MEANS FOR UTlLlZING COMPRESSED AIR FOR THE PRODUCTION OF MECHANICAL POWER.
SPECIFICATION forming part of Letters Patent No. 456,594, dated July-28, 1891.
Application filed April 9, 1889. Serial No. 306,619. (No model.) Patented in France November 8, 1888, No. 193,980; in Belgium November 14, 1888,1lo. 83,946, and in England November 22, 1888, No. 17,006.
To @ZZ whom it may concern,.-
Beit known that l, VICTOR POPP, of the city of Paris, France, have invented Improve ments in the Method or Means of Utilizing Compressed Air for the Production of Mechanical Power, (for which I have obtained Letters Patent in France for fifteen years, dated November 8, 1888, No. 193,080; in Belgium for fifteen years, dated November let, 1888, No. 83,946, and in England for fourteen years, dated November 22, 1888, No. 17,006,) of which the following is a full, clear, and eX- act description.
It is well known that when compressed air is used for the production of motive poweras, forinstance,in the system associated with niy name and patented June 25, 188i), No. 405,971-it is very advantageous for the air to be superheated with the object of obtaining a greater useful. effect.
The present invention has for its object to further increase this effect, the method involved in this invention being claimed in my application, Serial No. 349,380, tiled April 24, 1890, and the apparatus for carrying the method into effect being claimed herein.
According to my invention distilled water or other suitable liquid, previously heated, is injected into the pipe or conduit which supplies the highly-heated compressed air to the motor. This injection is effected under pressure at or before the moment of consumption of the compressed air in the form of atomized liquid or spray. The compressed airis by this means saturated with moisture, which is transformed into superheated steam by the heat contained in the air. A higher pressure is thereby obtained, which allows of a more favorable rate of expansion in the motor. The moisture present in the air also serves as avaluable lubricant for the parts of the motor.
One arrangement which l may employ for carrying this invention into practice is shown byway of example in the annexed sheet of illustrative drawings. The compressed air is supplied from a suitable source (not shown) by a pipe a under a constant pressure, which is maintained by means of an automatic pressure-regulator. (Not shown.) The compressed air passes through a valve b, which, since there is always maintained a constant pressurein the pipe a, allows only a constant but somewhat lower pressure to reach the motor, thisva'lve opening or closing according as the motor requires moreor less speed or power. The water or other liquid to be injected is contained in a reservoir d, provided with a gage-glass e or other suitable device for indi-V cating the level of the liquid. The reservoir is hermetically closed, and its contents are subjected to the same constant pressure as that in the pipe a by means of a connectingpipe f, which opens into the pipe a in front of the valve Y).
The reservoir (Z is provided with a screwplug, which can be replaced bya union forming the end of the delivery-pipe of a small pump, hereinafter referred to. This reservoir d is connected by a pipe m to a heater which serves to heat the compressed ai r. This heater receives the compressed air before its admission to the motor. The air passes bya pipe l into a Vseries of passages formed by baffle-plates which compel the air to pass round the furnace while iiowing alternately upward and downward in the heating device.
The heated air passes out bya pipe 3,Which, conveys it to the motor. The heat radiated,
tween this casing 4 and the outer casing 5 of the heater is arranged a coil of piping b, dimensioned according to the most suitable te1nperature to be given to the injection-liquid. The Water from the reservoir d is forced into the coil Z) by reason of the difference between the pressure existing in the pipe ain front of the valve Z), which is a constant pressure, and the pressure in the pipe l behind that valve, which is a variable pressure, varying according to the working of the motor. The liquid is driven into the heating-coil (i with a force proportionate to the diiference in the pressurcs. The liquid, being thus heated in the coil, is forced by the action of this difference in the pressures out through a pipe g into a receiver t', provided with means for rendering visible the volume of discharge. From this IOO receiver the heated liquid passes into an atomizing or sprayingpipe or device j, which opens into the pipe l, supplying the compressed air to the heater. The atomized liquidis sucked or drawn along at 7c by the current of compressed air, which is thereby saturated with moisture before entering the heater. By the action of the high temperature in the heater the liquid mixed with the air is changed into steam, which causes an increase of pressure of the motive fluid, while diminishing the consumption. The difference in pressure which forces the water into the coil is variable, since one of the pressures is itself variable, while the other is constant. The amount of water injected and drawn along by the compressed air will therefore also be variable. The proportionate discharge of this liquid is effected in an automatic manner; but it may also be effected mechanically by means of the following arrangement, which regulates the supply of liquid according to the requirements and proportionally to the consumption of compressed air by the motor. A lever n, connected to the valve h, carries the counter-weight 0, andis extended to p. It is here jointed to a rod g, which is jointed to the end of a lever r, fixed on the plug of the cock s, inserted in the pipe m, forming the communication between the reservoir d and the heater. Vhen the valve b rises in order to allow a greater quantity of compressed air to pass, the lever r is operated to open the plug of the cock s, so as vto allorir a greater quantity of water to pass into the coil. A pressure-gage may be placed on the pipe a in front of the valve Z9 to indicate the constant pressure. A pressure-gage and a thermometer may be placed on the pipe l behind the valve b to indicate the pressure and the temperature of the compressed air min gled with atomized liquid. The reservoir d is also provided with a pressure-gage which should always agree with that on the pipe a..
A thermometer may be placed on the pipe 3, which supplies the compressed air mixed with steam to the motor, in order to indicate the temperature of the mixture.
ln order that the water in the reservoir CZ may be renewed Without interference with the working of the apparatus, the exhaustpipe of the motor may be immersed in a sump or other reservoir of Water. The steam mixed with the compressed air after its action on the motor becomes condensed in this reservoir, and a small pump, hereinbefore referred to, worked by hand or by the motor itself, returns to the reservoir d the water which has been injected. It is thus practically always the same liquid which is injected, with the addition of aquantity of fresh liquid to make up for loss by leakage and evaporation.
By the means. hereinbefore Adescribed the useful effect of the mo-tive force of the compressed air employed may be increased al most without extra cost.
In place of water, any other suitable liquid or substance may be employed for the purpose of injection which shall be capable of producing by admixture with the compressed air a fluid Whose motive force will be added to that of the said compressed air.
I claiml l. The combination, with pipe a, leading from a distant source of compressed -air transmission, of a local receiving` apparatus for motive power, consisting of a reservoir of liquid maintained under pressure, a heater connected to said reservoir and receiving the liquid'therefrorn, and a connection from the said heater to the pipe a, by means of which the liquid after being heated is mingled with the compressed air in said pipe and is conducted therein to a motor operated by the combined pressure of the air and liquid vapor.
