HENRI BEDET, OF LA PLAINE ST. DENIS, FRANCE.
STEAM-G EN ERATOR.
SI-ECIFICATION forming part of Letters Patent No. 694,236, dated. February 25, 1902.
Application filed November 5,1901; Serial No. 81,272. (No model.)
To (0M whom it may concern:
Be it known that I, HENRI BI'JDET, engineer, a citizen of the French Republic, residing at La Plaine St. Denis, Seine, France, (having post-office address 15 Rue de la Justice, in said city,) have invented certain new and useful Improvements in Steam-Generators, of which.
the following is a specification.
This invention has for its object to provide a steam-generator by which steam can be instantaneously generated, the said generator being constituted by closed tubular elements containing a bath of molten tin or other metal or alloy having a melting-point which will enable it to be maintained in a liquid or molten condition by the application of heat. A thin tube of U form dips into the metallic bath, the lower bend being perforated. The upper part of the return branch of the said U-tube is bent downward, and the outlet at this end is above the metallic bath and is presented toward it. This new generator produces steam very rapidly and abundantly without metal or alloy from the bath being carried out with the steam.
In order that myinvention may be readily understood, I will describe it more particularly with reference to the accompanying drawings, which represent in vertical section one element of a steam-generator made in accordance with my invention.
Figure l is a central vertical section. Figs. 2 and 3 are sectional plan views showing modifications of the form or configuration of the tube a. Fig. 4 is a partial vertical section showing a modification of the arrangement for bringing the water and alloy into contact.
a is a closed tube containing a bath b of liquid tin or other suitable metal or alloy. Into this bath dips a long U-shaped tube, the lower part c of which is perforated at d. Vater to be evaporated enters through the elbow-piece 6 into the downward branch f of the U-tube, the outlet of which is at the other end at top of the return or upward branch g, which is of such a length that the outlet is above the molten metallic bath, the said end being bent downward so as to form a third branch g, which presents the outlet h toward the molten metallic bath. Above the bath is a steam-space t, which is in communication with the steam valve or cook by a connecting-piece j, containing baffles to arrest any small particles of molten metal or alloy or water which might be carried up by the steam. A plug m allows the said connecting-piecej to be readily examined and cleaned. In practice, however, no such metal oralloyisfoundinthisconnecting-piece. The water does not pass into the bath through the perforations d in the lower bend of the U-tube, as if it did it would evaporate with violence on comingin contact with the molten metal or alloy and by bubbling therethrough would carry metal or alloy into the said connecting-piece. The water on reaching the lower part of the U-tube goes up the upward branch g and carriesup with it molten metal or alloy from the bath in the mannerin which steam in a Gitfard injector carries with it feedwater. The entrained metal or alloy by intimate contact with which the water is vaporized is thrown back into the bath through the outlet at the end of the branch g.
A steam-generator constructed in accordance with my invention may contain any number of elements such as I have described, and any suitable means of heating (by the combustion of hydrocarbons, for instance) may be employed which will keep the bath in the requisite liquid or molten condition. A bed of pulverulent carbon 1) may cover the metallic bath in order to save the same from oxidation.
The simultaneous circulation of water and molten metal in the tubular system may be as indicated in the Fig. t. The feed-water of the pumps can rush from the tube 0 in a separate tube 9. The metal of the bath will then come up with the water in the tube 9 through the annular space 61.
I have described what I consider the best way of constructing the elements according to my invention; but I do not limit myself to the precise details described and illustrated.
Having now particularly described and ascertained the nature of my invention and the manner in which the same is to be performed, I declare that what I claim is 1. In a steam-generator, an outer tube adapted to contain a molten alloy, a U-shaped inner tube suspended in said outer tube and provided with perforations in its lower portion, the discharge end of the inner tube being above the surface of the alloy and bent 7 to present the orifice toward the latter, substantially as described.
2. In a steam-generator, an outer tube adapted to contain a molten allo; and an inner water-tube connected with a source of supplysubmerged in said alloy and so constructed as to admit the latter to its lower submerged portion, the discharge end of said inner tube being bent to bring the orifice above and presented toward the alloy, substantially as described.
3. In steam-generators of the class described, a tube to contain a molten alloy,
