SMOKE-CONSUMING FURNACE AND APPARATUS IN CONNECTION THEREWITH.

SPECIFIGATION forming part of Letters Patent No. 678,261, dated July 9, 1901. Application filed December 24,1397. semi No. 663.356. (NomodelJ subject of the Emperor of Austria, residing in the city of Vienna, in the Province of Lower Austria, in "the Empire of Austria-Hungary, haveinvented certain new and useful Imp'rovements in Smoke-Consuming Furnaces and Apparatus in Connection Therewith, (for which I have obtained patents in Germany,No. 91,332, dated February 15, 1896; in' France, No. 259,035, dated August 20, 1896; in Austria, No. 46] 3,083, dated August 3, 1896, and in Belgium, No.127,365, dated April 3, 1897,) of which the following is a specification.

ing furnace .and apparatus in connection therewith; and the object of the invention is to unite-i-n such a furnace a rational supply of air with a very high temperature, so as-to permit of a great working capacity within considerable range. 4

The invention consists of certain features of construction and combinationsof parts, to be hereinafter described and'then particularly' pointed out in the claims.

In the'accompanying drawings, Figure 1 is a vertical longitudinal section. Fig. 2 is a crosssection. Fig. 3 is a horizontal section. Fig. 4 is a front elevation, and Fig. 5 is a side view, of an ordinarycylinder-boiler provided with my improved smoke-consuming device. Fig. 6 is a'vertical longitudinal section. Fig. 7 is a cross-section through a ship-boiler with such a firing. Fig. 6 is a vertical longitudinal section, and Fig. 7 is a cross-section, of a flame-flue with my improved smoke-consuming device. Fig. Sis a vertical longitudinal section of a locomotive, partly in section, through the fire-box. Fig. 9 is a cross-section ofthe same. Fig. 9 is a front elevation of the same. .Fig. 10 is a front view of the fire-door". Fig; 11 is a transverse section of the same.' Fig. 12 is a horizontal section thereof, and Fig. 13 is a detail view of a part thereof. Fig. 14 is a vertical longitudinal section; and Fig. 15 is a from elevation of a water-tube boiler of the Babmgck and Wilcox type, and Figs. 16 and 17 are respectively a detail cross-section and a side levation of the pipe connection leadin i'tothe waterchamber of the door at the ehds of the flues.

Similar letters of reference indicate corresponding parts.

To prevent the transmission of heat by radiation during the formation of the heatinggases to the surrounding watermoistened walls of the furnace, which would causealowering' of the temperature therein, the rearwardly and downwardly sloping arches a over the fire-chamber are made of fire-brick or other suitable non-conducting material, such as fire-clay, silicate of magnesia, Dynas brick, and the like.

Below the grate and at the sides of ,the ashpit A are arranged air-channels b,'Figs. 1, 2, Th s invention relates to a smoke-cousum- 3, and 14, which are separated from the ashpit by means of iron side plates 1). The airchannels bare arranged under the walls of the fire-chamber and to one side of the space occupied by the fire-chamber, so as to have an ash-pit undiminished in size. The object of said air-chan nels is to utilize the high temperature of the air under the grate for preliminarily heatingv the secondary air which passes through said channels and to improve the durability of the grate by the simultaneous cooling of the ash-pit. The said iron .plates I) very quickly take up the heat radiating downward from the grate and impart the same to the air circulating in the side air-channels b, which are closed at theirouter ends by means of slide-valvesor .dampers 0'. When the slide-valves rare opened, the heavier external air rushes into the air-channels b and presses the warmer and thinner air through a narrow transverseslot (1, arranged at the rear end of the fire-chamber of the furnace, through which the air is discharged with great force into the fire-chamber. This slot 01 tapers or gradually decreases in area toward the fire-chamber and is arranged in such a mannerabove the grate that the relativelycool air enters at a point as high as possible above the fuel, but directly below the arches a, and thenflows inwardly in the direction of and to the fire-door 0 into the fire-chamber, whereit suddenly expands and is thoroughlyinixed with the combustion-gases coming. from the direction of the fire-doon, In'this way the exhausting or air-suction action of the chimney is placed in front of the furnace, and thereby a high. muzzle velocity through the steam being expanded by the high temperature encountered, so as to give wayto the primary-air entering the ash-pit from below.

40' The continued supply of the secondary air,

2. I eraser slot d that is to say, a high dischhrgeve locity-ihto the fire-chambero'f the cold air taken from the Outside is obtained. Theobje'ctionable heat radiating against the firedoor is also usedcin the same way, asit. also preliminarily heats the air entering 11' through the outside, and it isconduQted to'and fro before it entersthe furnaceata point a, Fig. 14, as high as possible above the grate. By reason of the high temperature in the secondary air entering through the fire-door inasrn'uc motion is i'mpartedto them. The 'nu'mbei'jef the channels 1) depends upon the size of the boiler and from local cond'ition's." .When eaaj coal is used or when clinker is on the gram 1 or when the combustion -is forced, an au'gmented supply of secondary air through the; slot d can be cheated by opening the valve e,

Fig. 4, and admitting the steam through the perforated pipe f, which is arranged behind the sl'otd, so that the steam acts as an injector and takes the at'mospheriefair with it into the fire-chamber.

