ALFREDl BERNEY, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO NATHIEL A. DUTTON, OF SAME IJLAGE.
HEATING AND CIRCULATING WATER IN BOILERS.
SPECIFICATION forming' part of Letters Patent No. 239,308, dated March 29, 1881.
Application filed September 22, 1880 (No model.)
To all whom it muy concern Be it known that I, ALFRED BERNEY, a eiti- Zen of the United States7 residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Heating and Oirculatin g Water in Boilers 5 and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as 1o will enable others skilled in the art to which it appertaius to make and use the same, reference being had to the accompanying drawi gs, and to letters or ligures of reference marked thereon, which form a part of this specification. `My invention relates to apparatus for heat- .fing and circulatingthe water in locomotiveboilers, and also in assisting the combustion of the fuel,respecially for burning anthracite zo coal, which, as is well known, has and can be done very imperfectly with the apparatus now in use', and the object is to create a better circulation of water in the boiler, and thereby `also increase the evaporative efliciency and 2 5 heating qualities, and at the same time to burn less fuel and entirely consume the sparks, cinders, and products of combustion, and prevent their escape into the air.
The invention consists, first, in placing a 3o number of tubes, forming hollow grate-bars, a short distance above the common grate-bars, and connecting them with the front and rear water-legs, so that the fine burning coal and cinders can fall upon the lower grate and as- 3 5 sist in heating the water circulating through the tubes.
It also consists inplacinga water-diaphragm at an angle in the furnace and connecting it at the top with the water-space above the 4o crown-sheet, and about midway of its width, or near its lower end, introducing one or more pipes extending into the water-space of the boiler, and into said pipes a jet of steam, water, or compressed air, to create a circulation of water through the diaphragm and boiler.
lt further consists in supplying fresh air through a hollow furnace-door, whose upper end projects into the furnace, and-is provided at its lower side with a number of pendent 5o tubes, through which air, being rst heated, is
admitted into the lire, all of which will be more fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal section of a loeo- 55 motive-boiler with 1n y improvements attached. Fig. 2 is a horizontal section on line m. Fig. Sis an enlarged cross-section of the furnacedoor.
In the drawings, A is the shell of the. boiler, 6o in which the furnace B, tubes C, smoke-arch D, and stack E are of ordinary construction.
In the furnace are arranged, a short distance above the ordinary grate-bars F, a series of tubes or hollow grate-bars, G, connecting with i the front and rear waterlegs of the boiler, so as to create a circulation of water through them. The small coal, cinders, &c., passing through the spaces ot' the hollow grate-bars, fall upon the lower grate-bars, of ordinary construction, and assist in heating the circulating water through the hollow grate-bars. Above these bars is secured the water-diaphragm H, in an inclined manner, and connected at its open ends with the water-legs to the sides of the boiler, and at its upper end by tubes h with the water-space above the crown-sheet. Into the diaphragm H project one or more pipes I, passing through the rear-tube sheet, and extending near to the front-tube sheet, 8o where they are preferably provided with funnel mouths. Near the mouths of these pipes a jet-pipe, t', for steam, water, or air is int-roduced, by which the Water is forced rearward and through the water-diaphragm H and tubes 85 h,`back again into the waterspace ofthe boiler, above the crown-sheet, thereby creating a constant, rapid, and continuous circulation of water. In the lower part of the water-diaphragm is inserted a blow-off pipe, k, provided 9o with the usual blow-off valve,\so as to clean out any sediment that may accumulate therein, whenever necessary.'
To aid in the combustion of the fuel and generation of steam, I provide a furnace-door, K, which consists of a hollow shell or front, a, having a branch, b, at its upper side, at right angles to the front part. To the branch b are secured a number of pendent open en'ded tubes, c, through which air is introduced into loo the fire. In the front of the door are arranged a number of perforations, cl, over which a sliding plate or damper, e, is adjustably attached,
and through Which the amount of air desired can be regulated. The air, in passing up through the front part, a, into the branch b and through the tubes c, becomes highlyheated before it reaches the fire, aud assists in the burning of the fuel, and prevents chilling` of the tire.
Instead of the perforations and sliding damper the front part may be solid and arranged outside of the boiler-shell, as shown in dotted lines, and air admitted through the bottom, Which is then open, and may be pro vided With a damper.
I have shown my heater and circulator in connection with my spark-arrester and returnflues to the furnace; but it may be used with any other or Without any, if desired.
If desired, the Water-diaphragm in the furnace may be dispensed with, and the tubes or pipes I be continued through the f'urnace, as shown in dotted lines, and pass into the front Water space or leg of the furnace, when the circulation of the Water will be created, as in the first instance, and become highly heated in passing through the furnace. rIhe circulation may also be reversed in its course by forcing the Water in the tubes I in the opposite direction. The circulating-tubes I can be perforated along their entire length, more or less, With small holes, to make more perfect circulation.
Ido not confine my invention-t'. c.. pipe I- to the particular place shown, but place it or branches from it into any other part of the boiler.
The circulating-tubes can be easily inserted in new or old boilers by drilling one or more holes in the Hue-sheets, then inserting a screwplugin said hole or holes after the tube has been expanded to iit the hole.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, ls-
l. In an apparatus for heating and circulating Water, the method of creating a circulation through the Water-diaphragm and boiler by one or more pipes extending into the diaphragm at one end and into the water-space at the other, and provided with one or more forcingjets, substantially as shown and herein described. t
2. In an apparatus for heating and circulating Water, the combination of the hollow grate or tubes with the ordinary grate, arranged as shown and described.
3. In an apparatus for heating and circulat ing Water, a water-diaphragm, H, arranged in the furnace and connected by tubes h to the Waterspace above the crown-sheet, and by tubes I, provided with a jet, substantially as specified.
4t. In an apparatus for heating and circulating water, constructedl substantially as described, the furnace-door K, consisting of a hollowshell having a right-angled branch, b, provided with pendent tubes o, as and for the purpose set forth.
5. In an apparatus for heating and circulating water, the method of creating an articial circulation from the Water-space near front end of the boiler, toward the rear end yof the same, by means of one or more tubes extending from front to rear, into which a jetof steam, water, or air is introduced, substantially as shown and specified.
In testimony whereof I- affix my signature in presence of two witnesses.
ALFRED BERNEY.
