section, acentrally depending gas collector, and means for supplying auxiliary air into the producer adjacent the periphery thereof below the top surface of the fuel body and" above the lower end of the gas collector, such means including a plurality of downwardly de pending angular shaped conduits carried by the top and'projectin g into the fuel body, the longitudinal length of each conduit being in a'circumferential alinement with the wall of'the producer to reduce the resistance of the moving fuel body, due to the revolving of the section.
3. A gas producer, having a lower air in let, a centrally depending gas collector, means for supplying auxiliary air into the producer adj acenttheperiphery thereof below the'top surface of the fuel charge and abovethe lower end of thegas collector, said means includinga plurality of downwardly depending conduits projectedinto the fuel charge, andmeans disposedupon the lower end of said conduits foriholding the conduits relatively to each otherland for bracing them against flexing due to the engagement thereof'with the fuel.
4. A gas producer, having-a lower air inlet, a centrally depending gas collector, means for supplying auxiliary air into the producer adjacent the periphery thereof below the top surface of the fuel charge and above thelower end of the gas collector, said means includingia plurality of downwardly depending conduits projecting into the fuel charge, and an annular.- retainingring connected to the lower ends of said conduits and forming. a spacing, means for said lower ends.
5. A gas produceighaving a lower air inlet, a centrally depending Jga-s collector carried by the chargingfioorand projectingwithin theupper section, means: for supplyingauxiliary air: into the producer at a point adjacent the periphery thereof and above the lower end of the gas collector, said means including a plurality of downwardly de pending. angular shaped conduits, the longitudinal length of which is: in a'circumferential path withthe :movementofthe fuel during-the-rotation of the'upper section,-and a water.jacketed annular member connected to the lowerends of saiddepending'pipes for spacing. the 'sameandiproviding avoid in the fuel body at a'pointbelow the same.
In testimony that l claim-the foregoing as my own, .I' have hereto afiixedm'y signature in the :presence of; two witnesses.
