IMPROVEMENT 1N STEAM GENERATORS.
the 5x12211111: match it in this: Esters emu ant jgtjntg To ALL WHOM IT MAY CONCERN:
Be it known that 1, WILLIAM L OWE, of Bridgeport, in the county 'of Fairfield, and State of Connecticut, have invented a new'a-nd useful Improvement in Steam Boilers; and I do hereby declare that the following isaa full, clear, and exact description thereof, which will enable others skilled in the art to make and .use the same, reference being bad to the accompanying drawings, forming part of this specification.
The object of this invention is to improve what is known as the horizontal tubular or flue boiler and it consists principally in forming a combustion-chamber within the shell of the boiler, directly over the fire, and in forming openings through the boiler, in the manner hereinafter described.
Figure 1 represents a side view of the boiler set in an arch of masonry, with one wall of the arch removed, showing the combustion-chamber in dotted lines, and an aperture through the bottom.
Figure 2 is a vertical section of the'boil'er' through the line :0 a of fig. 1.
Similar letters of reference indicate like parts.
A represents a boiler of the ordinary kind, with tubes running through its water-space in the usual manner, B is the combustion-chamber. As this kind of boiler is ordinarily constructed the fire is made upon the grate O, and the products of combustion pass to the back end of the boiler and then return through the tubes or fines to the front end, the fines-or tubes in such cases extending entirely through the' boiler. Aproper and complete combustion ofthe gases cannot be obtained in that manner. A large portion of the heat thus "generated is absorbed by the wallsof the arch enclosing theboiler, a-nd a large portion of the combustible gases passes of? unconsnmed, because it is not and cannot well be supplied with the requisite quantity of air while in its most highly heated state. In the construction of my boiler I provide a. remedy for this defect by forming a combustion-chamber within the boiler, as seen in the drawing. The communication between the chamber and the furnace is through apcrturesD in the bottom of the boiler, as seen in the drawings. These'apertures may be more or less in number, and of sutficient size to allow the products of combustion to freely pass into the chamher. This of course they do when in a highly heated state, and being, while in the chamber, mixed with the required quantity of air, (or oxygen,) perfect combustion ensues, and a blaze passes through the tubes or fiues of the boiler instead of a current of unconsumcd gases. a represents the tubes of the boiler inthis example of my invention. These tubes pass through the boiler from thclback part of the combustion-chamber,and the products of combustion are returned from the back end of the tubes, down and under the shell of the boiler,
intojthe chamber E, from whence they are conveyed to the chimney. F is a wall at the back of the furnace. G is the furnace door. H is a door which gives access to the combustion-chamber, and through which air is admitted. J is a supporting wall, a side View of which is seen in fig. 2 in dotted lines. K is aplate, by which the products of combustion are forced to descend at the back end of the boiler. L is a door-way through the back wall, to giro access to the fines or tubes for cleaning or other purposes.
It is a well-ascertained fact that those boilers which are the most effective as steam generators are those where the heated products of combustion are first made to pass through the fines or tubes and then returned under the boiler.
Having thus described my invention, 1 claim as new, and desire to secure byLetters Patent- Constructing cylindrical boilers, commonly known as plain horizontal tubular or flue boilers, with one or more openings in the sides or bottom of said boiler, which shall communicate with a combustion-chamber inside of the boiler, and connected by tubes or lines with the back end of the boiler, through which the products of combustion are made to substantially in the manner and for the purposes herein shown and described.
