UNITED STATES RENE ooNsTANT DUoHEsNE, oF vILLENEUvElLA.LANDE,-IN GEANTENAY,
' EEANoE.
lM-PRovEMENT-IN STEAM-BOILERS.
Specification forming part of Letters Patent No. 192,685, dated VJuly 3, 1877 application tiled Mey v22, 1377.
To all w/Lomtt may concern Beit known that I, REN CONSTANT DU- CHESNE, of Villeneuve-la-Lande, in Ghantenay, in the Department ofLoire-Inferieure, France, have invented a new and useful Improvement in Steam-Boilers 3 and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification.
The principle upon which my new, system of steam-generator is based consists in the employment of an internal fire-chamber, so 1ocated and arranged that the dame of the fuel, while acting powerfully in heating the generator, may arrive in a smoke-box or distributing-chamber, into which are also conveyed the inflammable but not inflamed gases from one or more other fire-boxes, through 'tubes presenting a large heating-surface.
By this arrangement the products of combuston that arrive in the smoke-box or distributing-chamber are inflamed again by the llame coming directly from the interior firechamber, and all the products of the various fire-boxes then pass through tubes, presenting a large heating-surface before reaching the chimney, and yield the greatest possible quantity of caloric either to convert the water in the boiler into steam, or to superheat the steam already formed, or to both generate and superheat steam. l
Other modes of utilizing the heat evolved by the inflaming of inflammable gases, as described, may be employed to obtain similar or different results. It will be understood, however, that the object of my invention is to reinflame, by means of the flame of one or more furnaces or fire-chambers, the gases of one or more other furnaces or fire-chambers, a large portion of the caloric of which gases has already been used efficiently by passing them through numerous tubes within the boiler, presenting a large heating-surface, so that, by reiniiamin'g these gases, they can be utilized again simultaneously with those coming directly from a furnace orfurnaces, by conveying them to the chimney through tubes presenting a large heating-surface.
Although the arrangement of parts through which the advantages of my invention are realized may be varied, I will give, in illustra- `tion of my invention, an arrangement which I have found in practice to be one of the best.
Figure lis a longitudinal section of a boiler taken upon the line A B vof Fig. 2, and Fig. 2 is a transverse section taken at the line C D. The llame from the central furnacea enters directly. and freely into the smoke-box or distributing-chamber b. To the right and to the left of the central furnace are arranged the furnaces c c', Whose products of combustion are drawn into the smoke-box b, but only after they shall have passed through the two series of tubes d d d, d d d. llhe flame of the central furnace meeting with no obstructions during its passage into the smoke-box, Will arrive there in the condition of a flame, and thus reinlame or kindle the gases which, coming from the side furnaces and obliged to pass through their respective series of tubes, already' described, will arrive at the smokebox in the formof gaseous fuel. The united products of combustion `or ignited gases from all the'furnaces reach the chimney through tubes, one portion passing through the tubes e e e, and the other through the series of tubes fff, heating, in this manner, the water contained in the boiler, and also drying and superheatin g the steam already formed.
I will add, also, that by the construction shown, as well as in others readily suggested, boilers can be made in a very simple and strong manner, at the same time permitting the level of the water within to be at the proper height, and, as shown in the drawings, the three furnaces can be easily united, and the back of the smoke-box secured to the rear of the boiler. smoke box, which is rather fiat, can be strengthened, as shown, pieces of angle-iron.
The doors of the furnaces, the man and hand holes, Ste., are attached asin all other wellconstructed boilers.
Another arrangement that I would mention as an illustration of modifications without departure from my invention, consists in the chimney, instead of being 'located in front,
The upper part of the' by adding a few- 2 massa tol secure by Letters Patent, is-
1. The combination, in a steam generator or boiler, of one or more furnaces or firechambers with one or-more other furnaces or fire chambers, under the construction substantially as shown and described, so that the products of combustion of the one shall be ignited or reinflamed by the other.
2. In a steam generator or boiler, a central furnace or fire-box, the products of combustion of which pass through a single ue into the smokebox, in combinationv with lateral furnacesand reboxes, the productsof com- -bustionof `which pass throughnests of tubular uesinto the same fire-box,substantially as'shown and set forth.
3. The combination, With one or more furnaces carrying its or'- their products of combustion to the fire-box in a flamed condition,
--andvvone or-more furnaces conveyingv its-.or
their productsof combustion to' the fire-box "in a non-inflamed but iniammable condition,
of return-fines passing the ymingled and inflamed gases tothechimney through the steam or Water portion of the boiler, or through both, substantiallyas shown and set forth.
In testimony whereof I have signed my name to this' specification before two' subscribf ing witnesses.
