In Figs. 6, '7, and 8 I have shown o construction which will be found preferable in practice lo that shown in Fig. l.
This apparatus consist-s of a heating-cylinder B2, containing the evnpoi'ating-tiibes b b Z22, &c which are siiitziblysei; in the tubeslieets e end d et each end, so as to make tight joints. The initial tubo Zi discharges into n section composed of two tubes, which are arranged parallel to it, connection lietween the initial. pipe and the section being made by the employment of the construction described in ,Letters Petent granted to nio lila-y 22, i888, No. 383,38l-that is to say, by return-bend liezids C2 and M, provided with partitions 7i; Z, wliieli when the cover-plates K and L are in place i rm cells n n n, die., and o o o, etc.
The return-bend iioziils C2 and lli are of triangular forni, and nach is with an apex it the top. "ilie hood C2 is divided by liorizontal plates/l; into cells n 'o' n li 72, its shown in Fig. S, sind is closed 4by the outer plete K, which riveted or'bolted to its enter iienge. The bend is seem-ed by its inner flange to the tube-sheet e', and the partitioniilotes 7c are fitted to marke tight joints against; suoli tube-sheet, so as to forni tient cells oonneotiug the adjacent ends of horizontal rows of tubes. The i'etiiin-iiend lief-id M is secured to tlie tube-slieet/ Yind is provided with liorizoiital partition-plates Z, dividing it into oeils o o o of" 0, and is closed by the plate L. 'llio liquid-supply pipe l connect-s with the oell n of head C2, the pinto K heving zin Opern for siici'i purpose. Plate l. of the inner iieed M is provided near its bottoni with e horizontal opening oinleading from the bottoni cell o"",to permit the discharge of vapor :ind liquid from the lower set of tubes Z237 to Z242, inclusive. A separating-chamber A2 may be oonneeted to the apparatus when it is desired to separate the liquid ind vapor, into which the lest seriesoi tubes in the eoilslizill discharge. Ii, is shown in Figs. G, 7, and as provided. with dnslbplzites cz. o, o liquid-discharge pipe g', and e Vapor-outlet Dfi.
According to this my preferred const-rnciion and arrangement; oi' the eviiporfit-ing'n tubes, the inlet or initial evnpoi'nting'tiibe l; conneots tlie cell is, with the cello and two tubes b und b2 oonneot cell o with cell n', lieing equivalent ton- (livisionof tube l) into two neet cell it with cell o.
