EUGENE RAGOT, OF BETTAINGOURT, AND PAUL PIERRE-HERVOTTE, 0F JOINVILLE, HAUTE-MARNE, FRANCE.
GAS-PRODUCER.
Specification of Letters Patent.
Patented Jan. 6, 1914:.
To all whom it may concern:
Be it known that we, EUGENE RAGOT and PAUL PIERRE-HERVOTTE, citizens of France, residing, respectively, at Rue de la Gare, Bettaincourt, and 10 Rue des Royaux, Joinville, Haute-Marne, in the Republic of France, have invented new and useful Improvements in Gas-Producers, of which the following is a specification.
This invention relates to gas producers containing two superposed combustion zones and has for object an improved producer consuming fuels of the most diverse nature either alone or mixed, such as saw-dust, wood waste, charcoal dust and other fuel waste.
The invention consists in the arrange ment that the lowermost of the two superposed combustion zones, where the most in tense combustion takes place is arranged immediately above a water cistern, so that the ases produced are compelled to pass immediately through the water before reaching the exhaust flue. Thechief advantage of this arrangement is that it permits of utilizing fuels of a nature rendering them quite useless in ordinary producers, this being due to the fact that the escaping gases are immediately washed as soon as they leave the interior of the producer, the ashes and other solid articles carried away with said gases being lmmediately arrested in the water, so that the exhaust channels into which the gas is directed are not liable to be obstructed by the solid particles, which would invariably take place in gas producers already known, in view of the considerable amount of solid particles carried away with the gas when low grade fuels such as above cited are used.
One example of the improved gas producer is illustrated in the accompanying drawings in which, Figure 1 is an elevation, Fig. 2 is a horizontal section of the grate, Fig. 3 is a detail in vertical section of the cistern, Fig. 4 is a vertical section of the whole producer at the line 4-4 of Fig. 5. Fig. 5 is a horizontal section at the line 5-5 of Fig. 4.
The walls 1 of the producer are of fireproof material and are surrounded by a metal envelop 2. The producer is mounted on a water cistern 3 and supports at the top another water cistern or tank 4 for supplyng the water injected along with the blast into the producer when utilizing certain fuels. The producer also supports a charging platform 5 of the usual construction.
The inside of the gas producer has the form shown in the drawing that is of four superposed conical sections united at their base, the small upper base forming the charglng opening being normally closed by a cover 6. At the small lower base is fitted a perforated cylindrical member 7 supporting the grate bars 8. This grate is in three pieces (Fig. 2) the center part being capable of sliding to permit of cleaning. This formation of the inside of the producer gives rise to two combustion zones at 9 and 10 and provides a double inverted combustion when the lower combustion zone 10 is the seat of the more intense heating. The upper zone is fed with air by four supply openings 11 arranged 90 apart one of which 11 is of larger diameter than the others and gives access to the interior of the producer. The lower zone is fed with air by four other similar openings 12 displaced by 45 with respect to the upper openings. The opening 12 is of larger size than the others and is closed by a door 17 which facilitates the breaking up of the fuel when necessary in the lower zone of the producer. A removable fire proof block 18 is provided which may be taken out to facilitate access to the lower zone.
All the openings 11 and 12 are connected by vertical pipes 13 with a common annular receiver 14 arranged near the top of the producer and obtaining its supply at 15 in any suitable manner. Valves 16 enable the air injected into the different parts of the producer to be regulated at will.
The lower zone 10 of the producer is located immediately above the water filling the cistern 8, which would rise above the grate bars 8 were it not prevented from doing so by the pressure of the air. This system at one part of its periphery is provided with an outlet tank 3 (Figs. 3 and 5) comprising a pipe connection 19 for the outlet of the gas which proceeds first to a washing device and then to a purifier. A vertical partition 20 projects into the water and normally prevents the gas from flowing out through the open duct 21 at the top of the tank. The object of this ductgis' to enable the gas to escape in case of an accumulation .of gas caused by a stoppage or other reason,
oils,.tars, and the like entrained-by the gases 15:
-- Owing to this double inverted combustion are finally volatilized and compl'etelyburned.
theigasesarriving at thewater cistern 3 are [thus comparatively pure and all materials capable of caking and obstructing the grate bars and other-parts of the grate, are burnt.
Should however caking occur and a breaking up-ofthe-fuel be necessary, this can be very easily effected without a prolonged stoppage ofthe operation of the producer. 25
- the air injection, toremove theblock 18' and It is only necessary after-=having-stopped introduce through the door 17 of the passage 12? iron rods adapted to support the-"charge of 'fuel inside the producer. Theono'ving part of the grate bars '8 is then'drawnout =-so as to allow-the fuel in the lower zone to fall into the cistern 3'whereupon thewa ll of said zone is easily cleaned. The producer; is started again without difiiculty.
The=gas on issuing from the lower zone 10 passes through the perforations of the plate 7,-and the grate bars and comes in contact with the water in the cistern' 3and bubbles "through this water becoming-washe'dand 40' cooled in the process. It escapesas has been described-into the lateral tank-3 and the pipe 19. The ashes'and/fine solid parti'cles :carriedaway with the :gases are "thusretained in the water and prevented from clogging intothe exhaust pipes. Pipes *'not shown enable the air injected to be mixed with a suitablequantity of water from the upper tank.
We claim:
1.. In a gas producer, .in-combination: a producer Tshaft having a restricted cross section at the bottom and at a point intermediate its height, means for closing said producer shaft at the top, means for admitting air, into. said producer shaft atpoints. immediately above b the restricted portions thereof, and 'thusforming in the producer two superposed combustion zones, a water cistern located immediately beneath the lower combustion zone so that the gases leaving Ithe "producerare "compelled to first pass through the waten and anexhaust pipe for the gas connected to said water cistern at i the outside of: the :lower opening of the producer shaft, "*substantiallyas described 2 and for the purpose set forth. I
2. In a gas produceryincombination: a
