STEAM-E QUALIZER.

Specification of Letters Patent. Application filed September 30,

To all who) Qit may concern:

Be it known that citizen of the United cago, 1n the county I, HENRY H. VVArr, a

States, residing at Chiof Cook and State of .llliiiois, have invented a certain new and useful Improvement i 11 Steam-Equalizers, of

which the following is a full, clear, concise,

and exact description. This invention relates gines, absorb the equaline the pressure tinuous supply of stea constant pressure. su pressure turbines. an improved appai'at will received from the e back-pressure.

Patented Oct. 26, 1909. 1908. Serial at. 455,564.

The steam is preferably directed into repeated contact with the surface of the fluid by means of a helical steam chamber through which the steam flows in such a manner that at each convolution it passes across the tluid surface, and finally returns through a central pipe, around the outside of which said helical chamber is formed. A similar helical chamber; is preferably provided for the water or other fluid, so that such fluid-setin motion by the impact of the steam follows a helical path, at each convolution of which it is exposed to the steam. The heated fluid is thus caused to mingle thoroughly with the portions which are cooler, so that fresh surfaces are continually being exposed, and the heat thus ctliciently absorbed.

I will explain my invention in detail and describe further features thereof by reference t0 the particular embodiment shown in the accon'ipanying tll'iH 'ing, which is illustrative. of the principles involved.

Figure l is a sectional elevation of my lll'lPl'OVOtl steam regenerator; Fig. 2 is a sectional plan view thereof; and Fig. 3 is a crosssection on line 33 of Fig. l.

The same reference characters indicate the same parts wherever shown.

In the form ofeqiializer shown, the container d is a horizontal hollow cylinder having pipes a and (3 extending longitudinally therethrough, and plates 7, 7, forming a double helix throughout the container, said plates extending from the outer surfaces of said pipes to the inner walls of the container. The container will be filled with water up to approximately the level indieated, which will not ordinarily rise above the under surface of the upper pipe 5. The surface of the water forms one wall of a helical steam chamber formed by the plates 7, 7, about the upper pipe 5, said helical chamber thus forming constricted passages constituting, in effect, nozzles for directing a: substantially free and unimpeded current of steam into ent aining contact with the surface of the water. At one end, said steam chamber-is in COllllIlHIllCtLtlOll with a source of exhaust steam 8, and at the otherend it,

communicates with an inlet the interior of the pipe 5.

end of said pipe 5 which the steam is Withdrawn to be utilized in a low-pressure turbine or otherwise. As shown, the outlet pipe 9 leads into a trap 9 leading into At the opposite there is an outlet-9 from lows: Exhaust steam a mitted from 14- adapted to receive and collect any entrained water, and a pipe leads from said trap to the turbine or other device which is to utilize the steam. 'Bafile plates 16, 16, are preferably provided. within the pipe 5 to reduce the speed of the steam current and assist in equalizing the pressure thereof. The plates 7 also form a helical chamber for the fluid surrounding the lower pipe 6. Said pipe 6 has an inlet opening 11 at one end thereof, -and an outlet'opening 12 at the other end, said openings being in communication with the helical water chamber, so that the water after flowing through the helical convolutions in one direction will be returned through the pipe in the opposite direction.

Suitable means will be provided for preventing the fluid in the container from rising above a given level. As shown, an overl'low pipe 13 leads from the water chamber to the chamber 1-1 of the trap, which is provided with a float-valve 15 adapted to open when the water rises above a predetermined point. The regenerated steam is conducted from the chamber 1% through the outlet pipe 10.

The equalizer may also be provided with an automatic escape-valve for steam, adapted to open if the steam pressure should for any reason rise above a predetermined value.

I preferably provide deflecting plates within the container, to assist in directing the steam and water currents. Theplates 17, 17, assist in. directing the surface water downward so that-it may pass under the pipe 6 and rise again in the next compartment or convolution of its helical passage. The steam-deflecting plates 18 are preferably sheets of metal fastened at one edge to the side of the upper or steam pipe 5, and conforming in shape to the pitch of the convolutions of the helical steam chamber. The free edges of said plates are adj ustably supported so that the lowersurfaces thereof may be brought nearer to or farther from the surface of the water in the corresponding compartment; whereby the impact of the ste n upon the water, and the amount of sin ice water to be disg; eed in each compa' cut may be regulated.

i coil spring at the inner end of the plate 18 may be employed in order to maintain the outer or free end of said plate in close engagement with steam-pipe I The operation of the a paratus is as folthe pipe 8 is carried downward around the side of the pipe 5, in the first compartment, and is blown through the narrow horizontal space between the surface of the plate 18 and the surface of the water. After passing through this openin the steam current is conducted in a spiral path around the pipe 5 into the next compartment, where it agaln blows through the opening next to the surface of the water, and so continues in its travel through the helical chamber, being repeatedly directed into impact with the water in the successive compartments, until, in the last compartment, it passes through opening 9 into the interior of the pipe 5. Its passage through said pipe is retarded by the battle plates 16. The entraining contact of the steam current against the surface of the water in each compartment draws the Water laterally across the container so that it tends to circulate around the lower pipe 6. Such circulation is assisted by the directing plates 17, and the water with which the steam con-- downwardly into the colder portions of the body fluid, which is thus caused to absorb the heat. The violent surging of the steam received is retarded and the pressure thereof equalized, so that the delivery from the pipe 9 will be approximately constant in pressure.

It will be observed that the passage of steam longitudinally through the vessel by way f the helical steam chamber is in a direction opposite to the longitudinal flow of water through its helical chamber. One object of this arrangement is to make the head produced by the friction of the steam on the water partially compensate for the difference in head caused by the drop in pressure of the steam as it passes through the successive compartments. If the arrangement were such that the water and steam traveled longitudinally in the same direction, instead of in opposite directions, there would be a tendency for the water to pile up still higher in the successive compartments. With the arrangement as shown, the flow of water in its helical chamber is toward the lefthand end of the container, while the helical flow of the steam is toward the right hand end; so that the tendency of the water to pile up at the left hand end of the container is opposed by the effect of the slightly higher steam pressure in the first steam compartments.
