AXEL H. ENGSTROM, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO GEORGE S. GANDY, OF SAME PLACE.
DEVICE FOR REGENERATENG EXHAUST-STEAM SPECIFICATION forming part of Letters Patent N0. 556,965, dated March 24, 1896.
Application filed November 27, 1895. Serial No. 570,298. (No model.)
To all whom it may concern:
Be it known that I, AXEL II. ENGSTROM, a subject of the King of Sweden and Norway, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Regenerating Exhaust-Steam, of which the following is a specification.
My invention relates to a regenerator for increasing the temperature and pressure of exhaust or low-pressure steam of the type wherein the exhaust is heated, expanded and compressed by live steam and mixed there with to receive the requisite number of heatunits and the pressure required to enable the exhaust to be reutilized, and in such connection it relates particularly to the construction and arrangement of such a regenerator.
The principal objects of my invention are, first, to provide a regenerator of simple construction adapted to efficiently increase the temperature and pressure of exhaust-steam, so that the same may be reutilized; second, to provide a regenerator consisting of a livesteam chamber of expanded form and provided with one or more series of concentric expanding outlet-nozzles and a series of concentric exhaust-steam chambers in communication with the space surrounding the individual nozzles and with each'other; third, to provide in such a regenerator a mixing chamber or chambers consisting of concentric contracted and expanded compartments, the live steam and exhaust being discharged into and mixed together in the contracted compartments and the exhaust compressed in the expanded compartments, and, fourth, to provide in such a regenerator an expanded reser voir or accumulator, into which the expanded compression-compartments discharge, the reservoir having a contracted outlet for the regenerated steam.
My invention consists of a regenerator for increasing the temperature and pressure of exhaust or low-pressure steam, constructed and arranged in substantially the manner hereinafter described and claimed.
The nature and scope of my invention will be more fully understood from the following description taken in connection with the ac companying drawings, forming part hereof, and in which Figure 1 is a longitudinal central section of a regenerator embodying the main features of my invention. Fig. 2 is a cross-sectional view of the same on the line w a; of Fig. 1, and Fig. 3 is a cross-sectional view of the regenerator on the line y y of Fig. 1.
Referring to the drawings, or represents the casing of an expanded or bulbous chamber 1), having an inlet 0 for live steam and a circular partition cl. In the partition cl are screwed or otherwise secured two series of concentric tubes or nozzles e and c, the outlet ends 6 of which are contracted and expanded, as indicated in Fig. 1.
The space within the casing a to the left of the partition 61 is divided into two annular compartments f and f by means of the concentric flanged rings 9 and g,which are sub stantially H shaped in crosssection, as clearly illustrated in Figs. 1 and 3. The compartment f is formed between the ring g and the casing to, and in this compartment are located the pipes or nozzles e. The compartment f is formed between the rings g and g, and within this compartment are located the pipes or nozzles c. The compartments f and f communicate with each other through openings h, formed in the ring g. Surrounding the casing to is an annular box-shaped chamber 2', provided with short studs 0r tubes It, establishing communication between the chamber 6 and compartment f. This chamber z' is also provided with a stud or tube m,connecting the chamber with a pipe on, leading from the exhaust of an engine or other suitable steam apparatus. Live steam entering the chamber Z) through the inlet 0 is expanded and forced through the contracted and expanding nozzles e and 6, while at the same time exhaust-steam from the chamber 71 enters first the chamber f, in which it is partially confined by the flange of the ring 9 and circulates around the pipes or nozzles e, being heated thereby-,and a portion of the heated exhaust enters the chamber f, in which it is partially confined by the flange of the ring g and ring g, circulating between the pipes or nozzles e, by which it is further heated. The compartments f and f open at the left-hand side into concentric annular tapered chambers a and a, the outlets of which chambers are flaring or expanded, as indicated at n and a The live steam as it issues from the nozzles e and e escapes into the chambers n and a, and, creating a vacuum at the point of discharge, sucksthe heated exhaust from the compartments fand f around the flanged edges of the rings 9 and g and forces the same into the chambers n and a, from the contracted throats n and n of which it is dis charged with increased velocity into the flaring chambers a and a in which the mixed exhaust and live steam is compressed. This compression of the steam results in condensation of a portion thereof, the latent heat of said condensation being absorbed by the free steam, by means of which the temperature of the steam is considerably increased.
To the left of the discharge ends of the flaring chambers 02 and n is located a reservoir or accumulator 1), into which the revivified steam escapes and from which it is drawn through the contracted outlet 1" for reutilization in the engine or original steam apparatus.
Having thus described the nature and ob j ects of my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a regenerator of the character described, a live-steam chamber of expanded form, a series of concentric nozzles having contracted and expanded outlets forming the outlet to said live-steam chamber, and a series of concentric exhaust-steam chambers surrounding the concentric nozzles and in communication with a source of exhauststeam and with each other, substantially as and for the purposes described.
2. In a regenerator of the character described, a series of concentric contracted and expanded compartments into which live steam and exhaust-steam are forced, said contracted compartments forming mixing-chambers for the live and exhaust steam and said expanded compartments forming com pression-chambers therefor, substantially as and for the purposes described.
3. In a regenerate]? of the character described, a series of concentric contracted and expanded compartments into which live and exhaust steam are forced, said contracted compartments forming mixing-chambers for the live and exhaust steam and said expanded compartments forming compression-chambers therefor, and a reservoir of expanded form into which the outlets of the expanded compartments discharge, substantially as and for the purposes described.
4:. In a regenerator of the character described, a live-steam chamber of expanded form, a series of concentric nozzles having contracted and expanded outlets forming the outlet to said live-steam chamber, a series of central exhaust-steam chambers surrounding the concentric nozzles and in communication with a source of exhaust-steam and with each other, a series of contracted and expanded compartments into which the live steam from the nozzles an d exhaust-steam from the chambers are forced, said contracted compartments forming mixing-chambers for the live and exhaust steam and said expanded compartments forming compression-chambers therefor, substantially as and for the purposes described.
5. In a regenerator of the character described, a live-steam chamber of expanded form, a series of concentric nozzles having contracted and expanded outlets forming the outlet to said live-steam chamber, a series of central exhaust-steam chambers surroundin the concentric nozzles and in communication with a source of exhaust-steam and with each other, a series of contracted and expanded compartments into which the live steam from the nozzles and exhaust-steam from the chambers are forced, said contracted compartments forming mixing-chambers for the live and exhaust steam and said expanded compartments forming compression-chambers therefor, and a reservoir of expanded form into which the outlets of the expanded compartments discharge, substantially as and for the purposes described.
In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.
AXEL II. ENGSTROM.
