STEAM-BOILER FURNACE.-

:SPECIFICATION forming part'of Letters Patent No. 345,357, dated July 13, 1886.

Application tiled February 18, 1886. Serial No. 192,368. (No model.) i

To all whom t may con/cern:

Be it known that I, MILLS W. BARsE, a citizen of the United States, residing at Olean, in the county of Gattaraugus and State of New York, have invented certain'new and useful Improvements in Steam Boiler Furnaces, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in` furnaces for steam-boilers, and the object of my improvement is to produce a simple and inexpensive furnace in which a mixture of hydrocarbon gas and air can be used economically to heat steam-boilers of various forms. I attain these objects by the furnace and means illustrated in the accompanying drawings, in Which-- Figure lis a longitudinal vertical section through a furnace constructed in accordance with my invention, the ceiling of which is formed by the body of a plain cylindrical steam-boiler, supported horizontally upon the walls of said furnace. Fig. 2 is a transverse vertical section of the same. Fig. 3 is a longitudinal vertical section of a Isubstantially similar furnace supporting a iiue-boiler provided also with pendent tubes extending nearly down to the door of the furnace. is a transverse vertical section of the same.

The side and rear Walls, A, of the furnace are generally formed of bricks, and form` a substantially rectangular chamber, B, the floor Aj of which is either built solid, as shown in Figs. 1 and 2, or is made of large tiles or of cast-metal plates A3, as shown in Figs. 3 andi- 4, that are removably supported by the side walls, in which case there is a hollow chamber, At, under said plates large enough to admit men to unseal the lower end of the pendent tubes d and remove the mud that may possibly become collected therein. The boiler D is so supported by the walls of the furnace that its under side is only a few inches (more or less) above the door of the furnace. The front end of the boiler is supported by atransom, A', that also partly closes the opening in the front of the furnace. In this opening BL (preferably in the bottom thereof) is inserted one end of a pipe or pipes, C, through which Fig. 4,

is forced, by a fan -Wheel or other suitable means, a current of mixed air and gas, or of mixed steam, air, and hydrocarbon gas, or other combustible material, the furnace being specially adapted for use wherenatural hydrocarbon gas is obtained from gaswells andA used for heating purposes.

The pipe or pipes G are inserted in the opening B2, and the discharge of combustible material is parallel tothe sides of the furnace. The rush of gas from the end of the pipes C, when lighted, causes currents of heated air and gases that curl around the ,interior of the furnace, and becomes considerably packed and compressed in the rear portion thereof, and being drawn again into the dame from the pipe C they become highly heated and naturally rise against the boiler and follow its under side until they escape again through the front opening, Said opening may be provided with a door to be partly closed to retard the exit of the heated gases and products of combustion over its upper edge, and as it is important that nothing should be present to remove the pressure of gas from within the furnace, there is no chimney in Fig. 1 to vproduce a draft and useless waste of inflammable gases.

If it is desired to increase the heating-surface of the boiler it may be provided with one or more rows of the pendent tubes d. They are vertically partitioned to produce a current through them, and have a screw-cap at their lower end that can be removed to clean their interior when desired. The boiler may also ybe provided with horizontal flues D', to carry off the hot gases issuing from the front opening, B2, and to direct them into said flues, a

hood, D2, may be secured to the front end of the boiler, and the gases will escape naturally at the rear end ofthe boiler.

I do not claim, broadly, a furnace having av IOO above said chamber and forming a tight ceilan opening, B2., at the front to receive and ing therefor, said chamber having a closed discharge inflammable gases, and a pipe enrear end and an opening, B2, at the front, tering said opening to direct a currentV of in x5 substantially on thesame level with the floor flammable gases into said chamber, substan- 5 of said chamber, to discharge the products of tially as and for the purpose described.
