S. PERRY HOLMES AND -HENRY SIEBEN, OF BURLINGTON, IOWA.
STEAM-BOILER FURNACE.
SPECIFICATION forming part of Letters Patent No. 430,955, dated June 2%, 1890. V
Application filed April 7, 1890. Serial No. 346,914. (No model.)
To all whom it may concern:
Be it known that we, S. PERRY HOLMES and HENRY SIEBEN, both residents of Burling ton, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Steam-Boiler Furnaces; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in apparatus or devices for feeding steam and air to steam-boiler furnaces for the purpose of promoting combustion therein.
The invention consists in the novel con struction and new combination ofv parts hereinafter fully described, and specifically pointed out in the claims.
In the accompanying drawings, Figure 1 is a front view of a steam-boiler furnace constructed according to our invention, the front wall being removed. Fig. 215 a top view of the same with the boiler removed. Figs. 3 and 1 are detail sectional and plan views, respectively, of one of the superheated steamnozzles.
In the said drawings, the reference-numeral 1 designates the side walls of the furnace; 2, the rear wall thereof, and 3 the top or arch.
4 designates the boiler, having steam-dome 5. These may all be of any ordinary or suitable construction.
6 designates the bridge-wall, of ordinary height, located near the rear end of the furnace, so as to form with the rear wall 2thereof the gas-chamber 7. This wall is provided with a number of spaces 8 between the bricks,
forming channels for the passage of the blaze from the fire-chamber 9 to said gas-chamber,
in order to insure combustion of the products contained therein.
10 designates the center wall, extending back to bridge-wall 6 and up to fire-brick arch 12. This center wall is provided with channels or passages, so that the chambers on each side thereof communicate with each other for the purpose of preventing cooling of the furnace when either door is opened for firing.
12 is the arch under the boiler and over firebox, with openings on either side of center under the boiler.
Leading from the steam-dome 5 is steampipe 14, communicating with superheater 15, which consists of a cylindrical or other suitably-shaped vessel incased in the wall of the furnace next to the fire-box or in close proximity thereto. This pipe is provided with stop-cock 16.
The numeral 17 designates the vertical airtubes, having bell-mouths 18, which supply air to the horizontal hot-air pipes 19 19 and transverse pipes 20, these pipes being connected together and with said air-tubes 17. At suitable intervals pipe 20 is provided with openings having flaring or hell mouths 21, communicating with the fire-box, while pipes 19 are provided with similar mouths opening into the gas-chamber 7.
22 designates a superheated steam-pipe leading from the superheater and located within and surrounded by the pipes 19 19 and 20, (shown in dotted lines,) which are made considerably larger in diameter for this purpose. At the bell-mouth openings 21 of pipe pipe 22 is provided with a short projecting arm or tube 23, having a nozzle 24, which is flush with the outer end of said bellmouths, as shown. At the bell-mouth ends of pipes 19 said pipe 22 is provided with similar nozzles.
25 designates a Waste-pipefrom superheater, provided with stop-cock 26.
27 designates the fire-grate, and for the purpose of still further promoting the combustion in firebox, we provide pipe 28, lead ing from pipe 14: and passing under said grate, where it is provided with a number of jetnozzles 29, through which steam is forced into the bed offuel on said grate.
The operation of the apparatus will be readily understood. Steam being supplied from the superheater to pipe 22 will escape with great velocity through the nozzles 24, thus creating a vacuum in the vertical air-pipes, which will cause air to enter therein and to circulate in pipes 19 and 20 and be discharged in a heated state through the bell-mouths 21 and commingle with the superheated steam from pipe 22.
Having thus described our invention,what we claim is 1. In a steam-boiler furnace, the COIItblllta tion, with the grate, boiler, steam-dome, and supply-pipe, of a superheater incased in the furnace-wall next to the fire-box and communicating with the steam-dome through said supply-pipe, vertical air-tubes, transverse and horizontal air-pipes connected with said airtubes and provided with bell-mouth openings, a superheated steam-pipe from the superheater located within the air-pipes and having nozzles at the bell-mouth openings in said air-pipes, and a steam-pipe leading from the steam-supply pipe and having jet-openings under the fire grate, substantially as described. 2. The combination, in a steam-boiler furnace, of the grate, the boiler having dome and supply-pipe leading to a superheater incased in the furnace-Wall next to the fire-box, thebridge-wall 6, having openings 8, the com-- bastion-chamber 7, the center wall 10, and
arch '12, provided with channels oropenings, the vertical air-tubes, the transverse and horizontal lair-pipes having bell-mouths opening, respectively, into the fire-box and combustion-chamber, the steam-pipe 22, having nozzles 24, and the pipe 28, having jet-nozzles 29, substantially as described.
In testimony that we' claim the foregoing as our own We have hereunto affixed our signatures in presence of two witnesses.
S. PERRY HOLMES. HENRY SIEBEN.
