SPECIFICATION forming part of Letters Patent No. 737,346, dated August 25, 1903.
Application filed February 13, 1902. Serial ITO-93,818. (No model.)
ent in Great Britain, No. 15,059, dated July- My invention consists of an improved steam-generator of the type known as flash steam-generators in which I employ a tube in a continuous coil surrounding an oil or spirit burner and forming itscasing, in conjunction with a steam-receiver, which also acts as a superheater for the steam generated in the coiled tube.
The invention is illustrated upon the ac- 2o companying drawings, upon which- Figure 1 is alongitudinal section, and Fig. 2'is a cross-section of the same. Fig. 3 is an elevation, on an enlarged scale, of one of the distance-pieces arranged upon a tube.
I provide a continuous pipe a, arranged in a coil and the coil after being continued to the end of the casing 12 is returned within or around itselftwo .or more .times, forming other coils concentric with the first. The
pipe at, which is preferably of uniform bore,
pieces are made of fire-clay or other refrac heated gases free access to the tubes.
tory material, and they serve tokeep the adjacent tubes apart and to break up the heated gases during their passage between thecoils. The ferrules are cut away at e to allow the The distancepieces are preferably arranged as shown in Fig. 3, the ferrules abutting against one another.
The burner employed to heat the water may be an oil or spirit burner of any ordinary construction, and it is arranged within the.
coils a, a space being shown left for the purpose, although the burner need not be shown. The casing 19 is preferably formed as a double wall containing asbestos or similar non-' conducting material. 1
The diameters of the pipes a and d are propo'rtioned one to the other. A suitable proportion is one to four; but any sizes and proportions maybe used.
Feed-water is injected under pressure into the outer end of the coiled tube a and is flashed into steam as it passesthrough the heated coiled tube. The steam thus formed passes into the outer receiver cl. A suitable check-valve is arranged upon the exterior of this tube a to control the supply of feedwater.
. To the outside of the casing 12 is attached a chamber h, to which is secured a chimney 'i, and within the chamber h is arranged a coil 9, through which the exhaust from the engine is ca'used'to pass before entering thev chimney and escaping to the atmosphere. By this means the immediate condensation of the exhaust-steam is avoided, and it leaves in' which the feed-water is flashed into steam,
an outer larger coilarranged around said inner coil and acting as a steam-receiver and superheater, and an arm exterior to said coils connecting said outer' superheating boilercoil directly to said inner generating boilercoil. .i c
2. A flash-boiler comprising an inner. generating-coil in which the feed-water is flashed into steam, an outer larger superheating-coil enveloping said inner coil, an arm directly upon said coils, flanges to said ferrules, and :0 connecting said outer coil to said inner coil, perforations in said flanges and ferrules.
and a jacketed casing Within which said coils In Witness whereof I have hereunto set my are located, said connecting-arm between the hand in presence of two witnesses.
5 boiler-coils being outside the casing. V 4 w 7 3. A flash-boiler comprising an inner coil, JOHN SNELL CHENHALLS' an outer larger coil arranged around said in- Witnesses: ner coil, an arm connecting said outer coil to SYDNEY ASHDOWN,
said inner coil, ferrules of'refractorymaterial VICTOR F. FEENY.
