Specification of Letters Patent. Patented S t 19 191 Application filed April 9, 1915. serial to. 20,280.
TocZZ whom it may concern:
- Be it known that I, IVILLIAM CROMWELL GURNEI, of the city of Toronto, in the county of York and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Smoke- Consuming Boilers; and I hereby declare that the following is a full, clear, and exact description of the same.
In my application for Letters Patent of the United States, Serial #845,326, filed June th, 1914, I have shown and described a smoke consuming boiler comprising a set of assembled boiler sections inclosing a furnace comprising a fuel chamber provided with a hollow water grate consistingof two or more separated sets of grate. sections with an unoccupied space between them, whereby. the sections of each set can expand and con tract independently of each other as a result of the variations of temperature therein and a fire chamber located below the hollow water grate in which the combustion of the gas from the fuel chamber occurs.
My present invention relates to an improvement in the construction of the smoke consuming boiler forming the subject 1natter of-the above application, and this improvement consists of making the grate of tubular bars arranged in two or more alined sets of grate sections spaced lengthwise of the furnace so that the tubular bars of each grate section can expand and contractindependently of the tubular bars of the opposed grate section; one of the objects of the in vention being to facilitate the stoking of the furnace which is eifectedby forming, through the boiler casing, apertures in line with the intervals between the tubular bars so that when a poker is inserted through these apertures it will loosen the fuel supported upon the grate, for its descent through the intervals between the grate bars to the fire chamber below.
A further object of the invention is to so arrange the boiler sections in rear of the furnace that the burnt gas will be forced to take a staggered course to the smoke outlet,
" as hereinafter described and more particularly pointed out in the claim.
In the drawings :Figure 1, is a front elevation of the boiler, with the furnace doors removed; Fig. 2, is a transverse sec tion of the same on the line a-a, Fig. 4, with the rocking grate bars omitted; Fig. 3,
is a similar view to Fig. 2, on the line Z) Z1,
Fig. 4; and, Fig. 4:, is a longitudinal section on the liner-0, Fig. 1. L ke characters of reference refer to like parts throughout the Specification and draw- .lngs.
The boiler comprises avbase a having a doorway Z) into the ash pit c for draft and cleaning purposes; the base a, in rear of the ashpit, having a wall (Z separating it from qthe combustion chamber Mounted on the bases is the boiler front f which, as Shown in Figxd, forms one of the water sections of the boiler. Supported upon the base a, in rear of the front f, are arched water sections 9 which, together with the boiler front f and bridge wall Z, inclose the boiler fur- ,nace consisting of the fuel chamber h and the fire chamber 2'. Formed through the boiler front fis a doorway for the fuel chamber h and a doorway 70 for the fire chamber 2', and. at the bottom of the fire chamber 2' is a set of rocking grate bars m.
Connected with the water spaces 7 of the boiler front is a Set of laterally spaced tubular grate bars 0 forming one of the grate sectlons and connected with the water spaces Z of the bridge wall Z is a set of laterally .Spaced tubular grate bars 0 forming the other grate section; the tubes 0, of being opposed to and in line with each other with an unoccupied space 0 between them so that they can expand and contract independently of each other as a result of the .variations of temperature in the furnace,
thus avoiding any liability on the part of ,thew atergrate to strain the boiler sections; the lateral spaclng of the grate bars pro- ,viding intervals through which the contents ,of the fuel chamber may pass into the fire chamber. I V I 1 V Formed througi ,the bridge wall Z, below the water grate, are passages 19 leading from the fire chamber 2' into the combustion chamber 9.
In rear of the bridge wall are boiler sections 1", r, r", r and r supported upon the base a, in rear of the partition wall (Z. In the boiler section 1 is a hollow baffle wall 8 forming part of that boiler section, with a combustion chamber 9 between it and the bridge wall Z. The baflle wall 8 extends from the base a to nearly the top of the boiler section so that the products of combustion entering the combustion chamber q will be deflected upwardly to the passage at the top of the bafiie wall and then into the combustion chamber between the battle wall 5 of the boiler section 1 and the bathe wall 8 of the adjoining boiler section 1, the movement of the products of combustion from the combustion chamber g through the base being prevented by the partition wardly through the combustion chamber 9,
horizontally around the bottom of the baflie wall 8, upwardly through the combustion chamber 1, horizontally across the top of the battle wall 8, downwardly through the combustion chamber ([3, horizontally across the lower end of the bafiie wall 8 and then upwardly through the combustion chamber to the smoke outlet u, partition walls cl and (Z extending downwardly from the lower ends of the baffle walls 8 and s to the bottom of the base for the purposeof causing the products of combustion to take the above described course; the battle Wall 8" in the present construction forming the back of the boiler.
In each of the combustion chambers q, 1, and are doorways c which permit of the products of combustion being viewed as they pass from the fire chamber i to the smoke outlet in and also to permit of the combustion chambers being cleaned; the ashes and soot therein falling into the base which is provided with doorways o for the removal of the contents thereof.
The fuel, when introduced through the doorway j into the fuel chamber it, is supported upon the grate formed by the tubular bars 0, 0, and when ignited the gas passes downwardly through the intervals between the tubular bars and is burnt with- 1 in the fire chamber 2', the coked fuel within the fuel chamber it also descending through the intervals between the tubular bars into the fire chamber and resting upon the grate i smoke outlet,
bars m where a secondary combustion is maintained to effect the complete combustion of the burning fuel in the fire chamber and the gas descending from the coking fuel in the fuel chamber. In the event of the intervals between the grate bars becoming choked, the introduction of a poker through the apertures w will break up the mass, part of which, in the vicinity of the tubular bars descending through the intervals between them to the fire chamber 2' and finding a lodgment upon the grate bars m. The apertures w, as shown in Figs. 1 and 4: are located in line with the intervals between the tubular bars and slightly above the same which permits of the insertion of a poker and its unimpeded movement from the boiler front to the bridge wall Z thus materially facilitating the stoking of the boiler.
It has been ascertained from actual use of this boiler that soft coal, even when the fire is first started, gives olf no visible smoke, the combustion of the fuel being practically perfect; this being effected by the downward course of the gas from the fuel chamber through the fire chamber to the combustion chamber, and the staggered course through the combustion chambers to the smoke outlet.
at the top and bottom of the boiler sections for a staggered circulation of the products of combustion from the furnace to the and partitions extending downwardly from each alternate bafiie to the bottom of the base, the boiler sections having covered openings into the combustion chambers and the base having covered openrings into each compartment formed by the partitions.