Thissteam passes through the clinkers, loosens the s'ame', and thereby considerably reduces the production of the same, :such

, would be excessive, and therefore result in a wasteful combustion of the fuel, and hence the secondary air is supplied intermittently at short intervals without the assistance of the fireman. :As soon as the fire door 0, Figs. 1, 3, 4, 6, and 10' to 12, is opened theyoke t, Figs. 3, IO, 12, and 13, which is mounted rigidly on the pintle on which said door turns, turns with it, and through thevmedium of thedi'nks 7c and t" the plug-valve l, Fig. 4, is opened,whereby the hollow sheet-metal reservoirn 'is filled from the water-pipe m, in which said plug-valve turns. After the cylinder 12 is filled it is heavier than the slide-valve 'r, withwhich it is connected by means of suitable."chai'n's or ropes, so that the-said valver is Iift'ed'and the outside air can enter through the borrespondin'g ai'rchannel 1). At the same time by means of the valve 0, arranged below the cylinder 11, a regular discharge of the water from the latter intothe cylinder-p, which is'arranged below it, takes place,whe'reby the said cylinder at is after a certain length of time emptied and is lightened, so that the valve lowers-by reason of-its own weight and overcomes the weight or and raises the cylinder n. From the cyliiider 1 the Water (lis- Also steam may -be 5 admitted through the-perforated pipeh be-j -l 'oit the grate by opening the valves 9, Fig. '4.

charges through 'a. discharge-pipe q. Byadj usting the valve 0 the discharge of the water i from the cylinder'n into the receptacle 1) and the'time for maintaining the valve 1' open may be regulated,'so that the admission and the shutting off of the secondary air is automatically produced."

For the purpose of protecting the walls of the boiler from the direct flame of. the'fire van rear vault -o r arch s, of asuitable fireproof material, is provided; (See Figs.- 1, 2, 8,9, and 14) Referringfto Figs. 10 to 13, it will-be seen.

that the firefdoo'r c is divided by a partition 0' into two chambers.

In Fig. 14 the clean ing-door t in front of the k The air entering at 0" into the first chamber is'guided around the tubes or fines has ahixed thereto a suitable-- water-chamber u], to which wateris supplied through a pipe '0. 7 The said chamber dis.- charges througha pipe w into the receptacle serving to feed the water to the boiler.

be easily removed when this is necessary for 9's I The v pipes 24 and w are so iarranged that they may opening the cleaning-door tto'clean thebo'iler. I I

To facilitate the detachment of the said pipes from the door If, the coupling-pieces of the 'said conduits are constructed in the form of yokes, Figs. 16 and 17 ,-which are pressed airtight to the mouthpieces abn the door 2} by, means of screws m, mounted'on suitable yokes, and suitable washers y. As owing to the high temperature the production of steam i-n'the waterchamber u is possible,' the same, as shown in Fig. 15, is arched on the top, and from the highest point of this arch a steamdischarge pipe zleads-to the ash-pit, By means of this construction not only isi't POS-,

Bible to utilize the cleaning-door t as ordin'a' rily, but a feed-waterheater is-also formed.-

' In Cornish, 'lischbein, and other boilers of similar construction the secondary air is con ducted through the due from the rear by means ofsuitable pipes 13,-of some fireproof v I material, such as I i1'e-clay, silicate of magnesia, 8pc. (See Figs. 6 and 7%) These pipes B are madeo'f such a size that between them and the walls of the dues the fire-gases may just pass, and the latter are pressed against these walls, so that the heating effect is'considerably augmented. 1n furnaces for locomotive and marine boilers, Figs.'6, 8, and 9,

the-secondary air is conducted by tubes D, either one tube, Fig. 6, or several tubes, Figs.- 8 and 9t, whichare fixed in the rear wall of the fire-box and serve instead of stiffeningbolts. These tubes D are by means of pieces f, which are set in, transformed into'tapcring slots. In a locomotive-furnace the mouth of the air-channel b is located at the front above the door of the smoke-chamber, so that the velocity of the engine is used to produce 'compressed air. The air-channel becomes broader and flatter on thebody of the locomotive and fits perfectly thereto, whereby thehigh temperature of the same is utilized for heating the compressed secondary air. In allthese latter cases the self-acting hydraulic appairatus for opening and closing the secondary air-channels is used.

Having thus described my invention, what I claim is-- 1. In a smoke-consuming furnace, the com thefir'e-cham'ber,substantially as set forth.

2. In a smoke-consuming furnace, the combination of the fire-chamber havingasloping arch and, at therear, a tapering broad and narrow slot, arranged approximately in line with the underside of the arch, and means for conducting a supply. of air through said slot to the fire-chamber, alofigand in intimate contact with the under side of; the arch, substantially as set forth. p 3. In a smoke-consuming furnace, the combination of the fire-door having an arm extending therefrom, a water pipe provided with a cock, suitable means for connectingthe latter with, said arm or yoke, a conduitfor supplying air to the fire-chamber, a valve or damper controlling the passage through the conduit, an operating-cord or flexible connection, a pulley over which the same runs, and a movable receptable suspended by said cord, over said pulley, and whereby it is connected with said valve or damper, and into which receptacle the said water -pipe disoharges for lowering it, substantially as set forth.

In testimony whereof I have signed this specification in presence of two subscribing witnesses.
