COMPANY, OF BAYONNE, NEW
OF LONDON, ENGLAND, ASSIGNOR TO THE BABCOCK & WILCOX JERSEY, A CORPORATION OF NEW JERSEY.
STEAM-GENERATOR.
Specification of Letters Patent.
Patented Aug. 1, 1916.
Application filed April 9, 1913. Serial No. 759,831.
a subject of the Emperor of Austria-Hum gal-y, residing at'London, England, have invented certain new and useful Improvements in Steam-Generators, of which the following is a specification.
My invention relates to a water tube boiler, one feature of which is the arrangement of the generating tubes at a steep angle and inclined upwardly from a mud drum toward the front wall of the setting, and the connection of said tubes, at their upper ends, to headers which in turn are connected to a steam and water drum.
Another feature of my invention relates to an economizer in which the outgoing gases travel in a contrary direction to the flow of the water through the economizer.
In the accompanying drawing, which is a central vertical section of a boiler illustrating one embodiment of my invention, the numeral 1 designates the front wall of the boiler setting; 1' the rear wall; 2 the furnace; and 3 a'bank of generating tubes inclined upwardly and forwardly at a steep angle from mud drum 4 toward the front wall 1. In lieu of using tubes having their lower ends bent, and a drum 4 made of plain cylindrical plates, I may use embossed tube sheets, of well-known form, permitting the use of straight tubes. The
upper ends of the tubes 3 areconnected,
through headers 5, with one side of a steam and water drum 6. These headers may be of any well-known type, stayed or otherwise stiffened, thus assuring the greatest flexibility of the whole of the boiler. A bank of tubes 7, serving as downcomers, connects the steam and water drum with mud drum 4. The downcomer tubes may be bent or straight, depending upon whether cylindrical or embossed shell plates are used for the water or mud drum or drums. In the space between the banks 3 and 7 is located a superheater 8.
A series. of vertical tubes 9 may be arranged in proximity to the front wall, the upper ends of these tubes being connected to the headers 5, and the lower ends to a collector 10 connected to the drum 4 by return tubes 11.
Supported upon the front row of tubes of bank 3, and extending from drum 4, is a baflie 12, and extending rearwardly therefrom is a provide an eflicient cross baflle 13. Between the bank 3 and the downcomers is a vertical wall or baffle 14extending downwardly from the steam and water drum 6. Back of the tubes 7 is a vertical wall 15 rising from the floor and extending-upward a suflicient height to properly direct the gases among said tubes and to the upper or hotter part of the econo I mizer, the latter comprising a bank of vertical tubes 16 in thespace between wall 15 and the rear wall 1 of the setting. The length of these tubes corresponds substantially to the height of the setting and they are expanded at their lower and upper ends into drums 17 and 18 respectively, The tubes 16 may be bent at their ends, as shown, to enter the drums radially, or they may be straight if the drums are formed with embossed tube sheets instead of being cylindrical. Connected to drum 17 is a water inlet pipe 19, and connected to drum 18 is a water outlet pipe 20 leading to the water space of drum 6. Suitable baflies and shelves may be placed in the economizer chamber to cause the gases to cross and recross the tubes. The gases from thefurnaee are directed upwardly by baflle 12 and then across the uptake ends of the tubes 3 by baffle 13, then and then upwardly 'amongthe downcomer tubes to the upper or hottest part of theeconomizer, and finally among the economizer tubes to outlet 21, as indicated by the arrows.
The water is fed into drum 17, the coldest part' of the economizer, and rising through tubes 16 is heated by the gases flowing around the tubes in a. contrary direction. From drum 18 the water is fed into the steam and water drum 6 and passes through the downcomer tubes 7 into drum 4 from which it passes through the tubes of bank 3, and tubes 11 and 9, to headers 5 .and drum 6. a
From the foregoing it will be seen that I form of boiler and an arrangement of an economizer therewith, by locating the economizer within the setting and in such manner that the gases will travel through the economizer chamber in a contrary direction through the tubes.
The advantage derived by using the economizer described is that there will be an automatic regulation to maintain approxito the flow of the water 7 I at mately an even temperature at each horizontal cross section thereof and a tendency to produce a laning action where the cold water will short circuit through some of the tubes will be eliminated. 0n heating the water it becomes of a lesser density and with an upward flow the water in the tubes which absorb the most heat circulates the most rapidly, with the result that more cold water is drawn into, the tubes having a rapid circulation than into those having a less rapid circulation, which tends to equalize the temperature of the water in the difi'erent tubes. By passing the gases downward over the tubes a highly etlicient action is obtained as the temperature of the tubes is uniformly decreased as the gases travel along the same, and the coldest gases on leaving the economizer come in contact with the coldest part of the tubes.
, What 1 claim and desire to secure by Letters Patent of the United States is:
1. A water tube boiler comprising a bank of tubes inclined upwardly toward the front of the setting, a mud drum into which the lower ends of said tubes are expanded, headers into which the upper ends of said tubes are expanded, a steam and water drum connected to said headers, a battle extending upwardly from the mud drum in front of some of said tubes, a bank of downcomer tubes connectingsaid drums, and a bafile extending downwardly from the steam and water drum between the first-mentioned tubes and the downcomer tubes.
2. A water tube boiler comprising a bank of tubes inclined upwardly toward the front of the setting, a drum into which the lower ends of said tubes are expanded, headers into which the upper ends of said tubes are expanded, a steam and water drum connected to said headers, a bank of downcomer tubes connecting said drums, a baffle wall extending downwardly from the steam and water drum between the two banks of tubes, and a battle wall extending upwardly at the rear of the downcomer tubes.
In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
