FRANK O. ROMKEY, OF TOLEDO, OHIO.
STEAM-GENERATOR.
j SPECIFICATION forming part of Letters Patent N o. 467,835, dated January 26, 1892.
Application filed March 27,1891. Serial No. 387,657. (No model.)
To all whom it may concern:
Be it known that l, FRANK O. ROMKEY, of Toledo, in the county of Lucas and State of Ohio, have invented a new and Improved Steam-Generator, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved steam-generator which is simple and durable in construction and in which the water in jets is evaporated to mix with the products of combustion arising from the burning fuel in a furnace.
rlhe invention consists, principally, in a gas-producing furnace, one or more evaporators connected with the combustion-chamber of the said furnace, and a water-jacket held on the said furnace and discharging into the said evaporators.
The invention also consists of cert-ain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line :c in Fig. l. Fig. 3 is a sectional plan view of the improvement on the line y y in Fig. l, showing the revolving' grate. Fig. 4 is a sectional plan view of one of the evaporators on the line .a a in Fig. l. Fig. 5 is a like view of the same on the line w w in Fig. l, and Fig. 6 is a sectional side elevation of one of the disks of the evaporators.
The improved steam-generator is provided with a gas-producing furnace A, containing a fire-box B, in which is held fuel O in an incandescent state, said fuel, which is preferably coal, resting on a revolving grate D, below which is arranged the ashpit E, closed air-tight, so that air and water can be introduced into the same under pressure, as hercinafter more fully described.
The grate D is mounted at its center on a suitable pivot, around which the grate revolves, and the under side of the grate is formed with a gear-Wheel D', in mesh with a pinion D2, secured on a radially-extending shaft D3, passing through the shell of the furnace to the outside and carrying ou its outer end a crank-arm D4 for conveniently revolving the said grate D, so as to agita-te and regulate the burning fuel.
The fire-box B is surrounded by a waterjacket F, provided with an inlet-pipe G, havinga valve G', the said jacket being also provided near its upper end with an outlet-pipe G2, passing through or discharging into the outlet-flue B of the combustion-chamber of the fire-box B. The Water in the jacket F is heated by the heat generated in the fire-box B. The jacket F contains a circular pipe Il, fitted closely around the fire-box B and provided with inwardly-extending short pipes or nipples Il', which pass or extend into the combustion-chamber of the fire-box B-that is, a short distance above the burning fuelas is plainly shown in Fig. l.
The pipe Il is connected with a pipe 112, leading to the compressing-cylinder of an aircompressor J of any approved construction. Then the air-compressor is set in motion, the compressed air passes through the pipe H2 into the pipe Il, and from the latter through the nipples H into the combustion-chamber of the lire-box B, so as to mix with the gases arising from the burning fuel. In'order to regulate the amount of air passing through the pipe Il the pipe H2 is provided with a valve H3. From the pipe ll?, near the valve H3, leads a branch pipe K, which discharges into the air-tight ash-pit E, the said pipe being provided with a valve K for regulating the amount of air taken from the pipe H2. Into the branch pipe K, below the valve K', opens a small Water-pipe L, having a valve L, and connected with a globe or dome L2, arranged on top of the Water-jacket F, so that steam or water from the water-jacket can pass to the dome L2, then through the pipe L, past the valve L', into the branch pipe K, to mix with the air therein, the mixture being dis` charged into the ash -pit E, from which it passes through the grate D and through the glowing coal O to produce carbonio oxide, which is mixed with the compressed air from the nipples Il', whereby complete combustion of the burning fuel is obtained, the oxygen being combined with the carbon and the hy- IOO drogen of the steam being setfree to be burned in the combustion-chamber. l
From the upper end of the fire-box l5 leads an outlet-pipe B', connected with the upper end of an evaporator N,into which discharges the jacket outlet-pipe G2 and which contains sets of alternating disks N and N2, arranged horizontally therein. Each disk N is arranged centrally, so as to form at. its outer edge an annular space with the inner shell of the evaporator, the next disk N2 being secured to the shell of the evaporator, and having a central opening N3 by which the mix- Y ture passes Yupon the next following disk N',
to be spread by the latter to the outer edge and to pass through the annular space down to the next following disk N2, and so on until the mixture iinally passes into a pipe O, connecting the lower end of the evaporator N with the lower end of a second evaporator P, also provided with sets of disks P and P2, similar in construction to the disks N and N2 in the evaporator N. The upper end of the evaporator P is provided with an outlet-pipe P3, through which the motive power is carried to the machinery to be driven. From the upper end of the evaporator P also leads a small pipe Q, provided with a valve Q, and discharging into the cylinder of the compressor J, so as to actuate the latter. pipe Q is further provided with an automaticallyoperating valve Q2, on the stem of which is secured a crank-arm Q2, connected by a link Q4 with the lever R of av diaphragm R. connected with the evaporator P, so that the mixture from the evaporator presses on the diaphragm, whereby the lever R of j the latter controls the movement of the valve rator N.
