STEAM-BOILER FURNACE.
SPECIFICATION forming part of Letters Patent No. 595,666, dated December 14, 1897. Application filed July 17, 1897. Serial No. 644,889. (No model.)
To all whom it may concern: I
Be it known that we, DAVID YOUNG and -WILLIAM I). LEWIS, citizens of the United States, and residents of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Steam-Boilers, of which the following is a specification.
This invention relates to boilers for generating steam; and it consists in the new and peculiar constructions and combinations of elements whereby a perfect combustion of fuel and complete consumption of the products of combustion are obtained by the methods and means substantially as hereinafter described, and pointed out in the claim.
The first part of the improvement consists in the application of heated air to the furnace, and the second consists in the adaptation of a series of checker-work flues or ducts formed in the masonry beneath the boiler and back of the bridge-wall, resulting in a complete commingling with the gases arising from combustion of heated air forced inward by the means employed as the first part of the improvement. 7
In the accompanying drawings, Figure 1 is a longitudinal section of a boiler and setting embodying our improvements. Fig. 2 is a vertical section on line 2 2 on Fig. 1, looking toward the checker-work. Fig. 3 is also a vertical section on line 3 3 on Fig. 1, having onehalf of the front remaining, looking into the furnace, showing the position of the air-injector. Fig. 4 is an enlarged sectional view of air-injector pipe.
A represents a boiler, and B a furnace with bridge-wall of the usual construction.
0 is a vertical pipe set in the front wall of the furnace, having a tapering nozzle pointing toward the bridge-wall. Near the lower end of the pipe Ois provided abranch pipe 0, extending underneath the grate and through the bridge-wall and open to the space back of the bridge-wall.
D is a steam fitted in the elbow at the top of pipe 0, having a spray-nozzle D pointing toward the opening in the pipe-nozzle.
V is avalve attached to the steam-pipe outside of the furnace-front for controlling the passage of steam.
In the space back of the bridge-wall underneath the rear half of the boiler is built a structure for commingling and burning the gases produced-by the combustion in the furnace, and consists of checker-Work of brick laid up in a manner to form vertical and horizontal passages e e. The horizontal passages are obstructed by intervening brick, so as to cause a retardation of the flames and enhance the commingling of air with the gases and produce a thorough combustion of the gases therein. The flames pass out of the rear passages into the chamber back of the boiler, thence to the flues in the boiler, as shown by the arrows. G is a baffle-wall built up from the rear end of the said checkerwork, and on which the rear end of the boiler rests, and thus the flames and gases are diverted from a direct passage to the rear of the boiler and are compelled to circulate beneath the boiler before being drawn downward into the checker-passages underneath the boiler. It will thus be seen that nearly the entire bottom of the boiler is exposed to the flames.
Underneath the checker-work the structure is provided with arched openings 0 0, 'connecting the spaces at the front and back of the checker-work, and from under these arches the hot air is drawn into the pipes O and C.
To the bottom end of pipe'C is provided a damper H, having a rod h projecting through the front,-by means of which cold air may be admitted to said pipe 0 when desired.
Having described our invention, we claim- In combination with a boiler-furnace of the checker-work situated beneath the rear half of the boiler and a short distance back of the bridge-wall and supported on arches open between the space back of the bridge-wall and g the space at the rear of the boiler,said checkerwork being also the same height as the bridgewall; a baffle-wall on the rear end of the checker-work supporting the rear end of the boiler; and a pipe 0 in the ash-pit, extendin g through the bridge-wall and in communication with the space back of the bridge-wall enhancing combustion, substantially as doand the arch under the checker-Work; a verscribed.
tical pipe 0 set in the front wall of the fur- Y nace and connected with the pipe 0 and profi' 5 vided with a nozzle projecting over the fire J and a steam-jet in said nozzle, the arrange- WVitnesses:
ment being such that hot air is injected over GEO. W. TIBBITTS,
the fire and commingles with the gases for LEWIS V. FORD.
