Application filed April 20. 1907. Serial 1%. 3691247,
State of llcnnessee, have invented a new and improved Smoke Consuming Furnace, of which the .iol'lo'wing is a lull, clear, and exact descri tion.
The invention relates to smoke consuming furnaces such as shown and described in the Le tors .l stent of the United States, No. %,999 end No. 784,3;2l granted to me on lrlorch 22, 1904 and lilsrch 7, 1905, respectively.
'lfho object of the present invention is to provide it new and improved smoke consummglurnccc arranged to produce a. high heat end complete combustion by the burning of s mixture of air and producer or water gas, the h being obtoined ly superheoting the stcinn to dissociation and passing the disgen and hydrogen in line jets socisiicd o. into. t .o products of combustion arising lrom the burning fuel in the lire box, the on being highly hosted before entering the lire box and reaching the producer gas.
The invention consists cl novel fentiu'es and ports :ind combinations of thc smne, which will be more fully described hereinafter and then pointed out in the claims.
,A practical embodiment of the invention is represented in the accompanying druwings forming .1. part oi this specification, in which similar characters of reference indicate correspending ports in oil the views.
AS illustrated in Figs. 1,2 and 3, the boiler A is set in the usual manner in a. brick-Work B containing s the be); C having a. grate D, below W 1 d on ssh pit E, eccess being" llftfl. to the solo .irc beta (3 and ash pit E by suitable doors c and At the rear end of the fire box i1 is arranged a bridge wall F having a checker-work top l behind which is the combustion chamber G leading to the rear end of the boiler A, to direct the heated gases into and through the lines of the boiler A in a forward direction, so that the gases finally pass into the stock A.
In the front upper portion of the fire box -O are arranged sir chambers .l'l and H formed by spaced concentric arches H and H extending from the side walls of the brickwork 5, the top of the upper srch H being spaced from the under side of the boiler A, to leave the letter unobstructed at this point and thus maintain it full hosting; surfs-cc of the boiler throughout the length thereof. The lower arch ll" extends shove the door C so as not to obstruct the entrance to the lire box 0. A longitudinally extending portition ll is arranged b'etii'een the arches H and H, to form the two chambers H and H, one alongside the other, and the outer ends of the sold chambers H and ii .re connected by air ducts l and 1 with the ssh pit E, the said ducts extending through the side Walls of the brick-work B, as plainly indicated in Fig. 2. Thus air from the ash pit E pass up through the ducts l and i into the chembers I1 and H, the air being hosted in its passage by passing through the hosted ducts contained in the side Walls of the brick-Work. B, and by passing into the chambers H and H is further heated by the red hot fire b ick Wells of said air clnirnbcrs. The entrance ends to the ducts l and I are provided with suitable dampers P, to permit of controlling the amount of air passing up into the chembers H and H Within the air chambers H and H are orrsinged the steam dissociating blowers J end J", each preferably in the form of it flat casing p of cast iron or the like, and provided at its bottom with lugs J resting on the top surface of the arch H so as to suppprtesch dissociating blower J and J freely within the corresponding chamber H or H, to permit the air to pass completely around the said dissociating blower J or J. The front ends of the steam dissociating blowers J and J are connected by pipes .bl having valves K, With the steam dome A? of the boiler A, so as to ollow the steam to pass into the said dissociating blowers, with it view to best the steam to such. an extent thst it readily dissociates into its constituents hydrogen and oxygen, the dissociated steam passing out of the blowers J and J at their rear ends througl'i jets J located in the outlets H of the charm 5 bers H and'H, as plainly indicated in Fig. 'l. The jets J are formed in such a manner as to direct the dissociated steam through the products of combustion arising from the v burning fuel on the grate D and also to direct w the said dissociated steam towards a gas bench L arranged in the rear of the grate l) at the front side of the bridge wall F.
By reference to Fig. 1, it will be seen that the inner end oi the upper arch H projects a 5 distance beyond the inner end of the lower arch H, so that the heated air passin from either chamber H or H to the out et if readily commingles with the dissociated steam issuing from the jets J so as to be 29 forced with the dissociated steam in the direction of the gas bench L.
In order to prevent the mixture of air and gas striking the side walls of the firebox. O, [the inner ends of the air chambers H and H are provided at their sides with lire bricks HF leading to the outer side of the corregpondin steam dissociating blowers J and e, as will be readily understood by reference to Fig. 8. New by the arrangement de- 30 scribed a large heating area is provided in each blower J and J, to insure a dissociation of the elements of the steam, and the disso'ciated steam in' passing through the pro ducts of combustion arising from the burning fuel in the fire box U causes a production ol. producer or water gas, and the heated air coming in contact with this producer or wa tcr causes a burning thereof, at the same time develo ing a high heat and utilizing the 40 burning fuc to the fullest advantage by insuring complete combustion thereof, The 'fiaine in passing through the checher work top F is comminuted or chopped up into small, thin tongues, and consequently a perfeet combustion is obtained.
By reference to Fig. 1 it will be noticed that the inner or jet end of the dissociating blower J or J is set back slightly l'rom the inner end. of the lower arch. ll, so as to pre- 50. vent exposure ol' the jet end ol the blower to l the products of combustion arising from the burning .lucl in the lirc box C. a
The jets J are preferably arranged. in fan shape in a transverse direction, so as' to spread the dissociated steam in tho lire box (J, to insure a complete commingling of the dissociated steam with the products of combustion arising'lrom the burning 'l'ucl. By
directing the dissociated steam downward- I "lu'e box being provulcd' \Vltll alr ducts lcad- 30 and rearward towards the gas bench L, the mixture after im )actwith the gas bench L is deflected upward further intimate commingling of the constituent parts of the gas. it is understood 35 that as the s bench L tends to send the by the gas bench, to insure ward to and through the rear end of the grateand burning the same.
Althougl'i I have shownand above described. the improvement in relation to a horizontal tubular boiler, it is evident that the device is readily applicable to furnaces of various types. For instance, as shown in Fig. at, the device is applied to a water tube boiler of the Heine type, and as shown in Figs. 5 and 6, tea similar boiler O of the Babcock do Wilcox type, and in Fig. 7 is shown a vertical water tube or tubular boiler P provided with the improvement.
In the forms illustrated in Figs. 4, 5 and 6, the steam dissociating blowers J, Jfit with their upper faces against the under side of the top arch H, but otherwise the construction of the device is the same as above described, in reference to Figs. 1, 2 and 3.
Although I have shown the intake of the air duct 1, I as coming from the ash )it E, it is evident that I do not limit mysc arrangement, as the air ducts may be otherwise arranged, as, for instance, shown in my last patent above referred to.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A furnace comprising a fire box and a plurality of concentric spaced arches at the front of the lire box, a dividing wall arranged longitudinally between the arches and dividing the space into two compartments, said lire box being provided with air ducts leading from the ash pit to the'compartments and a 'disassociator in each compartment, said disassociator comprising a casing of rela tively great length and of relatively small depth and being provided with a steam inlet pipe, and a series of outlets at its rear end,
said outlets being directed downward and backward, whereby to direct the disassociatcd elements of the steam through the burning gases of the fuel, said iirc box having a gas bench against which said products are directed, said bench being inclined forwardly and downwardly to deflect said products upwardly through the burning gases,
said lower arch boing'incliued downwardly at its rear edge, and the upper arch projecting beyond said inclined. portion for the purpose set forth.
