FEED-WATER APPARATUS FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 226,006, dated March 30, 1880.
Application filed September 24, 1879.
To all whom it may concern:
Be it known that I, JAMES OURTICE STEAD, of Brooklyn, Kings county, in the State of New York, have invented certain new and useful Improvements in Feed-Water Apparatus for Steam-Boilers; and I do hereby declare that the following is a correct description thereof.
This invention is an improvement in the same line as several previous inventions of mine for which I have obtained Letters Patent of the United States during the last few years.
My invention relates to a new and improved construction and combination of certain parts, hereinafter shown and described, whereby an eflicient attachment for steam-boilers is obtained for distributing the feed-water through a system consisting of a hollow bridge-wall, pipes, and connections before entering the boiler, and causing the water to enter the up-' per surface of the inside of the boiler through a pipe perforated in top and bottom lines and running the entire length of the boiler. The perforations on the top of this horizontal pipe are for the purpose of distributing the steam equally throughout the boiler above the waterline, and the lower line of perforations for a similar distribution of the water to the waterline and over the entire upper surface of the tubes, so as to prevent the tubes becoming overheated in case of low water in the boiler, or in case feeding is started with low water in the boiler. The rapid circulation from the bottom of the boiler to the top causes the water to pass over and through those perforations in a fine spray over the tubes, which effectively prevents any accidents to the boiler caused by low water. There are also three equidistant water-connections on the bottom of the boiler, so as to supply the attachment with water when not feeding, and also to give it a more uniform circulation, thereby preventing the formation of scale.
In the drawings, Figure 1 is a longitudinal vertical section through the boiler and its oasing and across the hollow bridge-wall. Fig. 2 is a vertical cross-section through the boiler, and shows a longitudinal vertical section of l the boiler with the bridge-wall.
hollow bridge-wall. Fig. 3 is a similar section at the rear end, showing end of boiler and po' sition of pipes and bridge-wall. Fig. 4 is a horizontal section on level of center of hollow bridge-wall. Fig. 5 is a frontend cross-section of the casing, showing front end of boiler, bridge-wall, grate-bars, 850.
Similar letters of reference indicate corresponding parts in all the figures.
A represents a drum or hollow bridge-wall for distributingheated feed-water through the system of pipes, and is connected with each end and the center of the boiler, and distributes the water from three parts of the boiler equally. This bridge-wall is inclined and rests at the rear of the grate-bars X, as shown.
B is a feed-pipe for feeding into the bridgewall or drum A. G is a blow-off cock for blow ing the mud and sediment from thelower end of the drum or bridge-wall.
D is the pipe which connects the bottom of This pipe has a branch inside of the boiler to the front end, so as to take the water from the center and front end.
E shows a pipe running horizontally from bridge-wall to the back end of the boiler.
F is a coil of pipe lying under the boiler in the rear of the bridgewall and inclined to correspond with the bridge-wall. This coil takes the water out of the low side of the drum into the low side of the coil, while the high side of the coil and its last pipe go back to the back connection, and there form a continuous coil, F, at the end of the boiler and up into the steam-space.
G is a coil of pipes on the side walls of the furnace, leaving the front of the bridge and all near the end lying parallel with the boiler, returning back and forth, and inclined in opposite directions upward, and entering front end of the boiler. H is a similar coil between the boiler and the casing, and enters the top of the boiler. These side coils prevent the brick-work from burning out and the formation of clinkers upon it, and cause a rapid circulation in the boiler over the furnace.
Irepresents a pipe connecting with the higher end of drum on top, running alongside of the boiler, and turns up into front connection and connects with coil G from the side wall, and both enter one pipe on the end of the boiler.
While I have described one side coil coming out of the front of the bridge-wall, I can use one on the opposite side or between a battery of boilers. I can also take it out of the front end of the boiler and use it as a side coil on each side of the furnace. Either way may be used as is best adapted to the furnace in question.
J is a perforated pipe running inside of boiler close to top, and connecting with coils F at the rear end of the boiler above the water-line, while the front end connects with the perforated pipe in the center of the boiler on top.
K is a perforated pipe running parallel with and inside of the bridge-wall, distributing the feed equally throughout the drum through its various short branches and openings.
L is an air-pipe, perforated and just back of the drum, and has one or both ends open to admit air, and is so placed that the heated air coming through the perforations mingles with the flame and gases which pass over the bridgewall from the furnace, and insures more perfect combustion.
H are tubular bearing-bars for supporting coil F. Thelower end of each bar H is connected under the water-line of the boiler, while its higher end is connected above the waterline, thus insuring a circulation of water through bars M, preventing their burning out.
I may employ a side coil, which takes'the water out of the front end of the boiler near the bottom, and returns along on the side wall of the furnace back and forth, inclined upward, and returns back into steam-space in front of the boiler. Vhen this side coil is used I may dispense with the drum-connection; or I may employ a side coil which comes out of the front side of drum, and runs along the side walls of the furnace back and forth, and turns over into top of boiler into the steam-space.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination of a feed-pipe, a hollow bridge-wall or drum, a feed-distributing pipe therein, one or more series of heating-coils, and a distributingpipe extending the length of the boiler and perforated on top and bottom lines, substantially as and for the purpose described.
2. A perforated distributing-pipe extending the length of the boiler, in combination with feed-waterh eatin g-coils connected at and entering into each end of the boiler, substantially as and for the purpose described.
3. A horizontal heating-coil arranged beneath the boiler and in rear of the bridgewall, and a connected vertical coil arranged at the end of the boiler, in combination with a drum or hollow bridge-wall and a perforated distributing-pipe, substantially as and for the purpose described.-
4. A heating-drum or hollow bridge-wall, its contained distributing-pipe, and a pipe connecting said drum with the bottom of the water-space of the boiler, in combination with a coil or coils arranged at the side or sides of the furnace, and connected with theboiler, substantially as and for the purpose described.
5. A coil of water-heating pipes arranged horizontally in the rear of the furnace beneath the boiler, in combination with a feed-heating drum and a series of tubular supporting-bars extending from beneath said pipes to above the water-level of the boiler, substantially as and for the purpose described.
