1'0 (all 1071 0112, 'iz'; may concern:
Be it known that I, GEORGE W. PHILLIPS, a citizen of the United States, residing at Buena Vista, in the county of Rockbridge and State of Virginia, have invented new and useful Improvements in Steam-Boiler Furnaces, of which the following is a specification.
This invention relates to a steam-boiler furnace, and particularly to an organization of elements for economizing in the use of fuel and to obtain the greatest amount of heat where it is most needed to produce a greater amount of steam than can be obtained with the amount of fuel ordinarily used.
The improved furnace organization includes an auxiliary furnace for generating gas by burning tan from extract wood, tan from tanb ark, or any other fuel placed in the auxiliary or gas-generating furnace. From this latter furnace the gas is conveyed through a conduit to an intermediate portion of the boiler and in rear of the ordinary boiler-furnace and is consumed by the fire from the said boiler-furnace. By this means very little fuel will be wasted by gases escaping through the gas-stack.
The drawing illustrates a longitudinal vertical section of a steam-boiler furnace, showing the improved. auxiliary gas -generating furnace in connection therewith.
The numeral 1 designates the brickwork or frame of an ordinary steam-boiler furnace having a grate 2, a bridge-wall 3, and a feedopening 4. Above this furnace and extend ing longitudinally through the brickwork or frame is a boiler 5, and through the medium of suitable passages in the present instance communicating with the rear and front of the boiler 5, as at 6 and 7, and with an outletconduit 8 the products of combustion and particularly the ignited gases, which will be hereinafter more fully explained, are first di rected rearwardly under the boiler, then for wardly through the latter, and any unconsumed residuum or products of combustion pass out through the conduitS and an opening 9 into a suitable stack. The furnace, except in the particulars which will be presently set forth, is of ordinary construction, and the boiler is set therein by any of the well-known means and may be of any suit able type of flue-b oiler.
In advance of the front of the furnace and below the latter is a gas-generating furnace 10, having any suitable grate construction and adapted to be fed withfuel through openings 11 or otherwise, the said openings being formed in a roofing 12, having protective coverings 13 thereon and providing a floor at the front of the furnace 1. The furnacc 10 has suitable openings 14 for removing ashes, and connecting with one extremity of said furnace 10 is an upwardly-inclined fiue or conduit 15, having a cleaning-opening 16 communicating therewith and terminating immediately in rear of the bridge-wall 3, and having an auxiliary or supplemental bridge-wall 17 which operates to throw the gas generated in the furnace 10 upwardly against an intermediate part of the boiler 5.
A fire is started on the grate 2 of the furnace 1, and as thegas is generated from suitable material ignited in the furnace 10 it passes up through the flue or conduit 15 and is ignited in the rear of the bridge-wall 3 by the fire on the grate 2, and an intense heat results by using but very little fuel on the said grate 2, thus economizing in the use of fuel. The ignited gas passes under the boiler rearwardly to and through the passage 6 and then into the flues of the boiler and forwardly through the passage 7, and the products of combustion or unconsumed residuum passes out through the conduit 8, as hereinbefore set forth. It will be understood, however, that very little residuum will result by reason of the fact that the gas generated in the auxiliary furnace and fed in the rear of the grate 2 will be almost entirely consumed, and at the same time any products of combustion passing over the bridgewall with the flame from the grate 2 will be consumed and utilized as heating means or to increase the heating capacity of the furnace.
It is preferred from the standpoint of economy to use cheap or refuse material in the furnace 10; but it will be understood that coal or any gas-producing fuel may also be employed, if desired. The improved gasgenerating furnace can be readily applied in operative relation to anyfurnace now in use by a very simple modification, and the expense attendant upon such application will soon be obliterated by the saving in fuel by the use of this auxiliary furnace.
The advantages of the furnace are manifold; but, as heretofore indicated, the prinwall and under the latter projecting up wardly at an angle of inclination and ver. tically contracted adjacent to the bridgewall, the portion of the conduit passing through the bridge-wall being of greater dimensions than the said contracted portion thereof, whereby the gas may be driven u wardly through the bridge-wall in rear of tl fe grate of the main furnace with greater force.
In testimony whereof I affix my signature in presence of two witnesses.
GEORGE W. PHILLIPS.
