BABGOCK Kzi WILOOX COMPANY, OF BAYONNE, NEW JEEsEY.A CORPORATION oENE'w JERSEY BAFFLE FOR STEAM ANDWATEB iDRUMS Application filed March 4, 1926, Serial No. 92,133, and in Great Britain April 24, 1925.
This invention relates to a baflfle by which steam can be more effectively separated from a mixture of steam and water that enters a steam and Water drum, thus enabling more nearly dry steam to be withdrawn from the drum. The invention will be understood from the description in connection with the accompanying drawings, in which an illustrative embodiment of the same is shown. In
a the drawings, Fig. 1 indicates a sectional view of a steam and water boiler drum, in which the baiiie is installed; Fig. 2 is a section along the line 22 of Fig. 1; Fig.3 is a section along the line 33 of Fig. 1 and Fig. 4 is a section through a boiler of the Stirling type, showing where the bafiie may be installed. In the drawings, reference character indicates one of the upper steam and water drums of a Stirling boiler, and 11 indicates the other :1 drum. The lower or mud drum is shown at 12, and the drums 10 and 11 are connected.
by a bank of water circulating tubes 13, and a row of steam tubes 14;, while the banks of tubes 15 and 16 connect the drums 10 and 11 to the drum 12, all in the well-known way in boilers of this type. The boiler is provided with the usual baffles by which the hot products of combustion are directed over the bank of tubes 16, the superheater 18 and the bank of tubes 15 to the outlet.
The superheater 18 is connected to the steam space of the steam and water drum 10, by means of the tube 17.
A. number of brackets 19 are attached to the inside of the drum 10, immediately below the row of tubes 14, in any convenient manner, as by spot welding, or by means of screws. A. longitudinal plate 20, which terminates a short distance from the ends of the drum 10, is attached to the brackets 19, so that the plate will be somewhat inclined from the vertical. This plate is connected to a similar plate, that is preferably made of two sections 21 and 21, by means of bolts 22, with sleeves 23 to keep the plates spaced apart and provide a slit therebetween. The plates 21 and 21 are attached by means of bolts 24.- and 25 t0 the ends of brackets 26, which are, in turn, attached to the inside of the drum 10 by means of the screws 27. The plate 21 extends into the steam space of the steam and water drum 10, and the plate 21 extends below the normal water level in the drum, these plates 21 and 21' contacting with each other to form a substantially tight but sliding joint, to pro- Vide for slight contractions and expansions.
The spaces at the ends of the plates between the plates and the drum 10 are closed by means of end plates 28 that are attached to the drum, and to the other plates by means of angle irons 29- and 30, the lower edge of the plates 21 and 28 terminating short of the lower side of the drum to provide an'exit space for water that enters through the tubes 13.
The operation is as follows: Steam is generated in the tubes in the usual manner, and the mixture of steam and water flows through the tubes 13 into the steam and water drum 10, the steam rising and the water flowing downwardly, as indicated by the arrows in Fig. 2. The steam that rises from the surface of the water carries with it entrained water which is thrown out by the sudden change in direction of the steam as it passes to and through the slot between the plates 20 and 21. The water that was not entrained with the steam, flows under the edge of the plate 21, thus maintaining the level of water in the drum.
While this invention has been described in connection with the steam and water drum of a Stirling boiler, it is to be understood that it is applicable'to other devices where it is desired to separate entrained water from steam.
I claim 1. In a boiler drum, a baflie comprising plates spaced apart and located at different elevations, one of said plates being entirely above the normal water level in said drum, said baffle extending longitudinally of the drum and from the wall of said drum above the normal water level therein to a distance below the water level, and terminating short of the end of said drum, the spaces between the ends of said bafiie and the side of the drum being closed.
2. In a boiler drum, a baflle disposed longitudinally of said drum and comprising plates spaced apart and located at different elevations, one of said plates being entirely above the normal Water level in said drum, said baflie extending longitudinally of the drum and from the Wall of said drum above the normal Water level therein to a distance be low the Water level, and terminating short of the end of said drum, the spaces between the ends of said baflle and the side of the drum being closed by plates substantially perpen dicular to said baflle and the Walls of said drum.
ERNEST E. NOBLE.
