IMPROVEMENT inteso-WATER. H ETERS FonsTAMfisoitiaas".` -1 l Spccii( ation ibrining part of Letters Patent Norllll, dated llehrunry 7, 1865.
To all ahom it may concer-fn:
Be it known that l, WILLIAu A. Lien'r- HALL, ot' the city, county, and State of New York, have invented av certain. new and .useful improved combination ot a feed-Water heater, with ,a condenser for use in and with non-condensing or high-pressure steam-engines; and I do hereby declare that the following is a full and exact description of the same, reference bein g had to the accompanying drawings, and to the letters and tigures ot' reference marked thereon, in which- Figure l is a vertical and longitudinal section taken through the line A B O D, Fig. 2; and Fig. 2 is a vertical transverse section taken through the line. E F, Fig. 1, the head-plate ot' the heater being 'removed to showT more clearly the location of the tubes in the heater. l The object and purpose of my invention is to interpose between thc engineand the con denser, into which the steam troni the engine is ultimately to be condensed, a heater into which the steam from the engine is first exhausted, and into and through which the feedwater is passed from the feedpump to the boiler, for the doublev purposeofrst heating the said feed-water to a high degree ot' temperature by its beingv heated by the passage through the heater ot' thev first iuiiux of steam exhausted from the engine,{so as to j-be restored to the boiler at a highertemperature than could be attained if the ,waterwas heated prior to -i ts being received into the feed-pump 5) and, second, of abstractin g from the exhaust steam a large percentage of its contained heat (so as to relieve the condenser from such percentage 'of its duty) that would be contained in it were the steam from the engine exhausted directly into the condenser without the in terposition of the heater.' i
My invention therefore consists in placing and iuterposin g between the exhaust of a noncondensing (or high-pressure) engine av heater, into which the steam from the engine is exhausted prior to -its entering the condenser, and into which heater the fcedwaterfrom the feed-pump is passed, to be heated on its way to the boiler. l
A is the condenser, into which the requisite supply of cooling-water is taken through the nozzle B and taken out through the nozzle C. This supply ot cooling-water is furnished by a steam-supply pump ofv required capacity, or by any other desired mcans y D is a series ot' tubes through which the cooling-water above named is passed to produce the condensation ofthe-steam exhausted fronitheengine (after the said exhaust-steam is passed through the heater, as hereinafter mentioned) bythe steam coming in contact with the exterior of the tubes, as hereinafter described.
E E E E" EH are division-plates which div-ide the condenser into six sections, as shown in Fig. l, their purpose being to force the exhausted steam received through and from the heat-er to travel an extended distance over, across, and by the exterior of the tubes in the condenser, as compared with the length of 'the 'travel oi' the cooling-water through the tubes, for the more eiiectual and thorough condensation of the same in a limited length of apparatus, it being apparent that if the division-plates were dispensed with the apparatus would require to be so greatly extended in length to produce the same effect as to be practically valueless.
F is a dripplate, having apertures in it at properly located intervals1 through which the condensed water falls into the reservoir G, from whence the said Water is taken through the nozzle ll by a pipe to the feed-pump and from thence by another pipe to the heater, as here inafter described.
lf is the heater, located (for convenience of arrangement) on top of the condenser A. .ltis fitted with tubes, as shown, through which the steam exhausted into it from the engine through the nozzle K passes to the opposite l end of it, and is from there .passed into the condenser through the pipe L to pass across, around, and by the tubes D, and around and by the division-platcs of the condenser, as is shown by the darts in Fig. l.
' M is the nozzle to the heater, to which the pipe from the iced-pump is attached, and through which the condensed water from the reservoir G, after passing through the feedpump, enters the heater to'pass across and among the tubes in the heater, and is from thence taken oft' to the boiler through the nozzle N, and through the pipe connecting that nozzle to the boiler. This feed-u-'ater is sub- .,'ectcd to the tirst e'tflect ol' thc steam exhausted from the engine into the heater,\and is, of course, heated thereby to a higherdegree of temperature than if it Vwere pumped directly tothe boiler from the reservoir G; in fact', it is-proved by experience and practice that said feed-Water can be restored to the boiler at or very nearly at its boiling-point, and therethe ordinary manner. l
O Ol are supernumerary nozzles,lto enable the heater to be attach ed convenientlyin place in the vessel or-other location whereit is to be placed, either one' subserving the purpose of thepnozz'le K, In case of one of these three nozzles being used, the others are to be closed and shut ol' by being covered by a bonnet in a Well-known manner.
As' before mentioned, the rst introduction .fore too hot to be pumped by a force-pump in vofthe steam exhausted from the engine into the heater not only heats the feed-wat erpassed into and through the Jheater to a high temper- ,atur'e to be returned backto the boiler, but it 'also relieves, by lsuchl abstraction of the heat of the exhausted steam, the work to be perv formed bythe condenser after the'steam passes into the latter. What I claim' as my invention, and ydeslre to secure by `Intters Patent, is-
The heater I, arranged 'as described, and
placed between the exhaust of a steam-engine andthe condenser A, as and for the purpose WM.A A. LIGHTHALL.
