FURNACE FOR STEAM-BOILERS.
SPECIFICATION forming part of Letters Patent No. 276,903, dated May 1, 1883.
(No model.)
lo all whom it may concern:
pipe, and, the pipe being located considerably Be it known that I, JOSEPH G. SEXTRO, a below the grate, steam will be supplied in sufcitizen of the United States, and a resident of ficient quantities to all parts thereof, though Carthage, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Means for Preventing Smoke and Promoting Combustion in Furnaces, of which the following is a specification.
The object of my invention is a cheap and convenient means for increasing the draft. promoting combustion, and preventing smoke in furnaces, and thus economizing fuel. These objects are attained by the means illustrated in the accompanying drawings, in which- Figure 1 is a longitudinalvertical section of a furnace provided with my improvements. Fig. 2 is a transverse vertical section of the same, taken through linear to of Fig.1, looking to the front of the furnace.
Similar reference-letters indicate like parts wherever they, occur.
To illustrate my invention I have selected a steam-boiler furnace of ordinary construction, as this is thecharacter of furnace to which I have successfully applied it in use and fully demonstratedtits practicability and usefulness. The masonry of the furnace is represented by letter A. .15 is an ordinary twoflue boiler, set in the usual manner. 0 is the fuel-chamber, and D the ash pit or chamber underneath the grate-bars E. Across the 'chamber D, a short distance below the gratebars and back of the furnace-front, is located 1 a perforated pipe. This pipe passes through the side walls of chamber l), and outside of the walls is provided with valves G H. The
valve G controls the supply of waste steam to pipe F, which is supplied through pipe J, which is connected to the exhaust-pipe of the steam-engine. The valve H upon the opposite side controls the communication between pipe F and a waste-pipe. (Not shown.) The perforations in pipe F are made at or about an angle of forty-five degrees with relation to the top of the pipe, so as to discharge in the direction of the center of the grate-bars. Thus arranged, the; are less liable to be clogged with ashes than if made along the top of the the greater portion of the steam will be directed against the grate at about its center, and in the direction of the draft. I have shown in Fig. 2 a line of these perforations; but this arrangement may be varied, or two or more lines of perforations used; or the pipe may be perforated with fine slits to discharge the steam in thin sheets instead ofjets. The pipe F, located as shown, becomes highly heated by the fuel upon the grate-bars, and the waste steam passed into it is therefore greatly expanded and discharged through the perforations with considerable force. Instead of a single pipe, as F, several may be used, but should be located from six to ten inches below the grate-bars.
I have found by experience that jets of steam, admitted below the grate-bars, as in my furnace, not only promote combustion and prevent smoke, but entirely prevent the formation of clinkers upon the grate-bars, and they therefore last much longer.
lam aware that it is old to construct a boiler-furnace with a supplementary grate arranged in rear of and a little below the ordinary grate, said supplementary grate having an individual ash-pit, (isolated from the front. ash-pit,) in which was arranged a perforated pipe for admitting exhaust-steam to said supplementary grate, and this arrangement I do not claim.
I claim as my invention- A steam-boiler furnace having a single firechamber, a single grate, and a single ash-pit, in combination with the perforated pipe F, extending across the forward end of the ash-pit a little distance below the grate, and the pipe J, communicating only with the waste-pipe of the engine and with pipe F, all arranged substantially as described.
JOSEPH G. SEXTRO.
