A CORPORATION OF NEW YORK.
COMBINED STEAM-GENERATOR AND STEAM-SUPERHEATER.
SPECIFICATION forming p of Letters Patent N 772,315, dated. October 11, 1904..
Application filed April 18, 1903.
T0 aZZ whom it may concern:
Be it known that I, JOHN MILNE, a citizen of the United States of America, and a resident of the borough of Brooklyn, county of Kings, State of New Yorlghave invented certain new and useful Improvements in a Combined Steam-Generator and Steam-Superheater, of which the following is a specification.
This invention relates to steam-generating apparatus, and has for its object the production of a steam generator or boiler which has connected therewith a steam-superheater, the latter being subjected to the hot gases and products of combustion.
Figure 1 represents a partial vertical section of my invention as on the line 00 m of Fig. 3. Fig. 2 shows a plan view of a fragmentary portion of Fig. 1. Fig. 3 is a partial front view and. sections of Fig. 1 on the lines w, x and 00 The invention is represented to consist of the upper drum A, from which extend steamgenerating tubes B, the latter connecting with a lower drum C. Baffle-plates B extend upwardly from the lower drum, and baflie-plates B extend downwardly from the upper drum A. Tubes or pipes D extend from the lower drum O and are capped by a manifold or header E, which latter is independent of and not connected with the drum A, its interior being isolated therefrom. Hand-hole caps E are secured in the header E to allow the cleaning of the tubes D and their removal for the insertion of new tubes. The said tubes D, with the header E, constitute an economizer.
To secure a superheater, two independent manifolds or headers F F are connected with tubes or pipes F and an outlet is provided in the said top header at F. The upper header F has its interior isolated from the upper drum, and the lower header F is connected with the lower drum O by means of piping H, in which latter there is fitted the valve H, the said piping being used to flood the superheater.
Steam-outlet pipes are shown at I, having the safety-valves I and horizontal connecting Serial No. 153,151. (No model.)
The drums A and O, with their tubes B, the header E, with its tubes D, and the tubes F, with their headers F and F, are inclosed by the rear wall K, front wall G, side walls L, top covering M, and bottom N, forminga chamber for the'steam-generating apparatus.
The furnace is shown at O, with its grates P, furnace-door R, and ash-pit door R. The crown S of the furnace is connected with the wall S", that supports the header F and forms a portion of the front of the boiler. An iron frontT is represented with movable panels T.
Buck-staves U are located at the rear of the generator, and buck-staves U are attached at the sides.
V isan outlet for the connection with the chimney, and cleaning-doors V V are located in the side Walls of the boiler. A blowoif W is connected with the lower drum C.
When using my steam-generating apparatus, the gases and products of combustion on leaving the furnaceO pass around and about the portion of the steam-generating tubes B in front of the baffle-plate B and also pass around and about the tubes F of the steamsuperheater. They ascend to the drum A and then descend, circulating about the tubes between the baffle-plates B and B and from thence pass upwardly around and about the tubes B back of the baflie-plates B and also about the tubes D of the economizer, after which they enter the chimney through the opening V. superheated steam is obtained at the outlet F and should it be desired not to use the steam-superheater the valves J are closed and the valves 1 opened, when the steam can be taken from the outlet of. the T-I, and at the same time the valve h in the piping H is kept open to flood the superheater tubes or pipes F to protect them from the hot gases of combustion.
The construction is such that, if desirable, the entire superheater can be removed after the valves J are closed. When the steam-superheater is used,
the valves 1 are closed, and it is evident that, if desirable, steam can be supplied both from the T I and from the outlet F Having described my invention, 1 clainn 1. In a steam-superheater the combination of piping extending from a steam-supply, a branch pipe extending from said piping, a a valve in said branch pipe, a valve in the piping beyond its connection with the branch pipe, a header connected with the end of the piping, steam-superheating tubes extending from the header, piping for water connected to the header, a valve in the latter piping, and an independent header capping the steamsuperheating tubes.
2. In a steam-generating apparatus and steam-superheater, the combination of an upper and a lower drum, a chamber inclosing the said drums, tubes connecting the drums,
