, vapor orgas accumulation space inthe upper chamber 'Arn object of th'e inventionis to provide means ofrapidly' generating and collecting'steam or other vapors ,under 'pressure.
7' Another object. is toprovide;forexpansion J and I contraction of the ,parts, so that ;n'o"idistortion and consequent leaks will occur infthe ra or j The invention possesses otheradvantages,
someof Which, with those referred to above will' be described-in d c iption Inthe drawings:
Figure 1 is an elevation of a vapor genera- 'tor madeyin accordance with my invention, with the casing sectioned so as to show the construction of the vaporgenerator. Figure (2 is a view of the circulation system, Figure 3 is a View of'a circulation systeinwith the circulating coils beginning and ending in the horizontal drums insteadof in the upright stand-pipes as shown in Figure 2. v
Referring to: the drawings by reference characters 7 and 8 are horizontal tubular metal drums, 9 and 10 are upright tubular metal stand-pipes suitably secured to-and in communication Withthe drums 7 and-8 so as to form a continuous rectangular passage-way s or chamber. The stand-pipes 9 and ,10 and detail in the following the drums-7 and 8 are preferably secured together by autogenous Welding as shown in the drawings but may be fabricated in any suitable manner. The coils 6, 6 are-metal tubes preferably helically coiled with a coarse pitch so as to-cause the liquid circulating "through themtotravel at a high rate of speed. Said coils 6, 6 may start in the lower end of one of the stand-'pipessuch as 1.0and end in the other stand-pipe. The interior of these a coiled tubes 6; 6 is in communication at both ends with'the interior of the stand-pipes which are suitably secured into them, preferably by-autogenous welding. 5 is aftube for conducting escaping vapors. 15 is armu'di and rial The liquid supply 'pipe 3 is spirally or may be oftheeirpan'ding' tubetype; said regul'ato'ris. not claimed as'new; one purpose d i b n fi l 161's a tube fbfr replenishing the uppl ofliquiidi a In Figure 1, 1 s 'ar'casingenclosingtheenliquid vaporizing system, said casing be- 1 mg {composed .of 'any; suitable refractory and insulating materialsuch as moulded asbestos board or-infusorial earth, or magnesium carbonate. 2iis' a val-VB .Oflthe liquid supply pipe 3; a shut-'offvalve or throttlevalve on the l elically coiled vapor and super-heating pipe 5; '6 ,1( i'-are heli c ially.ooilsd liquid ciri cula'tingftubesf referred to above "and shown in Figures 2and 3 and ,8 arethe horizontal drums connected by the stand-pipes 9fand 10,

As shownin' Figure .1 the horizontal drum or tube 7, is below the burner'an'd the arena lating "mud; sediment and scale a chance" to maintained near thecenter ofthe drum 81by any. suitable liquid .level regulating device suchasthe float and valve type 14-, as shown,
is that thedrum 8 provides a-separating sur face'to. allow the gases or steam to separate from liquid; also it provides a storage space forfithe "steam, j vapor or gases. The
standapipes-Qand 1 0 s'erveas connecting pa's sages between the two horiz ontal 'drum's 7' and 8, also serve as supports for the circulatislthereforerelativelycooler than the rest of the circulating system, this gives theaccumm 8o collect in the" drum and still not be, burned i ing coils 6; 6 I when the circulating system is formedlas shown Figure 2. ,The rectanr gular passage-way formed by the two horizontal drums 7 and 8 and the vertical stand-pipes 9 and 10 has a continuous slow circulation maintained in it by the rising column of steam and hot water in one of the stand-pipes, and
thereby carries all scale to the lower drum where it settles and can be blown out. The plurality of circulating coils 6, 6 form a large surface for'the absorption of heat and by their small cross-sectional area and their inclination cause the liquid and gases in them to circulate at high speeds, thereby absorbing a greater quantity of heat. tubes6, 6 being directly exposed to the fire or hot gases of combustion, must-expand and being coiled are free to expand without injury to their joints. The wetssteam or gases pass from the drum 8 through the super-heating tubing 5 which presents a still greater heat absorbing surface to the gases of combustion thereby extracting more heat also super-heating the steam or other gases; this tubing is Having thus described my also coiled and free to expand. The cold liquid from the source of supply passes through the economiz'er tubing 3 which is coiled inside of the exhaust stack 11 and is thus heated by the otherwise waste heat of the exhausted gases of combustion. This liquid is therefore preheated before being fed as required'to'the circulating and steam generating system composed of the horizontal drums 7: and 8 with their vertical stand-pipes '9 and 10 and the circulating coils 6, 6. The burner 12 may 'beof any suitable type and consume any suitablefuel, said burner is not claimed asnew. I r
invention, what I claim is new and desire to secure by Let ters Patent of the United States is:
