GEORGE H. GORLISS, OF PROVIDENCE, RHODE ISLAND.
CONDENSER AND FEED-HEATER.
SPECIFICATION forming part of Letters Patent N0. 235,746, dated December 21, 1880.
Application filed June 14, 1880, (No model.)
To all whom it may concern:
Be it known that l, GEORGE HENRY GOR- LISS, a citizen of the United States, residing in Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements relating to Condensers and Feed-Heaters for Steam- Engines, of which the following is a specification.
It is important in the economical working of steam-engines to introduce the feed-water into the boiler at as high a temperature as possible. The water from the condenser is usually at a temperature of 100 to 120 Fahrenheit, (equal to 35 centigrade.) Feeding with such water saves much fuel as compared with feeding the water cold; but in a large class of cases the condensing-water is, by reason of saltness or other quality, not suitable to be fed into the boiler.
My invention is an improvement on the means for heating a separate supply of water.
I construct a condenser of more than usual height, preferably by adding a tall chamber on the top of the ordinary condenser-body. A liberal space is providedin the upper portion, where the cold condensing-water never comes, and in this space I arrange a series of pipes, with provisions for expansion and contraction, due to variations of temperature. The fresh water for feeding the boiler is caused to circulate through these pipes, and can thus attain a temperature considerablyabove that of the hot salt-water pumped out from the condenser.
The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.
Figure l is a vertical section of the feed- ]leater, partly in elevation. Fig. 2 is a correspondin g section at right angles to that in Fig. 1. Fig. 2 also shows an outline of the cylinder from which the steam is received.
Similar letters of reference indicate like parts in both the figures.
Referring to the figures, E is the main body of the condenser, and Eis atall chamberbolted on the top thereof, with stuffing-boxes in the upper end, through which are passed water-pipes e. The pipes are madein several pieces and united, so as to cause the water to traverse up and down several times in passing from the entrance to the exit. The steam is received alternately through the two nozzles (t' a of the cylinder A, and fills the entire chamber with the weak steam, which bathes the feed-pipes e, and imparts its heat thereto without exposing the feed-pipes to any contact with the cold injection-water. The pipes care suspended on -cross-pieces E at the upper end, and are stead- 6o ied by corresponding or smaller cross-pieces E below. It is important that the crosspieces E be so arranged asto efficiently steady the pipes and prevent their being moved by the blasts of exhaust-steam, which are received intermittently, while they at the same time allow the pipes e to freely move up and down to the small extent required to accommodate the expansions and contractions with variations of temperature. The stuffing-boxes 0 allow the pipe to move in and out with sufficient freedom to avoid mischief.
The chamber E performs the double functions, first, of a liberal passage for the easy flow of the steam from the receiving ports or nozzles a a to the main body E of the condenser, where it is exposed to contact with cold water and condensed in the long-approved manner, and, second, as a heatingchamber for the feed-water circulating in the pipes e, where it is freely exposed to the heat of the steam flowing past it to the condenser, and is not touched by the cold water injected.
I have shown two sets of pipes, e. The invention may be made to succeed with only one set, or more than two sets may be employed,if preferred. The chamber E is adapted for ready separation, to allow access to the pipes for repairing or exchanging, when required. o
Modifications may be madein the forms and proportions. I can make the pipes e, a con tinuous pipe of iron, copper, or other material, either extending several times np and down, or extending transversely or coiled, 5 or variously convoluted. I esteem it important to provide that the steam may circulate freely through the spaces and obtain access to the exterior of all parts of the pipe 6, that the passage may be liberal for the free descent of the steam among the pipes, and that the pipe or pipes be allowed to expand and con- 2. In a steam-engine, the cylinder A, connections a a condenser E E, feed-pipe e, and snpportslil E for the latter, arranged to serve 1 as and for the purposes herein specified.
In testimony whereof I have hereunto set my hand, at Providence, Rhode Island, this tract freely, but confined against any rattling I motion when subjected to the violent impact of the exhaust-steam. I claim as my invention 1. The condenserdescribed, formed in two parts, E E, the lower part, E, receiving the condensing-water to condense the steam, and 9th day of J nne, 1880, in the presence of two the upper part, E, receiving the first rush of subscribing witnesses. the steam, in combination with a device, 0, exposing a large surface in the upper part, E, properly connected for the passage of feedwater, as herein specified.
