Specification of Letters Patent.
Patented Feb. 23, 1915..
Application filed June 19, 1913. Serial No. 774,613.
To all whom it may concern:
Be it known that I, EDUARD PIELooK, a
subject of the Emperor of Germany, and resident at 14 Landshuterstrasse, Berlin, Germany, have invented certain new and useful Improvements Relating to Steam- Generators.
This invention relates to an improvement or modification of a steam-generator for a locomotive boiler or combined firebox and multitubular boiler, in which means are provided for uniformly distributing the air stimulating combustion, continuously mixing the heating gases, preventing smoke, the deposit of ashes in the heating or flame tubes and the ejection of incandescent fuel from the chimney.
According to the present modification, the air for the combustion is heated in a chamber, separated by a stepwise depending wall from the smoke chamber intermediate the firebox and the horizontal multitubular boiler, from which the smoke is conducted through passages and distributed beneath the fire-grate. The combustion gases strike against said depending wall, are heated to white heat, and when deprived of floating ashes they pass in streams through flame tubes in which they are repeatedly contracted and caused to whirl in the usual manner.
The modified arrangement is shown in the accompanying drawings, in which Figure 1, is a longitudinal section of the steam generator. Fig. 2, is a cross-section. Fig. 3, is a cross-section through the firegrate and ash-pit. Fig. 4, is a horizontal section taken on the line CD of Fig. 3.
Between the upright firebox 1 and the horizontal multitubular boiler 2 is the known intermediate chamber 3 which does not serve as a steam-generator and in which is contained a wall 4: of refractory material which separates the inner space from the outer walls of said chamber and leaves channels or passages 5 at both sides for the air supply to the grate. In the chamber 3 surrounded by the walls 4 there is a depending wall 6 in the form of an arch composed of steps 7 facing toward the firebox, said arch being composed of refractory material rendered incandescent by the flames from the fire. The lower part of the chamber 3 receives the ashes separated from the fire gases in striking the arch as hereinafter explained. The air-supply for the grate enters through a closable aperture 9 and passes along the channels 5 (Fig. 2) and through a door 10 into channels 11 and 12 built in the ash-pit and so beneath the grate 13 (Figs. 1 and 3), thus causing a better combustion than is the case with ordinary fire-grates.
The ash-pit is separately shown in Figs. 3 and 4: because of its great importance, it being entirely closed during working, cinders being prevented from falling out and air being supplied from the channels 12 to the sides and the middle of the grate. It is advantageous to make the outlets widerat the ends opposite the inlets so as to insure better distribution of the air, and if desired a greater number of distributing channels may be provided. The air current can be regulated by means of the door 10 from the exterior. For the supply of air above the grate, especially when coal containing much carbureted hydrogen is used, there are provided distributing nozzles 14: along the walls of the firebox, said nozzles controlled by a slide extending along the entire wall of the firebox. Having thus provided the most advantageous arrangements for the combustion, the fire-gases in leaving the firebox 15 have to pass through an opening 16 calculated to give the smallest cross-section for a maximum velocity of the gases so that the latter strike with great intensity against the arch 7. This violent impact with the steps of the arch causes the gases to mix intimately and at the same time to separate out the solids carried with the gases, the solids falling into the collecting space 8 of the chamber 3. With this arrangement complete combustion with less smoke is obtained, while emission of burning fuel from the chimney and the choking by ashes of the heating or flame tubes are practically avoided. The air entering the opening 9 becomes heated in the space 18 by the upper brickwork and along the channels 5 in the side wall 4: the heating efiect being increased by iron plates arranged between projecting parts 19 (Fig. 2), while at the same time the air cools the walls and so causes same to last longer than they would otherwise. The bricks for lining the walls of the intermediate chamber are seatedin suitable openings 20 formed in the plate 22 which carries the refractory material see Figs. 1 and 2. It is advantageous to make one or more of the rows of projecting bricks more protruding than the others so that such protruding bricks 23 may cause whirls in the air current and thereby facilitate the heating 0]": the same.
I claim 1. In a steam generator of the fire tube type the combination with a fire box and a fire tube boiler lying in spaced relation thereto, of a chamber between said firetubes and said fire box, a second chamber surrounding the first named chamber, means for supplying outside air to the last named chamber and connections leading from the last named chamber to a point beneath the grate.
2. In a steam generator of the fire tube type the combination with a fire box and a fire tube boiler lying in spaced relation thereto, of a chamber between said fire tube boiler and said fire box, a second chamber surrounding the first named chamber, means for supplying outside air to the-last named chamber and connections leading from the last chamber to a point beneath the grate and a depending bafiie Wall extending downwardly from the top of the first named chamber and terminating short of the bottom of said chamber.
3. In a steam generator or the fire tube type the combination With a fire box and a fire tube boiler lying in spaced relation thereto, of a chamber between said fire tube boiler and said fire box, a second chamber last chamber to a point beneath the grate and a depending baifie wall extending downwardly from the top of the first named chamber and terminating short of the bottom of said chamber, stepped face.
t. In a steam generator of the fire tube type the combination with a fire box and a horizontal fire tube boiler lying in spaced relation thereto, of a chamber between said fire tubes and said fire box having a depending baflle wall, a second chamber surrounding the first named chamber, means for admitting air at the top of said second chamher, a compartment beneath the ash pit of said wall having a the fire box with which said second ChitlTlr ber has communication, and discharge conduits leading upwardly from said compartment and arranged to discharge heated air beneath the grate of the fire box.
In testimony whereof I have set hereuntfl my hand in presence of two witnesses.
