IMPROVEMENT m FEEDING AIR T0 FunNAcEs;
Specification forming part of Letters Patent No. 214,176, dated April 8, 1879 application filed January 30, I879.
To all whom it may concern Beitknown that I, JACOB V. Morrrnn, of New York, in the county and State of New York, have invented certain new. and useful Improvements-in FeediugHot Air to Furnaces, of which the following is a description.
My improvements are intended for use in connection with steam-boilersof the locomotive type, and especially vwithv the boilers of locomotive-engines.
These improvements consist in novel means whereby the heat escaping with the smoke and gases from the furnace of a'boiler may be effectively utilized for the purpose of heating air, the air so heated being. conducted to the furnace of the boiler, and by their commingling'with the gases produced by the-combustion of fuel in the urnace it enables the latter to be more thoroughly consumed than heretofore, andthreby effects a saving of fuel.
In the accompanying draWings Figure lrepresents a side elevation of a steam-boiler emb'ooyin g myimprovem'ents, parts being brokem awayto more clearly show my invention. Fig.. 2 re presents a transverse section taken on the dotted line a: on, Fig. 1.' Fig. 3 represents a transverse section on the "dottedline 3 3 ,'Eig. 1, the upper partef the'smoke-pipe being unsecti 'oned. Fig.4represents aplan-view of proper, through which air-may circulate. The v air absorbs by radiation a large portion'of the heat which wouldoth'erwise pass out. the smoke-stack and be wasted.
At the topof the smoke-stack I have shown Q a series of perforations, bfforming een,
O desi'gnatesthe smokethrough which air enters the air-space a, and v which prevents the entrance of cinders. In
orderto properly direct currents of air through this screen, I have represented the sm okestack as surmounted with a cowl or hood, F, which extends around a portion of its circumference, and by which the drafts or currents of air created by the rapid passage of a locomotive are deflected inward upon the screen. I may, if desirable, secure. this cowl or hood to the smoke-stack in such manner that it will revo'lve, so as to serve its purpose equally -well whether the locomotive is going ahead or backward. To conduct the heated air from the air-space a to the furnace of the boiler, I have represented ducts or passages G, arranged.
upon each side of theboiler, and preferably so as to be iuclosed'by the felting and lagging with which the boiler'is covered. Any num ber of these ducts orpassagesmaybeemployed.' and of anysize, as long as they are sufficient in area to conduct a proper amount of air to the furnace. They terminate in a distrib'uter, L, extending across the furnace, andprovided with openings 1 for the escape of air.
For the'purpose of still furtherutilizing the waste heat, 1 may arrange within the smoke- -box (J a petticoat, H, of funnel shape,
through which the exhaust 'steam escaping from the nozzle 0 passes, as clearly represented in Fig. 3. I may make this petticoat of a coil of pipe, provided with an inlet, dpfor air, and an outlet, 0, through-which heated air ,passes into the duct or passage G, as represented in.
.1 ig. .3, so asto produce a proper circulation of air through the petticoatyo'r, i'fdesirable, I may construct it of sheet metal, (as represented in Fig. 5,) having inside and Outside walls, between which is an air-space, connected with 'theai-r-space a by meausflo an inlet-pipe,
and'butlet-pipe'h. In some cases the jacket B may be dispensed with, and in such cases the inlet and outlet pipes g h would communicate directly with the furnace through the ducts or passages G.
As the combustion is. usually very rapid in the boilers of locomotive-engines, a large amount of heat escapes with the products f combustion. By my invention I enable a large proportion of this heat to ln'eabsorbe'dby the The combination, with the boiler of a 1000- motive-engine, of a pettiooat arranged within the smoke-box, surrounded by an air'jacket, nozzles for discharging steam through he said,
petticoat, an air-inlet pipe or passage to the said jacket, and a duct or passage fon con veying heated air therefrom to the fire-box of the boiler, substantially as specified.
JACOB V. MO'ITER.
