ALEXANDER E. J. WHITNEY, OF LEADVILLE, COLORADO.
FEED-WATER HEATER.
SPECIFICATION forming part of Letters Patent No. 358,177, dated February 22, 1887.
- Application filed August 19, 1886. Serial No. 211,278.
To all whom it may concern:
Be it known that I, ALEXANDER E. J WHIT- NEY, of Leadville, in the county of Lake and State of Colorado, have invented a new and Improved Feed-Tater Heater, of which the followingis afull, clear, and exact description.
The object of my invention is to provide a new and improved feed-water heater for boilers which thoroughly beats and purifies the water before it enters the boiler.
The invention consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
[5 Referenceis to be had to the accompanying bf my invention attached to a stationary boiler.
Fig. 2 is a vertical cross-section of the same on the line at m of Fig. 1. Fig. 3 is a side elevation of my improvement attached to a 1000- motive-boiler, and Fig. 4 is an end View of the same.
The boiler A, of any approved construction, isprovided with the usual steam-dome, B, from which leads a pipe, 0, into the tank D, supported in any suitable manner above the waterlevel of the boiler A. The pipe-G, before entering the tank D, is provided with a valve, E, and is formed into a coil in the tank D, and its end opens into the latter at the rear near the top. A pipe, F, opens into the tank D a 5 few inches above its bottom and leads downward, its lower end being connected with the water-compartment of the boiler, and said pipe F being provided with a valve, G.
The water-supply pipe H connects with the tank D, and is provided with avalve, I, and a blow-out valve, J, is secured to the bottom of the tank D. The tankD is also provided with a series of tubes, K, arranged longitudinally, and connected at one end with the exhaustpipe Lof the engine used in connection with the boiler A.
The operation is as follows: The tank D is filled with water through the water-supply pipe'H when the valves E, G, andJ are closed,
and after the tank is filled, or nearly so, the
valve I is closed and the valve E is opened, whereby the steam in the boiler Apasses from (No model.)
the dome B into the water-tank D by means of the pipe 0, and heats the water thoroughly on its passage through the coiled pipe 0. Vhen the waterin the tank is heated anditis desired to charge the boiler A, then the valve G is opened,which causes the'water in the tank to flow into the boiler as the steam-pressure 1n the tank D and in the boiler A is equalized, and the tank D is thereby entirely or partly emptied, after which the valves E and G are again closed, and the valve I is opened, so as to refill the tank with fresh water, and the above operation is repeated. The water in the tank D is also heated by the exhaust-steam passing through the longitudinal pipes K.
It will be seen that the water in the tank D is heated to nearly the same temperature as the water in the boiler, and all organic matter or other impurities are thereby deposited in the bottom of the tank D, and can be easily removed when the valves I and G are closed and the valves E and J are opened, so thatthe steam-pressure forces the water in the tank and the impurities in the bottom of the same out through the blow-off valve J.
For locomotive-boilers the tank D is arranged as shown in Figs. 3 and 4., and the water is discharged from both sides of the tank by two pipes, F.
When applied to locomotives,the load to be drawn is decreased, and at the same time the traction is increased, owing to the additional weight thrown upon the drivers.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In afeed-water heater, the combination, with the-boiler, of a tank supported above the water-level of the boiler, a coiled pipe in said tank leading to the dome ofthe boiler and opening into the tank above the water-level, and a pipe connecting the said tank below its waterlevel with the water-compartment of the boiler, substantially as described.
2. In a feed-water heater, the combination, with the boiler, of a tank supported above the water-level of the boiler, asupply-pipe having a valve and connected with'said tank, a coiled pipe in said tank,communicating therewith at its inner open end above the water-level leading to the dome of the boiler, and having a valve between the dome and the tank, and a pipe having a valve connecting the bottom of therein at its inner end above the water-level, the tank with the watercompartment of the and connected with the dome at its opposite I5 boiler, substantially as shown and described. end for the entrance of live steam, the valved 3. In a feed-Water heater, the combination supplypipe K, the valved pipe- F, leading 5 0f the boiler A, provided with the dome '13, from the lower part of the tank to the. waterand with the tank D above the same, the eoileompartmentefthe boi1er,and thelongitndinal pipe 0, leading from said dome to the tank exhaust-pipes extending through the tank, 20 and opening therein above the water-level, substantially as set forth.
and the blow-out valve J in the bottom of a T 10 the tank, snbstantiallyasshown and described. ALLLANDDR WHITNEY 4. A feed-water heater for boilers, comlVitnesses: prising the tank D, located above the boiler, G130. D. GREENFIELD,
