Application le March 5, 1908.v Serial No. 419,301'.

To .all whom it mai/. concem:

l Be it known that I, J osEF MALY, a subject 'of the Austro-Hungarian Emperor, and residing at Lttichaustrasse '14, Dresden, A.,

Grermany,l have invented certain new and useful Improvements in Gas-Producers, of which the following is a specification.

The subject-matter of-the present invention is an improvement in gas-producers and particularly in those in which the-air is supplied above a rotating ash-plate which serves compartments, whereby it is possible to introduce at definite parts of the producer air and steamat varying pressures, or only air, or more steam than air, or more air than. steam.v

In order that the invention may beclearly understood reference is made to the accompanying drawings in which two dierent embodiments are represented by way of example and in which Figure l is a vertical section, and Fig. 2 a plan of one embodiment, whereas Fig. 3 is a vertical section, and Fig. 4 a plan of the second embodiment.

In the form represented in Figs. 1 and 2 there is built on the rotating or revoluble ash-plate a and eccentrically to the same a` cas-ing. b which in plan is preferably shaped round, rhomboidal or the like and which rotates with the ash-plate. This casing communicates directly with a chamber d under the same accessible from without through a door o. Air is blown into` this chamber through an opening or pipe e. A channel f forming. a water-lock with a ring g projecting downwards from the ash-plate prevents the emission of the air below the producer.

As is seen in the drawing the upper part of the casingb is shapedconically-corresponding to the plan of the casing and at b1, .b2 like a step-grate. At the one side below i z'the casing b is also shaped conically. The upper part of the cone built on the casing Z forms a-ehamber z' separated from the lower ally.

'pai-t of the casing by a partition h and this chamber z' is provided with a number of openings c on its periphery. To the chamber z' there leads a special stationary blastpipe l through which can be introducedblast of higher or other pressure than into `the chamber d or the lower part of the casing b.

`The point m of the cone likewise forms a special chamber separated from the chamber z' by a partition o and is provided with a special conduit Ao which is particularly used for introducing steam of a definite pressure, but which however under certain circumstances can also Abe connected with a special air-pipe." In the'form represented in Fig. l

of the drawing, the pipe p could serve for p introducing compressed air. In the form represented in Fig. l the chamber z' is thought of as admitting air miXed with steam, or for air of 'variable pressure, whereas the chamber m is exclusivelyv for admitting steam. From the above description it i's at once clear that air, or air and steam, or only vsteam or only air of definite variable pressure or regulatable tension can be introduced optionally at three places or into three different zones of the producer. In the case of many kinds of fuel which-lie-very closely or form a compact ash, blastvof high tension without any admixture of steam will be admitted. `In the second zone, or through the second chamber z' since purer fuel is situated over the same and a higher temperature 1sl Several effects ,can be obtained by introducing steam yat the .point of the conical grate. Firstly it can Abe prevented that the stream of the gases generated above the grate joins together in tie center and the gases are prevented from burning upwards centric- The steam drives the stream of gases apart and also compels the air or mixture of air and steam admitted further below to disi tribute to the sides also and to pass through the whole of the cross-section of the proi ribs'andl the point or cap of the grate or cone is arranged as the drawing shows, somewhatf eccentrically, and consequently it has a moving or boring action in the center of the layers ofthe fuel.. The formation of lumps of ashes can also be prevented, an eX- cessive rise of temperature in the center of the producer being prevented by the decomposition of the excess of steam,and the eX: cessof heat, which is conducive to the formation of lumps of slag, is utilized for forming hydrogen by decomposing the steam. It is at once clear that .in the case of such admission of steam and airvariable withinv the ash-plate are pressed'out under 'the wa- -ter-level when the ash-plate is rotated and rise to the scraper or deflector g. and falls over the edge of the plate through Lthe conduit or chute 7'.

