WATER-TUBE STEAM GEN'ERATO R.
SPECIFICATION forming part of Letters Patent No. 736,743, dated August 18, 1903. Application filed December 1'7, 1902. derial No. 135,592. (No model.)
T0 all whom it may concern/.-
Be it known that I, HAROLD W. KOLLE, a subject of the King of Great Britain, residing at 30 Farringdon street, London, England, have invented certain new and useful Improvements in Water-Tube Steam-Generators, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to water-tube steamgenerators of the Babcock and Wilcox type, in which a transverse mud-drum is connected to and beneath the rear headers.
The present invention consists in dividing the mud-drum by suitable partitions into separate chambers and connecting one of said chambers with a separate water-circulating system between the steam and water drum and the front header connection and connecting the other chamber with the rear headers to serve as a mud-receptacle.
In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation, partly in section, of a generator embodying the invention; Fig. 2, an enlarged cross-section of mud-drum and connections; Fig. 3, a sectional elevation of a modification of the invention; Fig. 4;, an enlarged cross- .section of a part ofFig. 3, showing the muddrum with its chambers transposed and connections arranged accordingly; and Fig. 5, a modified way of inserting the lower row of tubes in the drum.
As shown by the drawings, the mainrows of inclined water-tubes A, located over the furnace B, are connected to end headers O, which are in turn connected to a main steam and water drum or reservoir D, as in the ordinary construction of Babcock and Wilcox steam-generators as designed for land purposes. A lower or supplementary row or rows of inclined water-tubes A is or are provided, their forward ends being connected to the front headers of the boiler, while their rear ends are expanded into or Otherwise connected to a mud-drum E, to which are connected downflow-tubes F, leading from the cross-box on the steam and water drum D.
The mud-drum E is divided by a partition E into two compartments, whereof in Figs. 1 and 2 the lower one e and in Figs. 3 and 4. the upper one 6 is connected to the rear headers by nipples c to form a receptacle for solid impurities passing down the rear headers, which are periodically blown ofi through a'blow-off pipe furnished with a cock G, while the other compartment, e, serves as a means of communication between the downflow pipes F and the bottom row or rows of water-tubes A. A separate water-supply of water is thus provided to the tubes A. from the steam and water drum, so that these tubes, which are most fully exposed to the fire-gases, instead of being supplied with water through the lower ends of the vertical headers receive a full and direct supply from the reservoir D.
Having thus fully described my invention, I claim- A sectional steam-generator of the type described provided with a manifold or drum E located at the bottom of the rear headers 0 provided with a partition E forming noncommunicating chambers e e therein, a row or group of supplementary water-tubes communicating with one of the chambers of said manifold ordruin E and the front headers O; a series of downfiow-pipes F communicating with one chamber and the steam and water drum D and the rear header 0 communicating with the other chamber of the manifold or drum E.
In testimony whereof I affix my signature in presence of two witnesses.
HAROLD W. KOLLE.
