Specification ofLetters Patent.
Patented Aug. 9, 1910.
Application filed October 12, 1909. Serial No. 522,236.
To all whom it may concern:
Be it known that I, WILLIAM F. BUCK, of Chicago, in the county of Cook and in the State of Illinois, have invented a certain new and useful Improvement in Superheaters, (Case C,) and do hereby declare that the following is a full, clear, and exact description thereof.
The object of my invention has been to provide a superheater for locomotive boilers, which shall be especially adapted for use with a Mallet locomotive boiler, which superheater shall be simple in construction, eiiicient in operation, and shall be easily accessible for the purpose of repairs; and to such ends my invention consists in the locomotive superheater hereinafter specified.
In the accompanying drawings Figure 1 is a longitudinal sectional view of a locomotive boiler embodying my invention; and Figs. 2 and 3 are respectively sectional views taken on the lines m-m and y-Jy of Fig. 1.
I shall illustrate my superheater by the bestform which is known to me, but the superheater is capable of embodiment in many di'erent forms, and the illustrated embodiment is only to be taken as typical and not exclusive.
III the illustrated embodiment, the boiler shell 1, of a Mallet compound locomotive, is provided with the usual boiler or steam-generating section, consisting of a portion of the shell 1, a nre-box, not shown, a forward flue sheet 2, and the usual iues 3. In the forward end of the boiler is a feed-water heater 4:, and the feed-water heater' is separated from the said flue sheet to form a chamber 5 in which the superheater is mounted. The superheater, as illustrated, consists 0f a single cylindrical shell 6 having end flue sheets 7 and 8 respectively, in which are mounted flues 9. The superheater is divided into two separate compartments by an intervening partition or iiue sheet 10. The flues pass through the partition or flue sheet 10, and may be made tight in said Hue sheet, either by being rolled or by being prossed therein. A pipe 11 conveys steam from the steam dome to the rear superheater compartment. This superheater compartment is, as shown-in Fig. 2, provided with batlie plates, which compel the steam to follow a sufficiently long course to properly superheat it, and after escaping from the baffle plates the steam passes by a pipe or pipes 12 to the high pressure cylinders, not
shown. From the high pressure cylinders the steam enters the forward superheater section by a pipe 13. This section is also provided with baille plates to prolong the course of the steam through the superheater. The steam leaves the forward superheater section by pipe 14 and passes to the low pressure cylinders. i
In the operation of the boiler which is illustrated, the of combustion escape from the flues 3 of the steam-generating section, and pass into a chamber l5 where they are advantageously mixed. The main portion of the said gases then passes 'through the lues 9 of the superheater, a portion also passing between the superheater and the boiler shell, and the gases thus arrive at the chamber 17, where they are further interiningled, and pass through the feed-water heater.
The steam from the steam dome enters the rear superheater section by the pipe 11, and after passing through the prescribed course in such section, passes out through the pipe 12 to the high pressure cylinders. AAfter having done its work in the high pressure cylinders, the steam returns to the front superheater section through the pipe 13. The steam then passes through the front superheater section by the prescribed course, illustrated in Fig. 3, and thence goes to the low pressure cylinders by the pipe 14.
It will be observed that my superheater, while provided with two sections so that it superheats the steam both for the low pressure cylinders and the high pressure cylinders, is exceedingly simple in construction, being almost as simple as if there were but one superheater chamber.
I claim:
In a superheater, the combination of connections for a substantially cylindrical shell, flue-sheets closing the ends thereof, flues connecting' said flue-sheets, and a partition dividing the steam space into two sections, said intermediate flue-sheet having a flange fitting the inner surface of said inner shell, and the joints between said inner fluesheet and said flues being made steam-tight.
In testimony that I claim the foregoing I have hereunto set my hand.
WILLIAM F. BUCK.
