IMPROVEMENT lN STEAM-BOILERS.
Specification forming part of Letters Patent No. 205,765, dated July 9, 1878; application led February 23, 1878.
To all rwhom it may concern:
Be itknown that I, J ULIUs GUsTAv SCHMIDT, a manufacturer, of Berlin, Kingdom of Prussia, German Empire, have invented Improve ments in Tubular Steam-Boilers and that the following, with reference to the accompanying drawings, is a full and clear specification of my invention.
The latter relates to that class of tubular steam-boilers in which the tubes forming se ries of zigzag tubes or pipes are united to each other and to the water and steam drum by elbows, and in which are used more than one series of these zigzag tubes; and the object of it is to partly utilize in the best manner the heat of the fuel by the counter-current of the fire and water, and partly to generate completely dry steam.
. In the accompanying drawing, Figure l represents a vertical longitudinal section ot' the boiler; Fig. 2, half a front view and half a vertical cross-section, and Fig. 3 a horizontal section.
The feed-water enters, by a check-valve, c, at K, into the feed-water heater H, flowing into the lower row of the zigzag tubes A A until all the water-tubes of the water-reservoir and the lowest row of the steam-tubes are lled with it. The steam-generator is composed of steamtubes B B, joined by elbows, so as to form two or more vertical series of zigzag tubes, which are connected at the bottom with the water-drum C, and at the top with the steamdrum D, from which the steam for driving purposes is taken oii'. rIhe re burning upon the grate E touches the lowest row of the steam-tubes filled with water, but passes directly through the lueW to the top of the water-reservoir, and, enveloping its tubes, from there downpinto the flue F and into the chimney. Besides the lower row lled with .water and exposed tothe direct action of the re, all
the other tubes of the steam-generator are illed with steam, and subjected only to the radiant heat of the burning fuel. From the grate to the chimney the productsv of combustion take a direction exactly opposite to that of the feed-water, coming at the beginning in contact with its hottest, and leaving it on the coldest, part. Therefore the heat of the fuel is used at greatest advantage.
The steam generated and contained in the steam-generator B B is not subjected to the direct act-ion of the flames; but the radiant heat of the burning fuel is sufficient to make it per'- fectl y dry.
For the regulation of the iow of the water from the water-reservoir to the steam-generator, the cock L, itted with a regulating-valve, is interposed between them. All the other ttings, valves, cocks, &c., ot' the boiler may be as usual, and also the details of the construction of the boiler itself.
What I want to secure by Letters Patent 1. The separate water-reservoir composed of water-tubes of a tubular boiler, in combination with the steam-generator, situate-d so high above the former that its lower row of tubes is filled with water, for the purpose speoiiied, and substantially as described.
2. The construction of the steam-generator of a tubular boiler in such a Way that its steamcontaining tubes are subjected only to the radiant heat of the burning fuel, while all the tubes containing water are subjected to the action of direct heat, and in a direction opposite to the current of the feed-water.
This specification signed by me this 14th day of January, 1878.
JULIUS GUSTAV SCHMIDT.
