PETER L. VVEIMER, (5F LEBANON, PENNSYLVANIA.
BOILER-FURNACE.
SPECIFICATION forming part of Letters Patent No. 240,869, dated May 3, 1881.
Application filed October .19, 1880. (ModeL) To all whom it may concern Be it known that I, PETER L. WEIMER, of Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Boiler-Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
This invention relates to that class of boilerfurnaces which utilize the waste gases of blastfurnaces as fuel, the steam which is generated being employed to create the air-blast for the blast-furnace.
Heretofore furnaces of this description have had their combustion chambers respectively provided with either one or two inlets for feeding the gas into said chambers. If a combustion-chamber has two gas-inlets, they are located in a horizontal line below the lowest row of boilers; if one inlet only is provided,
it is located at a central point in a line below. 1
the boiler. In either case the gas is not introd uced into the combustion-chamber at numerous points respectively between the different boilers, so as to result in a uniform temperature throughout thecombustion-chamber. Hence the lowest row of boilers are exposed to an intense action of the flame, and the upper row of boilers receive a much less degree of heat. The lower boilers are not only much nearer the flame, but they also, to a great extent, cut off the flame from impinging against the upper boilers.
The object of my invention is to obviate the above disadvantage and introduce the gas equably into different portions of the combustion-chamber.
To this end I provide numerous gas-inlets, connecting with the combustion-chamber at different horizontal and vertical points thereof, and. adapted to be independently controlled. These inlets discharge gas into the combustion-chamber at such points as to result in a more equable temperature throughout the area of said chamber. The upper row of boilers are subjected directly to impinging flame, and are acted upon by intense heat.
The drawings represent the invention as cmbodied in one form ofconstruction, so inuoh only of a furnace being shown as is necessary to understand the improvement.
Figure 1 is a view, in front elevation, of one end of a boiler-furnace. Fig. 2 is a transverse vertical section of the furnace, showing, in side elevation, the end wall provided with the gas inlets. Fig. 3 is a detail view, taken in avertical plane through one of the vertical series of connecting-pipes.
An exterior gas-main, A, extends, longitudinally with the end wall, B, of the combustion-chamber, in which the boilers are located. At different poi-n ts in the length of the main upright pipes 0 connect therewith. Each of these pipes is provided with upper and lower branch pipes, D, which extend horizontallyto the furnace. The chamber-wall is provided with numerous gasinlets,E,through which the pipes discharge their contents into the combustion-chamber. These gas-inlets are at different horizontal and vertical points of the combustion-chamber, one series of the inlets being in a horizontal line below the lower row of boilers, and a second series of inlets being formed in a horizontal line between the upper and lower rows of boilers. The branch pip'es are respectively provided with valves a, so that gas can be introduced in greater-or less volume, or cut off entirely, as be desiredh for each of the inlets.
The foregoing specification describes the details of one form of construction for carrying out the principle of my invention; but modifications, changes, and substitutions of parts may be made, provided the essential features of invention set forth in the following claims are employed.
Iam aware that inflammable gases have been injected directly into the tubes of a tubular boiler; also, that air and air and steam and steam and hydrocarbons have been introduced at different points in the fire-box of a steamgenerator; and hence I wouldhave it understood that I make no claim to such construction and arrangement of parts.
Having fully described my invention, what I claim as new, and desire to secure as Letters 7 "Patent, is-
IOC
ing connected with the gas-main, substantially as set forth.
3. In a boiler-furnace, the combination, with a combustion-chamber and a series of boilers, constructed and arranged substantially as shown and described, of a gas-main, a series of pipes leading therefrom to difii'erent points in the wall of the combustion-chamber, and 20 valves for regulating the flow of gas in said pipes, substantially as set forth.
In testimony that 1 claim the foregoing I have hereunto set my hand this 23d day of October, 1880.