The form represented in -Figs. 3 and 4 differs 'from that represented infFigs.' l and 2 substantially by the chambers z' and n being I ydivided in addition by vertical partitions into compartments a and n and and z", the walls of the compartments being perforated. The chamber compartments n and i have independent pipes, one of these pipes Y conducts to n and the other to 2".,

, steeper than at the other parts of the pe- The principal purpose of` this is to admit more steam at a definite place, namely at the part of the conical grate which descends riphery, in order to Abreak up the'lu'mps of slag more quickly and powerfully, and to utilize the heat stored up vin the same for decomposing the steam. ln the form represented in Fig. 3 the'right-hand side of theA producer would work for forming watergas, and the left" hand side for air-gas. When the grate is rotatedI these two parts are`gradually displaced of course. Also the arrangement of the ribs s represented in Figs. 3 and 4 is of great importance; these ribs on the conical face of the grate must' contribute much to the uniform working of glass and iron, the lower part of thegrate the generator or to the ashes and slags falling'vdown simultaneously. As is at once clear, these ribs stir and move the burning layer of fuel, and above all break up the slags. i

For fuels which form slacks as. hard as and also the inner wall of the producer opposite the grate is provided with ribs in or,-

der to grind the slacks to powder when the grate lrotates in the manner of a stonebreaker. Since a sandy mass is formed r which in many cases binds like cement in the water-bath, knife like looseners lare atvducer, with a grate having a rhomboidal chambers, pipes opening into the upper tached at two or more places on theproducer-wall which dips into. the water-bath, said looseners reaching to the bottom of the dish or plate. When the plate is rotated these knives cut the layer of cement, so that the passage for the slacks or ashes below the producer which would otherwise be dimin. ished is kept open. l v

What I claim as my invention and desire to secure by Letters Patent is l 1. The combination, in a gas-producer, of a revoluble ash-plate having a hole in the' same and forming the bottom of the "producer, with a grate having a round or rhomboidal or the like cross-section mounted over said hole eccentrically on said ash-plate, said grate having one Aor more partitions dividing `the same into aplurality of chambers, and pipes opening into said chambers and aording admission thereto of air alone and steam alone, or air and steam mixed.

' 2. The combination, in a gas-producer, o

a revoluble ash-plate having a hole in the same and 4forming the bottom' ofthe procross-section mounted over said hole eccentrically on said ash-plate, said grate having one or more horizontal partitions dividing the same into aplurality of superposed ,95 chambers and alfording admissionv of air and steam and a main blast pipe opening into the lowest chamber and operable independently of said air and steam pipe.

3. The combination, in a gas-producer, of a revoluble ash-plate having a hole in the same and forming the bottom ofthe producer, with a grate having a rhomboidal cross-section mounted over said hole eccentrically on Isaid ash-plate, an annular channel for water under saidA ash-plate, a rin attached to the latter projecting into. sai

channel, said grate having one or more partitions dividing the same into a plurality of ,superposed compartments, pipes o ening 1.10

into the upper compartments and a Ording admission of air and steam and a main blast pipe opening below said ash-plate into the lowest compartment.

y 4. The combination, in a gas-producer,` of

a revoluble 'ash-plate having a hole in `the same and forming the bottom of the producer, with a pyramidal grate mounted over said hole in said ash-plate, said grate having a plurality of horizontalv partitions .dividin the same into a plurality of superposed c ambers, a plurality of pipes opening intol the lower chambers, and a separate pipe opening into the uppermost chamber in the point of the grate, the point of the grate 12,5

being situated eccentrically to the axis of rotation of said ash-plate, saidpipes affording independent admission.- of air and steam to'. the top and ,bottom chambers. 1

5. The combination, in a gas-producer, of

a revoluble ash-plate having a hole in the same and forming the bottom of the producer, with a pyramidal grate mounted over said hole on said ash-plate, said grate having a plurality of horizontal partitions dividing the same into a plurality of superposed chambers, said grate having a perforated vertical partition dividing the upper chambers into compartments, a plurality of pipes opening into the lower Chambers, and a separate pipe opening into the uppermost chamber in the point of the grate, the point of the grate being situated ecoentrically to pipes aiording admission of air and steam tothe top chamber independently of the supply of air and steam to the'lower chambers and permitting more steam to be supplied to one side of the upper chambers in said grate than to the other side. In testimony whereof, I afIiX my signature in the presence of two Witnesses.
