FEED-WATER HEATER.
SPECIFICATION forming part 0f Letters Patent No. 232,342, dated September 211880. Application led August 9, 1880. (No model.)
To all whom it may concern:
Be it known that I, SAMUEL M. FULTON, of Pittsburg, county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Feed-Water Heaters; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawings, making a` partof this specification, in whichlike lettersindicating like partsp Fi gnre 1 shows, in perspective, myimproved feed-water heater arranged in a steam-boiler,
the side 'of the boiler and a part of the outer shell of the heater bein g` broken away for the purpose of illustrating the arrangement and construction of the-heater; and Fig. 2 is a sectional elevation ofthe heater drawn to an enlarged scale. Y
My present invention relates to an improvement in the class offeed-water heaters shown' in patents granted to me as follows `January 1, 1878, No. 198,737 April 16, 1878, No. 202,- 535, and June 3, 1879, No. 216,173.
The object of my invention is to give the water a longer course or passage through the heater, so as to expose it a longer time and in thin sheets or streams to the heating action before it is discharged from the heater. This is secured by giving to the water in its passage through the heating space or chamber a circumferential or spiral motion or direction of flow by means of similarly-arranged divisions or ribs in such chamber, by means of which the water is more or less spread out into thin sheets or streams, and in such condition is given a longer passage within and against the outer cover or shell ot' the heater, and thereby raised to a high temperature before bein g dis 4o charged into the steam-space of the boiler.
5o above referred to.
shell of the boiler, and on its inner threaded end'is screwed the heater G. The general form and construction of this heater is similar to that shown in `my previous patents, in which a tube, D, eXtends downward from the coupling-nut D', and discharges through its open end into the bottom of an inflow-chamber, E', which is inclosed by the cylinder E. Escapepassages c in any desired number are made at the upper end or edge of this cylinder, through which water passes in jets'or small streams toV the heating-space inclosed between the cylinderand the outer hood or shell, F, which hood is cup-shaped in form, closed above, and dips t tween the cylinder and hood, thereby forming guides, channels, or deiiecting-ways a', which tend to give the water motion around or part way around the inner face of the hood as it passes to its discharge. I prefer to-arrange these ribs in a continuous spiral, as shown, so
Athat the water may have comparatively an uninterrupted iiow around the heating-space; but I do not wish to limit my invention to this particular form, as several independent ribs may be employed, which may extend entirely or part way around, and thereby givethe water more or less of a circumferential motion, as described. I also prefer to leave a little space between the ribs a and theinner face of the hood or shell, so that part of the water may flow over the ribs, and thereby be spread out into comparatively thin sheets and be heated more highly by its contact with the surface of the hood than would be the case were it to pass out to the discharge in an undivided or uniform body, as heretofore.
ABy providing the intermediate channels, a', between successive ribs, a larger amount of water can pass through the heater in a given time, and also such water is kept against or IOO feed-water to the highest possible degree are Well known and are very important; and I have found by actual aud extensive use that a heater of the class referred to will, with this improvement, heat the water passing throughv it to a much higher temperature than without such improvement.
By the terni class,7 as herein used, I mean and include heaters in which the waterin the heater passes to its discharge through an aunnlar heating space or chamber within and inclosed by the outer shell, so as to be heated by its contact with such shell.
I claim herein as my inventionl. In a feed-water heater having therein an annular waterpassage or heating-ch amber between its iniiow-chamber and its outer case or shell, and in combination therewith, one or more ribs or divisions, a, arranged in a spiral or circumferential direction around or part Way around such heating chamber or passage, substantially as and for the purposes set forth.
2. In a feed-water heater, the combination of interior inilowchamber, E', having escape port or ports c at its upper edge, an outer shell or hood, F, open at its lower edge, and one 0r more ribs, a, arranged in a spiral or circumferential direction around or part way around the space between the hood and inflow- .chamber, substantially as set forth.
3. In combination with hood or shell F and iuclosed cylinder E, forming` a heating-chamber, with inlet at the top and outlet at the bottom, asdescribed, one or moreribs, a, arranged spirally around such heating-chamber, with channels or passages a between successive ribs, said ribs projecting fr oin the outer face of cylinder E toward but terminating short of or within the inner face of the hood or shell, substantially as and for the purposes described.
In testimony whereof I have hereunto set my hand.
