' gii fiifi i CHARLESYE. CHAPMAN, PORT EDWARD, NEW YORK, ASiiIGNOR OF ONE-HALF TO I JOSEPH GOOIDFELLOW, 0F FORT EDVTABD, NE W YQEK.
SUPERHEATER.
To all whomz't ma concern:
Be it known that 1, Cinemas EICHAP MAN, citizen of the United States, residing at Fort Edward, in the co'unty of Washington and State of New York, have invented certain new and useful Improvements in Superheaters, of which the following is a specification.
This invention relatesto a superheater adapted for attachment "to internal combustion engines for the purpose of utilizing the exhaust heatfrom the engine for heating and mixing air and steam and supplying the sameto .the,.carbureted air forming the explosive mixture used in an internal combustion engine.
In detail, the invention consists of a unit superheater feeding to the air intalre of the carbureter or other fuel mixture 0 forming device a thorough mixture of superheated air and steam resulting from passing air and steam through separate tubular compartments around which exhaust gases from the engine are circulated,
such compartments each containing a group of flues or tubes.
A further feature of the invention is the provision of means for keeping separate the air and steam during passage through the superheater and then thoroughly mixing the superheated products after passage through the superheater tubes.
In the drawings:
Figure 1 is a vertical longitudinal sec tion through the superheater,
Figure 2 is a transverse section in a vertical plane on the line 2-2 of Figure 1.
The invention, as herein shown, comprises a rectangular shell 1 flanged at each end as indicated at 2 to receive tube sheets 4 and 5 which are perforated for mounting the superheater tubes 6. The shell 1, next to the sheet a, is perforated as shown at 7 to permit the escape of ex haust gases and nipples 7 and 8 admit exhaust gases direct from the exhaust pipe and from a secondary superheater, respectively. One side of the superheater shell 1 is provided with tracks 9 in which the side 10 slides to provide for removing said side for cleaning the superheater tubes 6 of soot formation.
On the inlet end and abutting the sheet a is a rectangular end unit 11 closed by a cover plate 12 to form a receiving chamber,
the unit being clamped between the plate and said sheet by bolts 13 extending through the plate, sheet and adjacent flange 2. The cover plate 12 has openings 1% and 15 for steam and air respectively and which are separated from each other by a partition 16 extending between the tube sheet f and cover plate dividing the chamber into compartments.
A tthe opposite end of the superheater, a similar rectangular end unit 17 and cover plate 18 provide a mixing chamberand aresecu'red by bolts 19 extending through the cover plate, tube sheet and adjacent flange 2. The cover plate 18 has a nipple 20 which may be connected to the air intake of a carbureter while, within the mixmg chamber, said plate carries supports 21 mounting a conical deflector 22 disposed opposite the nipple to overlie the outlet opening of the chamber.
The air and steam enter separately as indicated at 14; and 15 and pass through the superheater tubes 6 which, by reason of the partition 16, are divided into two groups. The exhaust gases entering at 7 and 8 pass around the superheater tubes thoroughly superheating the air and steam and are emitted through the openings The air and "steam leave the superheater tubes at the tube sheet 5 and enter the 11111; ing chamber 17 but are prevented from directly passing out by reason of the baffle 22 against which they impinge, the flow being obstructed sufficiently to permit the air and steam to mingle in a homogeneous mixture. The mixture thus formed passes out as indicated by the arrows, beneath the deflector 22 and enters the air intake passage of the carbureter. It will be seen from the foregoing, that the superheater herein described, provides a means of supplying a highly heated mix- 'ture of comingled air and steam to the carbureter of an internal combustion engine and such mixture is particularly adapted for use in apparatus for burning coal oil and the like in motor vehicles.
Having thus described the invembion, what is claimed as new is:
1. A superheater for air and steam cone prising separate groups of superheater tubes. means for feeding steam through one group, means for feeding air through another group, and a mixing chamber common to the groups for receiving the discharge therefrom to comingle Within the chamber.
2. A superheater for air and steam comprising separate groups of superheater tubes, means for feeding steam through one group, means for feeding air through an other group, a mixing chamber common to the groups for receiving the discharge therefrom to comingle Within the chamber, and a baflie Within the chamber for diverting the flow of both air and steam.
3. A superheater for air and steam comprising separate groups of superheater tubes, means for feeding steam through one group, means for feeding air through another group, a mixing chamber common to the groups for receiving the discharge therefrom to comingle Within the chamber, the chamber being provided with an outlet,
and a baffle Within the chamber overlying said outlet.
4:. A superheater for air and steam oomprising separate groups of superheater tubes, chambers at opposite ends of the tubes, and means dividing one of said chambers into a steam com artment for feeding steam to one group 0 tubes and an air compartment for feeding air to another group of tubes, the other of said chambers being common ,to the tubes for receiving the discharge therefrom to mingle within such chamber.
5. A superhea-ter for air and steam comprising separate groups of superheater tubes, chambers at opposite ends of the tubes, means dividing one of said chambers into a steam compartment for feeding steam to onegroup of tubes and an air compartment for feeding air to another group of tubes, the other of said chambers being common to the tubes for recelving the discharge therefrom to mingle Within such chamber, the latter chamber being provided with an outlet, and a bacflie mounted in juxtaposition .to said outlet. In testimony whereof I aflix my signature.
