GUSTAV WOLF, OF NEW YORK, N. Y.
BOILER-FURNACE.
SPECIFICATION forming part of Letters Patent No. 781,580, dated January 31, 1905. Application tiled June 27, 1904. Serial No. 214,292.
To 117/ ll'Zl/Jlll if 711/! ('(JIH'PT/b. I Be it known that I, GUSTAV \VoLr, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, i in the county and State of New York, have I invented a new and Improved Boiler-Furnace, of which the following is a full, clear,
and exact description.
This invention relates to iinprovements in attachments to tubular steam-boilers for supplying air in a heated condition to the boilerfurnace for promoting combustion and the burning of the gases. In certain devices for this purpose the air so admitted as to pass off with the draft through the combustionchamber, and therefore does not effect the purpose designed.
It is the object of my invention to provide a boiler attachment so arranged as to practically direct hot air into a portion of the comlmstion-chamber, causing a thorough mixture with and a complete burning of the gases, rcsultingin intense heat, and consequently an economy in fuel.
I will describe an air-supply attaclnnent for boilers embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar characters of referenceimli cate corresponding parts in all the figures.
Figure l is an elevation, partly in section, of a steam-boiler and an air-supply device embodying my invention attached thereto. Fig. 2 is a front elevation thereof, partly in section. Fig. I) is a perspective view of the attachment, and Fig. I is a similar view of a modilicd form of the attachment.
The attachment comprises a boxing 1, which takes the place of the brickwork in the front of the crown-sheet, and this boxing is provided with a small air-inlet chamber .2 and a dischargecliamber 3, said discharge-chamber being provided in its inner wall with perforal tlous I. through which the air passes to the fuel overthe grate. The small inlet-chamber 2 is provided with an opening in its front wall, which is regulated for the admission of air by a damper A circulating and heating pipe 6 is arrai'iged between the header 7 and the front flue-sheet 8, and one end of this pipe communicates with the chamber 2, while the other end connnunicates with the chamber 3. Also leading from the chamber 3 are discharge-rapes 9, having nipples 10, designed to engage air-tight into the front ends of lower boiler-tines II.
In the. modilication shown in Fig. I the attachment comprises a practically continuous pipe 12, which has enlarged upper and lower portions 13 II, and from the portion I-t pipes 15 16 lead to connection with boilerflues, as before described, and also leading from this lower portion It is a tube IT, having branches 18, provided with discharge-nipples It). The air is admitted from the outer side of the furnace through the end Qt) of the pipe.
In the operation the atmospheric air will be caused to circulate through the heating device at the front end of the boiler-tines, and a portion of the air will pass into the combustionchamber over the grate, and a portion of the air will pass through the fines to the rear end of the combustion-chamber and mingle with any gases that may not have been burned by mingling with the air admitted at the front.
It is obvious that a device embodying my invention may be readily applied to any boiler, of course the size of the device being in accordance with the size of the boiler.
Having thus described my invention, I. claim as new and desire to secure by Letters Patent I. In combination with a tubular boiler and furnace, a circulating-pipe arranged between the front tlue-sheetand the front header, means for directing atmospheric air into said pipe, means for directing air from said pipe into the front portion of the furnace, and means for directing air from said pipe to the rear portion of the combustioil-chamber.
2. In combination with a tubular boiler and furnace, of a boxing arranged in the crownsheet of the furnace and having perforations in its inner wall for discharging air over the furnace-grate, the said boxing having an inletchamber and an outIet-chamber, means for regulating the admission of air to the inletchamber, a circulating-pipe arranged between the front flue-sheet and header, the said pipe communicating at one end with the inlet-chamber and at the other end with the outlet-chamber, and means for directing air from the outlet-chamber to the rear portion of the combustion-chamber.
3. In combination with a tubular boiler and furnace, a boxing arranged in the crown-sheet and divided into an inlet-chamber and an out-' 4. The combination with a tubular boiler and furnace,of a boxing arranged in the crownsheet and divided into an inlet-chamber and an outlet-chamber, the inner wall of said outletchamber having perforations, the outer wall of said inlet-chamber being provided with an opening, a regulator for said opening, a circulating-pipe arranged forward of the boilerflues and communicating at one end with the inlet-chamber and at the other end with the outlet-chamber, and pipe connections between said outlet-chamber and two of the lower boiler-fines, whereby air is admitted to the rear end of the combustion-chamber.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
