Description
April 19, 1932. LANGVAND 1,854,340
BAFFLE Filed Jan. 19, 1928 a if W INVEN TOR BY W (pied ATTORNEYS Patented Apr. 19, 1932 UNITED STATES PATENT OFFICE IVAR L. LANGVAND, OF BARBERTON, OHIO,- ASSIGNOR TO THE BAIBCOCK & WILCOX COMPANY, OF BAYONNE NEW JERSEY, A CORPORATION OF JERSEY IBAIEFLE Application filed January 19, 1928. Serial No. 247,794.
This invention relates to a baffle that is particularly useful in a steam and water drum of a water tube boiler, but is not restricted to this particular use. The invention will be understood from the description in connection with the accompanying drawings in which Fig. 1 is a longitudinal section through a steam and water drum partly broken away showing an illustrative embodiment of the invention; Fig. 2 is a section along the line 22 of Fig. 1 Fig. 3 is a section along the line 3-3 of Fig. 1; and Fig. 4 is a horizontal section on an enlarged scale partly broken away showing some of the details.
In the drawings reference character 1 indicates a steam and water drum into the side of which, above the normal water level therein, rows of tubes 2 for introducing a mixture of steam and water, enter. A row of tubes 8 is connected to the lower side of the water space of said drum and a feed Water pipe 4: extends into the water space of the drum. The feed water pipe 4 is supported by straps 5 that are in turn supported by cross bars 6 of L-shape in cross section. The ends of the bars 6 are attached to lugs 7 that are anchored to the inside walls of the steam and water drum 1.
A longitudinal support 8 rests upon the cross bars 6 and a horizontal plate 9 rests upon the upper edge of the support 8.
A row of vertically disposed bafiies 1O rests upon the plate 9, these baflles being made up of sets of members so shaped as to cause the steam to follow meandering paths as it passes across the bafiles, thereby causing the steam and water to be separated from each other while the water passes downwardly into the water space and the steam crosses the bafiies and enters in a comparatively dry state into the upper portion of the steam space of the steam and water drum. One set of members of the bafiies 10 is made up of a central vertically disposed plate 11 of considerable width that is installed transversely of the drum. A cross plate 12 extends across one edge of the central plate 11 and has diverging portions to make a V-shaped member near the plate with edges of the cross plate terminating in portions 13 that are parallel to each other and parallel to the central member 11. Another cross plate 14 is located along the other edge of the central plate 11 and has its. edges turned back toward the central plate 11 as shown at 15.
Each one of the members of the other set of members that make up the battles 10 is composed of a pair of'vertically disposed plates 17 that have offset portions substantially parallel to each other which are connected by a portion substantially perpendicular to the offset portions. The oifset portions 'haveth'eir edges bent or turned backas shown at 18, and 19, said members contacting along one portion, as shown at 20. The members of the respective sets of members that make up the'bafiies 10 alternate with each other and are so disposed that the steam will take a meandering path when crossing the same as'most clearly shown in Fig. 4. A mixture of steam and water enters the steam and water drum 1 through the tubes 2 and passes'along the outside surfaces 12 (Fig. 4) into the spaces between the parallelportions 13 of adjacent members, thence divides passing to the right and left and back between portions18 and 19 on each side, thence along the other surfaces of the portions 12, and thence through the spaces between the members 17 and '11, thence out wardly between the portions 18 and .15 on each side, thus following a path that suddenly changesdirection several times, during which time most or substantially all of the water is separated-from the steam. The lower ends of the baflies 11 extend below the normal water level in the drum 1, so that the steam cannot pass below the ends of the baiiles. The spaces between the ends of the row of baffles 10 and the inside of the drum toward the inlet tubes 2 are closed by plates 22, the lower edges of which extend below the normal water level in the drum. A top plate 23 extends from the inside of the drum along the upper edge of the plates 22 to the bafiie 10. This plate 23 is provided with an offset portion 24: that lies along the upper from the tubes 2. A horizontal plate 26 is located above the baflle strip 25 and an inclined bafide 27 is connected to the horizontal plate 26. A plate 28 provided with openings 5 at intervals therethrough extends from the inner edge of the plate 26 to the plate 23 so as to leave a space between said plate 28 and the offset portion 2A of the plate 23. Nipples 29 may be provided to extend from the 10 plate 24% into the steam outlets 80 at the upper side of the steam and water drum 1.
After the steam has passed through the meandering paths of the baflles 10, it rises and if any entrained water has not been sepa- 15 rated by passing through the meandering paths, the baffles 25 and 27 aid in further separating water, so that the steam passes into the space between the plates 24 and 28 and thence through the nipples 29 in a dry 20 State.
I claim:
1. A baflle comprising sets of members, one set having a central plate and cross plates at edges of said central plate, said cross plates having portions substantially parallel to said central plates.
2. A baffle comprising sets of members, one set having a central plate and cross plates at opposite edges of said central plate, the edges of said cross plates being bent with respect to their main body portions.
3. A baflle comprising sets of members, one set comprising plates in contact with each other, each plate having oliset portions substantially parallel to each other with their edges bent backward.
4. A baflle comprising sets of members, one set having a central plate and cross plates at the edges of said central plate, and the other 7 set comprising plates, each plate of the lastnamed set having offset portions substantially parallel. to each other.
5. A bafiie comprising sets of members, one set having a central plate and cross plates at the edges'of said central plate, andthe other set comprising plates portions of which extend between said. central plate and one of the cross plates.
