Letters Pate/nt 87,279, dated Febfrua/ry 23, 1869.
MPROVEMENT -IN' .STEAM-BOILER PURNACES.
The Schedule referred to in these Letters Patent and making ps rt of the same.
. Be it known that I, ISAAC MORGAN, of Quincy, in the county of Adams, and State of Illinois, have invented a new and useful Improvement in Furnaces; and I do herebydeclare that the following is a full,
clear,a nd exact description thereof, which will enable others skilled in the art to make and use the same, reference. being had to the accompanying "drawings, forming part of this specification. A
I This invention has for s object, to consume the gaseous products of combustion, escaping from the fur-v naces of' steam and other boilers, and consists in the .arrangement of a partition over the end of the bridgewall, and a' series of hot-air` tubes between the boilers, and projectingA slightly through the partition, whereby the gaseous products of combustion are directed in a broad sheet thro'ugh the contracted throat formed by the bridge-Wall and partition, and, mingling with the intensely-heated air from the tubes, are consumed.
Figure 1 represents a longitudinal section of a steamboiler, through the line x x, g. 2.'
Figure 2 is a front view of the furnace, showing the boilers in position, but with the front plate removed.
Figure1 3 is a vertical cross-section, through the line y y, fie Similar lettersoi' reference indicate like parts.
-A represents the boilers, 'which are of that class known as fluefboilers.
B representsthe fines. C C are supports, under the front end of the boilers. I) (iig. 1) represents .the grate-bars. E is the bridgevwall.
F is the'ash-pit. G is the combustion-chamber, and H is the smoke-chamber. J represents a transverse plate or partition, which fills-up the'space between the boilers, the outer sides .of the boilers, and the wall, so that the upper line of the narrow throat K, beneath the boilers, is parallel with the top' of the bridge-wall its entire length.
At the front end ofthe'boiler, directly over the fur- Y nace, there are three or more air-tubes L, which convey heated air into the combustionchamber G.
It is well known by those who are acquainted with the subject, that where there' is nota suiicient quan' tity of atmospheric air or oxygen) supphed tothe burning fuel, carbonic-oxide gas is the result, which gas.
passes off and escapes from the ordinary chimney, car-4 rying with it large amounts of y carbon unconsurned.
'This gas is, ofcourse, generated at a high temperature, and if, when vat that temperature, it is supplied with an additionalY quantity of oxygen, its carbon is consumed, and fuel saved. This ladditional quantity of oxygen I supply through the aiitubes L.
These tubes, it will be seen, pass over the fire at the front end of the boiler, and project slightly throughthe partition J, above the throat K consequently they are kept red hot, so thatthe air whichpasses through them becomes intensely heated before it is discharged into the combustion-chamber.
The operation is as follows: The gaseous products of combustion rising from the furnace D, impin ge against the wall between thev boiler and sides enclosing them, and are thence directed in. currents tothe partition J, which' deflects them in a broad sheet through the contracted throat K, at which point they are met by the intensely-heated air from the tubes'L, and consumed'.
Thetubes L, atl the rear end of the boiler, are used simply as a means for*` inspecting the interior of the combustion-chamber.
I am 'aware that air has been introduced to the combustion-chamber of steam-boilers, through and also imf mediately behind the bridge-vialL-by means of pipes, or by openings in the bridge-wall, or behind it; but such arrangements I do not' claim, as they do not permit the heated air to thoroughly mingle with the gaseous products; but
What I do claim, and desirel to secure by Letters Patent,1is.
The described arrangement of the partition J and hot-air tubes L, with relation to each other, the bridgewall, the furnace F, and the boiler A, for the purpose specified.
ISAAO MORGAN.
