ALEXANDER S. GOLJDIE, OF UDDINGSTON, SCOTLAND.
FURNACE FOR STEAM-BOILERS, 81.6.
Specification of Letters Patent.
Patented March 6, 1906.
To all w/wm it may concern:
Be it known that I, ALEXANDER SUMMER- VILLE GOLDIE, a subject of the King of Great Britain and Ireland, and a resident of Uddingston, county of Lanark, Scotland, have invented certain new and useful Improvements in Furnaces for Steam-Boilers and the Like, of which the following is a specification.
This invention has reference to improvements in and relating to the furnaces of steamboilers and the like, and essentially comprises the fitting of an air-heating chamber within the furnace above the fire-bar plates.
In the accompanying drawings, Figure 1 is a transverse section, and Fig. 2 a front end view, of the furnace part of a horizontal type of steam-boiler as constructed in accordance with my improvements. Fig. 3 is a detached transverse section of the air-heating chamber above center fire-bar plates slightly modified in construction from that shown in Fig. 1. Fig. 4 is a plan view corresponding to Fig. 1, and Fig. 5 is a central longitudinal sectional elevation corresponding to Fig. 1.
I fit within the furnace a series of longitudinal plates, the center one A, which is plain, being very much broader than the sets B C at each side of same, while the latter have short projecting fingers b 0, respectively, round and over which the air is led through the open spaces 1) c. A central air-heating chamber E is fitted at the lower part of furnace below the fire-bars A B C'and extends, preferably, the full length of furnace. On each side of chamber E are formed the ashpits D below the narrow bars B C: The doors E D are fitted on the outside for cleaning purposes. The air passes from the outside of the boiler by suitable regulating means,
such as a door E, fitted at front of chamber E, and a tray F with an open center part is fitted over the top of chamber E and extends the full length of furnace. The central fire-bar plate A has projections A, which bear over the edges of the tray, leaving an open space between the tray F and plate A for the passage of heated air to the side projections and open spaces b c, from whence the heated air passes to furnace, as indicated by the arrows. The side fire-bars B Care supported over the tray F by the bearer-plates G.
5 5 veys air from outside the boiler to the fuel on each side of this chamber by means of T- shaped or other suitable openings I. These air-openings I in the hooded air channel-way H H may be of any convenient number and distributed as best suited to the different furnaces. The air is admitted to the chamber H by a sliding door J or like regulator at the front end. A partition K or partitions may also be fitted within this channel-way H 6 5 for the greater part of its height to divide the same, so as to cause a better distribution of the air to each side of the furnace.
As shown in Fig. 3 and also in Fig. 5, the hooded part H is detachably spaced from the lower part and may be supported by flanged bearings L on the latter, leaving airspaces between for the exit of heated air to commingle with the products of combustion in furnace. 7 5
Suitable doors M are fitted at the front plate of boiler on each side of the hooded airchalmber H H for charging the furnace with fue I claim as my invention 1. In the furnaces of steam-boilers and the like, fuel-supporting plates and a hooded central air-chamber located above said plates, with exits for the outflow of heated air, and a dividing-partition in said chamber in combination with an air-admitting sliding door at the front end of said chamber.
2. In the furnaces of steam-boilers and the like, the combination of a solid central firebar plate, an air-heating chamber below said plate, a narrow bar on each side thereof, open spaces on each side of said narrow bars through which the heated air passes to the furnace from said chamber, and a hooded chamber above said central plate withexits 9 5 therein for the outflow of heated air.
3. In the furnaces of steam-boilers and the like, the combination of a solid central firebar plate, a chamber beneath said solid plate,
a bar on each side of said plate, open spaces on each side of said bars through which the heated air passes to the furnace from said chamber, a hooded chamber above said plate ed part supported by flanged bearings on the To with exits therein for outflow of heated air, lower part. and means to regulate the air admitted to In testimony whereof I have signed my said chamber. name to this specification in the presence of 4. In the furnaces of steam-boilers and the two subscribing witnesses. like, the combination of the fire-bar plates, a ALEX. S. GOLDIE. central air-heating chamber below said plates, Witnesses: and a hooded chamber above said plates, said JOHN SIME, hooded chamber having its detachable hood- R. O. THOMSON.
