SPECIFICATION forming part of Letters Patent No. 701,921, dated M5310, i902.
, Applioation filed omt'ei 25. 1900. Serial No. 34,262. (No model.)
To aZZ whom it may cortccrnl:
Be it known that we, OHARLEs MUsKER,
ARTHUR MUSKER, and WILLIAM GEORGE HAY, subjects of the Queen of England, and residents of Tue Brook, Liverpool, in the county of Lancaster, England,"have invented certain new and useful Improvements in Con trolling the Generation of Steam, of which the following is a specification.
This invention has reference mainly to the generation of steam by solid fuel, such as coal or coke, for employment in the'propulsion of vehicles on common roads and streets; but it is also applicable forus'e in propelling navigable vessels and other purposes in which it can be advantageously employed. x
It hasmore particularly for its object to provide improvements in connection with same whereby the generation of such steam is regulated or controlled"automatically according to the requirements at all times and under varying. conditions and'also in some cases its temperature. V
According to this invention varying quantities'of steam required at difierent moments are generated by automatically supplying different quantities of air to the fuel of the such air-supply and feedwater supplymeans.
generator by mechanical means-viz., by airforcing apparatus-and also variable quantities of water to the generator, and, further,
the superheat'ing of the steam is regulated or governed automatically, these variable quantities, or quantities and temperatures, being governed or controlled 'by' the pressure of steam in the generator through a suitable governor, which acts directlyor indirectly on The furnace portion, including the ash-pit or hearth, will best closed one, andthe'air will be forced directly from the fan or other blower into it.
This invention is illustrated in the annexed drawings, in which'- Figure 1 is alongitudinal sectional elevation of the improved system 'and combina-,
tion, and Fig. 2 is a plan in cross-section of the furnace portion of the steam-generator.
T Fig. 3 shows a modified arrangement of the apparatus.
Referring to the drawings, and in the first instance to Figs. 1 and 2, a is the portion of the steam-generatorin which "the solid fuel is disposed -and "burn'ed,"forming the firelace or furnace ro er of thef' 'enerator,
tained in the generator is forced to circulate.
The fireplace is a closed one, having a closed bottom a and closed storage feed-hopper a The portion 1) of the generator is a series of concentric coils, there being three injthe case shown, b being the inner coil, b the intermediate coil, and b? the outer coil, and these coils are contained'within a casing b and the space within the inner and intermediary coils at the. outer end is closed or blocked by a plugb c isasmall or auxiliary motor for supplying air for burning the fuel in the fireplace a and for forcing the water through the coils of the steam-generator. This en ine is supplied with steam through a pipe connected with the main steam-supply pipe I), which conveys steam from the steam-generator to the main steam propelling-engine of the'autovehicle or vessel, as the case may be. a e is an air-fan driven by the auxiliary engine c and connected with the bottom of the fireplace a through the air-pipe e and an airinlet branch a on .the casing a. I f is the water-supply pump forsupplying the generator-coils with water, f being the delivery-pipe for conveying the feed-Water to the pipe-coils of the generator, and f is the intake pipe, connecting ,the pump with the supply water tank or reservoir g. (I
h is a pressuregovernor consisting, say, of a piston working in a cylinder, one side of the piston of which is in communication with the pressure of the generator or pipe connected with same, and the other is pressed down by a spring.- In the case shown thiscommunication is effected by a pipe h, connecting the bottom of the cylinder of the governor h with the steam-generator water-feed pipe f while the piston of this governor is connected by a rod 71 with a governor-valve 2' on the steam-supply pipe d of the auxiliary motor 0.
In action the fireplace a would be kept charged with coke or fuel, and air would be supplied to it by the fan 8 in regulated quantities through the instrumentality of the auxiliary engine 0,,which will be kept constantly running, its rate of speed only being varied when the pressure in the steamgenerator pipe system becomes greater than that required. When this happens, this pressure acting on the piston in the governor 7L presses it up and moves the valve t toward its seat in the valve-case, with the result that the supply of steam passing to the engine a through the pipe d is diminished, and consequently the rate of speed of the engine is reduced. This reduction, of course, causes less air to be delivered by the fan 6 into the fireplace a, in which the fuel is burned, and consequently less heat is generated and steam made. (Joncomitantly with this the rate of movement of the water-pumpf, feeding the boiler with water, is reduced in velocity and less water is supplied to it. When the pressure of steam again falls to the normal, the valve 7, is opened by the spring acting on the piston of the gov enor 7t, overcoming the pressure acting against it, whereupon the engine a is given more steam, and the volume of air and water supplied to the furnace or fireplace a and generator is again increased. Thus the greater the quantity of steam used by the motor-engine supplied through the pipe I) the higher would be the velocity of the air-fan c and pump fand the greater volume of air and water delivered-thatis, these quantities synchronize with the rate of consumption of steam taken from the steam-generator.
In the modification shown in Fig. 3 the steam-generator pipes, as well as the furnace portion, are disposed within a single vertical casing a, and the air supplied by the blower e is discharged into a chamber is beneath the bottom plate a, and from this chamber it passes by the pipes a into the furnace a, in which the solid fuel would be disposed and burned. The bottom plate a in this case is provided with an upwardly-projecting cone a and the air from the pipe e is led by a conduit 6 into the upper part of this cone, from whence it passes downward to the lower part of the chamber 70. By this construction the This modification consists in drivingthe fan and pump by the main propelling-engine itself, of which Z represents the crank-shaft, and m the wheel on this shaft for driving the fan e, the plunger of the pump f being driven by an eccentric Z on the shaft Z. In this case the governing of the air is regulated by a slide shutter-valve e on the air-supply conduit e and actuated by the governor it, while the quantity of water is regulated by a valve m on a conduit a, communicating between the supply water-tank g and the delivery-pipe f of the pump f. The action of these parts is that when the pressure in the boiler, and consequently the pipe f, becomes above the normal this pressure acts through the pipe h on the piston of the pressure-governor h and through the lever 0, fulcrumed at 0, moves the slide of the valve 6 in and partially closes the air-conduit e and at the same time opens the valve m and allows the return of water from the deliverypipef of the pump to the water-tank g to take place. When' the steam-pressure is normal or under normal, the spring of the governor 7L acting on its piston presses it down and opens the air-shutter of the valve 6 and closes the return-water-controlling valve m.
What is claimed in respect of the hereindescribed invention is In steam-power machinery, wherein the rate of generation of steam is automatically governed, the combination of a steam-generator, comprising a plurality of annular coils b 12 b a closed furnace (6 adapted to receive and have solid fuel burned within it, in direct connection with the heating-space about said coils; an auxiliary steam-motor c; a pipe (Z connected with the steam-supply pipe of the generator, for supplying steam to the motor 0; controlling-valve t on said pipe (1; a pressure-governor h actuated by the pressure within the steam-generator, connected with and adapted to operate the valve 1;; a pipe 7L connecting said pressure-governor with a suitable pipe connected with the steam-generator and subject to the pressure thereof; an air-supplying fan e and feed-water pump f, both driven by the auxiliary motor a; and conduits e and f connecting the fan with the closed furnace (t, and the pump with the steam-coils of the steam-generator respectively; substantially as herein set forth.
In witness whereof we have hereunto set our hands in presence of two witnesses.
