IMPROVEMENT iN PnEvEN-rineiNcRusTATioN'oF STEAM-'Bomans The schedule referred to' in these man Patent and mixing pm p: the mme.
l, CHARLES JAMES IAnorirn DICK, of Pai-ist,
county of Philadelphia, State of Pennsylvania, have invented a Mode ot' Preventing incrustation in and Corrosion of Boilers und other vessels, of which the following is a specitication. y l
My invention consists iu preventing.incrustation in and corrosion of boilers and other vessels containing water or other liquids by continuously or iutermittently feeding into the saine, while under pressure or heated, (or in any appropriate vessel or chamber in connection therewi'tlnlzinc, or otheri equivalent uietnl or alloy.
XVith the 'view ol' preventing incrustation in and corrosion ol steam-boilers, zinc and other metals need, as,1for instance, in the English patent of B. G. Babington, No. 13,322, ot'th `November, 1850, and thebrevet taken out oy the sume person in France on 28th November, lSil, No. 52,082..
I have discovered that the want of success ol this plan, as hitherto practicethlnis been that the zine, or other metal ot' the saine electrical properties as to the metal of' the boiler, becomes coated in avery short time with layers oi' voxide and scale, by which it is completely insulated from the water. i v
Volt-aio action-is consequently 'of' short duration, ceasing within .a few days after the introduction of the metal. i When applied to boilers, tho feed-water of which is acidnlated or corrosive, the metahnsed for protecting the same is either vdestroyed or becomes insulated, as above, in an equally short space ct' time.
Iii-order to obviate this dilcnlty, I fectlinto .the boiler or vessel, while4 under 4pressure or heated, either continuously orintermittently, a wireor'ribf bon of zinc, 0r other metal or alloy more oxidizablefthan the metal of the boiler, oracquiring when thus applied, the same electrical properties withyrel spect to the said metal as has zinc, so as to proi duce a regular and continuous volt-nic current or tenf sion. f
i In the accompanying drawing- A represents a portion of a steam-bhiler, and
a, the level of the water in the saine.
13 is a coilof aline wire, one endof which is so secured to the shell ofthe boilerat b as to insure end being passed through a small stullinv-box,1,
secured to the shell of the boiler, and into t e latter, ,fr
so that it shall project below the water-line. i This /wire has 'to be vslowly fed into the-boiler,l i
either continuously or intermittently. It may be fedi lfor instance, by and between rollers caused to ref be thrust through lthe Starling-box by hand'A from j time to time.
, No determined speed with which the wire should be fed into the boiler-can begiven,eas it must vary in accordance with the' feed-water, some qualities oil which will cause a more rapid oxidization of -tbc wirev and depositof scale thereon than others, and consequently demand a faster feed of the wire, so as to always insure suliicient electrical contact between the wire and the water int-o whichr it isrbeing fed, The-continuons voltaie actionthus maintained ei- Iectualiy prevents the formation of scale on the it-.of such material, that when the wlre'passcs through Y.
it, :it shall be insulated from the metal of the boiler,
as. thisvwill enable me to apply to the wire a gailf ranorneter for testing the voltaic action within the y, boiler.. u
Although results partially elect-ive may be pro duced even when a continuously-dosed voltaic cur-. rent,as above indicated, is not maintained, snch','for instance, as by feedingthe wire through an insulated stalling-box into the water withoutits being, on the other hand, in electrical cdinmnnication with the shelllof the boiler, exceptthrough the water into which it is being fed, or also by feeding the wire into the steam-room ot a boiler without its touching the wa. ter, and connecting it, on the other hand, electrically with theshell of the boiler, by far the best results are obtained under the circumstance related bove. Alt-houghl have described my'inveution as applied to a stcain-boiler, it [hay be used in connece tion with` other metallic vessels in which watezror other liquid is heated, for preventing incrustation and corrosion, and it nay be applied to appropriate auxiliary vessels or chambers o of a boiler; a l'eedwater' heat-er, for instance, or a vessel' or chamber especially constructed auiLused for the present purpose, the necessary electrical connections being :nude so as to benefit the metal of the boiler, as ii the zinc were fed directly into the same; and although I hanealluded to zinc as the metal to be fed intol the boiier,.it shnuldbe understood-,that any other -met'al nr alloy, having'or acquiring, when thus applied,- the szimeelectrical properties as to the metal nf the boiler or www), aa has zinc, may be en1 played.
