FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 410,517, dated september 3. 1889- Application iiled April 24, 1889. Sen'al No. 308.386. (No model.)

To aZl whom t may concern:

Be it known that I, MAX HECKING, a subject of the Emperor of Germany, residing at Dortmund, in the Province of Vestphalia, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Apparatus for Heating and Purifying the Feed-Water of Steam- Boilers; and I do hereby declare that the following is a feill, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to construct and use the same,reference being had to the accompanying drawing, which is a perspective isometric view of my apparatus, with some of the parts broken away to show the interior construction.

My invention relates to devices or apparatus for feeding water to steam-boilers of that class which are provided with means for purifying the feed-water before it is fed into the boiler, so as to avoid undue sediment in the boiler, and has for its object to so construct an apparatus of that class as to utilize the exhaust-steam from the engine for heat-ing the water.

Vtlith this object in view my invention consists in the detailed construction and combination of parts of the feed-water heating and purifying apparatus, which will be hereinafter more fully described and claimed.

Reference being had to the accompanying drawing, the letter B denotes the well or reservoir from which the feed-water is drawn in the first instance through the suction-pipe a., which connects with the pump p through the valve d', having athree-way cock d2 and short connecting-pipe d. The valve-cock (Z2 being adjusted, as illustratedon the drawing, the feed-water is pumped in the direction of the arrows, through pipe l) and the air-compressing chamber NV, into the spraying-pipe o', which is provided with a rose b2 at its upper end, projecting into the lower part of the open-mouthed drum or cylinder D. The latter is mounted upon and forms an upward extension of aclosed tank or receiver R, which is placed at a suitable elevation upon a scaffold or supporting-frame C. This tank R is provided on one side near..its top with a faucet u, and in the top with the escape pipe or funnel c. Y

Projecting through one side of tank R is a pipe E, having an enlargement or chamber O, in the top of which is fastened a vertical tube F, of glass, or of metal with a glass strip or window running its entire length and open at the top. Chamber O connects, by a pipe G having a valve g, with the bottom of a second tank or reservoir R', having a faucet j', and provided near its bottom with the pipe e, leading to and communicating with the pump p', from which another pipe 7L leads to the boiler.

The mouth or upper end of the cylindrical drum or extension D maybe closed by means of a Valve t', and is provided with a pipe j, open at its outer end and having a branch pipe la, which communicates with the exhaustports of the engine. At the junction of these pipes j and k is a three-way valve l.

Having in the foregoing described in detail the construction of the apparatus,I shall now proceed to describe its operation, which is as follows: The valve t' in the top of drum D having been closed and the three-way valve Zad j usted, as shown in the drawing-#26., closing the outlet-pipe j and opening communication between the steam-pipe 7.5 and the drum-steam will enter the drum D and at the same time pump p is set working, which pumps water (valve-cock d2 being first properly set or adjusted) from the reservoir B into the lower end of the drum or cylinder, delivering the same through the sprayer or rose h2 in the form of a fine continuous spray. Meeting the jet of steam from. pipe k, (indicated by the arrow,) the spray is thoroughly heated and projected to the bottom 0f tank R, the excess of steam which has not been condensed by the spray passing off through pipe c.

The level of the hot water in tank R may be ascertained by means of the gage-glass F, and should the tank become too full the excess of water may be drawn off through the faucet u.

The hot water in tank R escapes through pipe E, chamber O, and pipe G into the sediment-collecting tank R (valve gbein g open,)

IOO

from which the mud or fluid sediment may be drawn off through faucet f, while the clear feed-water is fed to the boiler through pump p and pipe h.

The steam for operating the feed-pump p is supplied from the boiler through pipe h.

If it is desired to reheat the water in tank R before .feeding it to the secondary tank R and the boiler, then this may be accomplished in a simple and expeditious manner by closing valve g in pipe G and so adjusting valve d as to shut off connection with pipe a, but open it with pipe fm, which results in pump p circulating the water for any desired length of time from tank R through pipe E, chamber O, pipe m, with its connecting part or branch of pipe G, valve d', pipe cl, pump p, and pipe b b into the cylinder or dome D and back to tank R. Thefeed-Water having been heated in this manner to the proper degree of temperature, valves CZ and g are readj usted, and the feed-water is now drawn froln tank R into the sediment or secondary tank R', ready to be fed to the boiler.

By heating the feed-water in the dome D in the form of a finely-comminuted spray, the impurities in the water are projected in great part in the form of sediment into the bottom of tank Rk below the outlet E, and may be drawn off at suitable intervals through the bottom pipe o. Such liner particles as are not projected to the bottom of this tank, but pass with the feed-water through pipe G, will settle in the secondary tank R', as a1- ready described, before the feed-Water reaches theboiler.

By opening thc valve t' in the top of the Having thus described my invention, IV

claim and desire to secure by Letters Patent of the United States- The herein-described apparatus for heating and purifying the feed-Water for steamboilers, consisting of the following combined and (zo-operative parts, Viz: tank R, having pipes c and v and faucet u, heating-dome D, having valve 'L' and branched pipe j 7s, provided With the valve l, water-pipe b b', having air-chamber W and rose or spraying nozzle b2, discharge-pipe E G,having gage-chamber O, provided with the gage-glass F and valve g, secondary or sediment tank R', connecting-pipe e, feed-pump p', suction-pipe` a', valve d', having three-way cock d2, connecting-pipe d, pump p, and branch pipe m, all constructed and combined to operate substantially in the manner and for the purpose herein set forth.

MAX HECKING. W'itnesses:

D. J. PARTELLO, FRITZ POTTHART.
