UNITED STATES PATENT QFFICEv CHARLES PHILIPPE ALTMANN, OF LYONS-VAISE, FRANCE.
WATER-TUBE BOILER.
SPECIFICATION forming part of Letters Patent No. 715,737, dated December 16, 1902.
Application filed December 10, 1901. Serial No. 85,377. (No model.) I
and relating to water-tube boilers.
In all kinds of water-tube boilers it is necessary for economy of fuel and to increase the durability of the tubes that the water, which is a better conductor of heat than steam,
should remain in contact with the walls of the tubes it passes through. For this purpose it is important to prevent the formation of globules of steam occupying the whole crosssection of the interior of the tubes, which formation would expose the tubes to burning. For this purpose a thin plate of steel or other suitable metal is arranged in the interior of each water-tube, said plate passing from the lower end or" the tube up to and slightly beyond the Water-level in order that the plane of the plate may be generally transverse to the direction of firing.
In order that my invention may be easily understood, I have annexed to the specificationas an example drawings showing the im provement which forms the object of the present applicationapplied to a boiler of the system patented to me, No. 676,485, applica tion dated August 21, 1900. However, the invention can also be applied to any kind of water-tube boiler-that is to say, to any sys-' tern of steam-generators in which the water penetrates in the tubes in order to be heated.
In the annexed drawings, Figure 1 is a vertical section of the boiler. Fig. 2 is a horizontal section thereof on line A B of Fig. 1. Fig. 3
is a section and elevation showing a tube with a plate therein, the plate being notched or cut away on its edges, this figure being on a larger scale than the previous figures.
a a are the water-tubes of the boiler, and b b the plates arranged in the interior of each tube. It is evidentthat the tubes thus shown have each their lower horizontal part and their vertical part,'which is directed toward the center of the boiler, much more productive of steam than those parts which are diametrically opposed to them and that if the plate dividing the tube into two almost equal parts has a space left between its edges and the interior wall of the tube the part of the tube remote from the flame will form a reserve of water in order to fill the empty spaces in proportion as bubbles are formed along the plate. It will be understood that the plate must necessarily have-its plane perpen dicularly or transversely arranged to the flame and that a space should beleft between its edges and the inner wall of the tube. should be further stated that the said plates may be perforated by small holes, and even replaced by wire-gauze of small mesh. The
eflect producedviz., the prevention of the formation of the steam-globules--is always the same.
It should be mentioned that the arrangement of the plates in the interior of the tubes gives a great uniformity to the water-level in all parts of the generator, however great the quantity of steam required.
