Patented OcLlO, 1933 1,929,891 2 WATER TUBE BOILER William ALJones, Westerleigh, N. Y., assignor to" Fuller Lehigh Company, Fullerton, Pa., a corporation of Delaware :Applieation February 25, eo. Serial No. 4.3 1.115. I llClaims. (craze-235) This-inventionrelates to a Water tube boiler having furnace wall tubes so connected to the boiler that the water will not be entirely drained from the boiler in case of rupture of a furnace wall tube, and, at the same time, water will be supplied to the furnace wall tubes even when the water level is below the upper drums of the boiler. The invention will be particularly described in connection'with a Stirling boiler, but it is to be un-, derstood that the invention is applicable to other types of water tube boilers.
The invention will be understood from the'description in connection with the accompanying drawings in which Fig. 1 is a vertical section through an illustrative embodiment of the invention and Fig. 2 is a front view of the boiler, partly in section.
In the drawings reference characters 1, 2 and 3 indicate the upper drums of a Stirling boiler which are connected by means'of banks of tubes, 4, 5 and 6, in the well-known way, to the lower, or mud drum 7. t
A downcomer pipe 8 leads from the water space of one of the upper drums at each end thereof. In the illustrative embodiment the downcomers are shown leading from the water space of the drum 1. A connection 9 extends from each downcomer 8 to the respective ends of a horizontal header 10 that may be spring supported, as shown at 11 and is located in front of the front wall of the boiler furnace. A row 12 of front furnace wall tubes leads from the header 10 to the drum 1.
A connection 13 extends from each downcomer 8 along the outside of the furnace of the boiler to the respective ends of the horizontal header 14 that is located below the drum '7 and to the rear of the furnace, and may be spring supported, as indicated at 15. A row 16 of tubes extends from the header 14 to the drum 1. This row of tubes extends along the rear wall of the furnace and thence parallel to the bank of tubes 4 and in front of the same.
Lower headers 17 are located at the sides of the furnace. Rows of side wall tubes 18 extend upwardly from the headers 17 to the drum 1.
A pipe 19 connects the Y-connection 20 in each downcorner 8to the mud drum '7.
The usual water level gauge 21, burners 22, baffles 23, outlet 24, ashpit 25, superheater 26 and other accessories are provided for the boiler.
The downcomer pipes 8 and connections 9 will continue to furnish water to the furnace wall tubes so long as the water level of theboiler does not reach a point below the Y-connections 20. When the water level'reaches a point below the upper end of the-pipes 8, water for the furnace Wall tubes will be supplied from the mud drum '7 through the connections 19 to the pipes 8 for the wall tubes, the Y-connections 20 acting as weirs to regulate the water supply to the water wall tubes. In case of rupture of a furnace wall tube, the level of the water in the boiler cannot reach a point below the Y-connections 20 so that the danger of burning out the boiler tubes is obviated, as all of the water will not be drained out of them.
I claim:

4. In a water tube boiler, a furnace having wall cooling tubes, headers to which the lower ends of said tubes are connected, a pipe connecting the upper portion of said boiler to said headers, and a pipe connecting the lower portion of said boiler to said first named pipe at a point below the upper water level and abovethe lowest water level of said boiler.
5. In a water tube boiler, a header at the rear of the furnace of said boiler, a connection from the upper part of said boiler to' said header, a row of tubes from said header to the upper part of said boiler, said tubes extending along the rear. l 10 wall of the furnace of said boiler, and a connection from the lower portion of said boiler to a point in said first named connection intermediate its ends.
6. In a water tube boiler of the Stirling type, a header at the rear of the furnace of said boiler, a connection from the upper part of said boiler to said header, 2. row of tubes from said header to the upper part of said boiler, said tubes extending along the rear wall of the furnace of said boiler and in front of the front bank of tubes of said boiler, and a connection from the lower portion of said boiler to a point in said first named connection intermediate its ends.
'7. In a water tube boiler, a header at the rear of the furnace of said boiler, a connection from the upper part of said boiler to said header, and a row of tubes from said header to the upper part of said boiler, furnace wall tubes of said boiler connected to said connection, and a connection from the lower portion of said boiler to a point located above the lower ends of the Stirling boiler tubes.
9. In a water tube boiler, a header at the rear of the furnace of said boiler, a connection from the upper part ,of said boiler to said header, a row of tubes from said header extending along a furnace wall of said boiler to the upper part of said boiler, and a connection from the lower part of said boiler to said first named connection connected thereto at a point intermediate the upper and lower parts of said boiler.