Q2. The lever R is also connected by a link R2 with an arm G5 on the stem of the valve G controlling the inlet of the water to the water-jacket F. From the upper end of the evaporator P also leads a short pipe S, provided with a valve S and connecting` with a pipe T, which is connected with a water-supply and discharges into the jacket dischargepipe G2, leading to the upper end of the evapo- The pipe T is provided with a valve T. The pipe G2 is provided with a branch pipe G2, connected with the evaporator P and containing a valve G4, as is plainly shown in Fig. l.
The top of the furnace A is provided with a removable cover U, through which fuel is introduced into the fire-box B whenever necessary. A similar cover is arranged on the ash-pit E, so that the ashes can be removed at certain intervals at a time when the pressure withinthe ash-pit and the combustionchamber is zero.
The operation is as follows: The air-compressor J forces air under pressure into the re-box B above the burning fuel, and also air under pressure is forced into the air-tight ash-pit E, the lair passing upward through the burning fuel with the water or steam entering the pipe K by the pipe L. Complete The combustion is thus obtained in the fire-box B, the gas passing from the latter through the outlet-pipel into the evaporator N, in which the heated Water from the Water-j acket is discharged in a continuous stream and is completely evaporated by the heated gases, thus forming steam. Complete evaporation, if necessary, takes place by forcing the mixture through the second evaporator P, so that the motive power in the upper end of the evaporator P is in a very dry state and can be readily utilized for various purposes. The amount of compressed air passing into the furnace A is regulated by the valves H3 and K', and the amount of Water or steam permitted to pass into the pipe K is regulated by the valve L', so that a perfect mixture for the complete combustion is under the control of the operator. The water-supply to the water-jacket F is automatically regulated from the diaphragm R, and in a similar manner the supply to the air-compressor J is regulated from the same diaphragm,as the latter controls the valves G and Q2. The temperature of the motive power in the upper end of the evaporator P is measured by a suitable thermometer V. (Shown in Fig. l.)
The ash-pit E is preferably made sufficiently large so that the process can be carried on uninterruptedly for several hours before it will'be necessary to open the ash-pit for the removal of the ashes-at a time, however, when the pressure in the said ash-pit has been reduced to zero. In a like manner additional fuel is introduced into the fire-box B through the coverU after the pressure in the upper-end of the fire-box has likewise been reduced to Zero.
In case it is desi red to clean the evaporators N and P of sediment or other impurities, a pipe O is provided in the connecting-pipe O containing a valve O2. By 'opening the latter the impurities are washed out through the pipe O. The fuel C in the furnaceA can be regulated at any time by the operator turning the handle D4, so as to impart arevolving motion to the grate D.
The disks NW and N2, P, and P2 are secured in their evaporators in any suitable manner, preferably, however, by forming each disk on its underside with posts resting on the next following disk. (See detail View, Fig. 6.)
It is understood that the heated water from the water-jacket F passes into the pipe G2, and through the lower end of the pipe T into the upper end of the evaporator N, whereby the products of combustion from the tire-box Bthoroughly heat the disks N and N2, and thereby cause a rapid evaporation of the hot water, the steam thus produced mixing with the said products of combustion.
In case the water from the jacket F is not all evaporated or turned into steam at the time it reaches the lower end of the evaporator P, then the valve G4 is wholly or partly opened to permit the surplus water to pass IOO IIO
from the jacket F to the evaporator P directly, to be changed therein into steam on the disks P and P2, heated by the products of combustion passing upward in the said evaporator and coming from the evaporator N.
