WATER-J ACKET FURNACE.
Specification of Letters Patent Application filed August 5, 1912. Serial No. 713,412.
To 117/ who/)1 2'2 may com-era:
lie it known that l. .losi-zrn A. \Yxnm-am, Jr.. a citizen of the United States, residing at Scranton. inithe county at Lackawanna and State ot Pennsylvania, have invented certain new and uset'ul improvements in Water-Jacket Furnaces. otwhich the following is a specification.
The present invention relates to furnaces of the same general type as that forming the subject matter of the Letters Patent of David Boies and Joseph A. \Yaddell, J12, No. 1,045.6(38, issued November 26, 1912. Said Letters Patent disclose an inclined grate, a fuel magazine located above vthe high portion of the grate and a combustion chamber over the main body of the grate; the magazine and combustion chamber being constructed of hollow boiler sections, each comprising an inner wall formed with a recess, providing one side of the magazine, and an inwardly inclined and downwardly extending water leg; there being a suitably related opposite magazine wall, water legs being disposed atsuch an angle as to form a constricted fuel outlet from the magazine presented toward the high point of the grate; the boiler sections-being also formed with an outer furnace wall, the lower portion of which extends downwardly and inwardly to provide the outer wall of the combustion chamber and located to leave between it and the inwardly inclined depending water leg. a relatively large combustion chamber located over themain body of the grate. 1n the illustrative embodimentof the apparatus selected in Letters Patent. No. 1,045,668, the grate is of the double inclined type presenting two surfaces extending downward aml out-ward synunetrically on opposite sides of a longitiuliual crest or ridge, and both wallsof the magazine constitute inner portions of the water jacket and have outer furnace walls related thereto in position to provide duplicate combustion chambers. This arrangement is well adapted for furnaces above certain dimensions, but involves certain complications when embodied in furnaces of certain reduced capacities.
The object of the present invention is to provide a construction in which the advantages ofthe above defined construction may be realized, measurably at least, in a water jacket furnace of relatively small dimensions, and consists primarily in embodying all the grate surface ina single incline on one side of the crest, locating the magazine toone side of the furnace, with its discharge mouth above said crest, with the combustion chamber, and the circulating passages for the hot gases,.at the other side of the furnace; the wall related to-the. inner magazine wall, to complete the, magazine, being in this instance, one of the outer furnace walls which ex;e.uds downwardly from the mouth of the magazine to provide an abutment for the high portion of the fire-bed and, preferably, also extending downwardly a distance corresponding to the other wall of the fire-box and there provided with circulating connection with said other Wall and fire-box. involves the advantages of adapting the general principles in a furnace with a single inclined grate, but develops certain increase in the heating area, as will be hereinafter more fully described,
The accompanying drawing represents a transverse section of the improved water jacket. furnace, the section being taken in the plane passing between two sections of which the furnace is to be built up.
A represents the n1agaz-ine,-B the fire-bed, C the combustion chamber and G the grate. The mouth (1- of the magazine A is above the high portion of the grate G, and at such distance that the natural flow of the. fuel of proper size, will develop an inclined surface.
of the tire-bed B, substantiallyparallel t0 the surface of the grate so as to produce a fire-bed ot' ttniiorm depth and leave the coinbustion chamber of relatively large dimensions extending above the fire-bed on lines approximately perpendicular thereto, so that there will be plenty of room for the distilled gases to intermingle with air and burn.
The furnace is built up of sections 1, each constructed with a top arch 2 and an inter 100 mediate arch 3, providing two separated horizontal fiues 5 and 6 which will he in com-immication at their ends, as is common in furnaces of this type, the arches 2 and 3 of the sections being made to abut so as to 105 prevent communication between the tines 5 and 6 except at the end. Each section is fur ther provided with an arch 4, but the sides of these arches are not in abutment so that the products of combustion pass vertically be- "Q Patented May 27, 1913.

tween them. 'ihe arch 3 is connected with the arch 2 by the converging up-t-akes 7, While the high point in each arch 4t is connected with the arch 3 above it-by a single up-take 8, so that aside from increasing the heating surface, the water rises, as its temperature increases, from the high point of each arch to the arch above it. This also has the effect of drawing the preliminarily heated water from the lower portion 9 of the furnace wall 9, which provides the outer wall of the fire-box, and also from the rear furnace wall 10, 10 passing through the water bridge l0 which is of less width than the members 1O and 11 the flow being downward from the upper portion and upward from the lower portion of said rear wall. The aforesaid connections also draw the preliminarily heated water from the relatively cool inner wall 11 of the magazine A and from the depending water leg 11 of said magazine.
12 and 13 represent front and rear base channels which are connected at one end by a cross channel 14 (shown in dotted lines) and which receive the return pipe 15 of the 16 represents the upper circulating connection between the sections through which the hot water is supplied.
1. A boiler furnace comprising a single incline grate, a fuel magazine above the high portion of the grate and a combustion chamber extending upwardly and outwardly from the main body of the grate; said magazine and combustion chamber being constructed of hollow boiler sections, each comprising three upwardly extending walls, to wit, an outer wall extending vertically from the high point of the grate and forming one of the outer Walls of the furnace, an intermediate wall terminating at a point adj acentto said vertical outer wall but above the surface of the grate and forming with said vertical outer wall a magazine with a restricted opening discharging upon the high portion of the grate; and a second outer wall extending upwardly and outwardly from the lower portion of the grate and forming with said intermediate wall a combustion charnber approximately perpendicular to the inclined surface of the grate; there, being arch walls extending between the intermediate wall and the outwardly inclined outer wall; all of said walls being hollow to provide passages for a heat conveying medium.
2. A sectional boiler furnace comprising a single incline grate, a combustion chamber substantially perpendicularly above the inclined surface of the grate, and a magazine having a restricted discharge opening vertically above the high portion of the grate;
the boiler of said furnace being constructed of sections, each formed with an outer magazine wall extending vertically upward from the high point of the grate, an outer coinbustion chamber wall extending upwardly and outwardly from the lower point of the grate, and an intermediate wall dividing the upper part of the, combustion chamber from the magazine and extending upwardly from a point above the grate and adjacent to the outer magazine wall; the upper portion of each of said walls being deflected to provide a Vertical portion extending to the top of the furnace and there being hollow arch walls connecting the intermediate wall .with the outer combustion chamber wall, and up-take passages extending from high points of the arch walls to the walls above the same.
The foregoing specification signed at Scranton, la., this twenty-third day of July,
