r02 LEXA NDEE ATTiQ/VEYS N w W 2 C C. Z. ALEXANDER STEAM BOILER Filed July 27, 1950 Jan. 5, 1954 Patented Jan. 5, 1954 UNITED STATES PATENT OFFICE STEAM BOILER Carl Z. Alexander, Madison, N. J.
Application July 27, 1950, Serial No. 176,235
2 Claims.
This invention relates to boilers and more particularly to steam boilers for domestic heating.
It is an object of the instant invention to expedite the generation of steam in boilers without materially increasing the fuel consumption.
A further object is to provide a steam boiler of simple and inexpensive design.
Other objects of the instant invention will become apparent in the course of the following specification.
In the attainment of these objectives, the boiler is formed with three vertically spaced water sections, the opposed surfaces of which are of wave form to provide two circuitous passageways for the products of combustion through the sections from a fire box upon which the sections rest. In each water section is a geyser fountain extending from the bottom upwardly above the water level and terminating in an outlet directed toward the wall of wave form. The heat generated in the fire box forces the heated water in the bottom of the sections upwardly through the fountains where the preheated water emerging with the steam from the fountain is quickly turned into steam on contact with the wave form surfaces forming the flue passageways. Means are provided in each section for maintaining the water level uniform together with the usual indicators for operating and means for withdrawing the generated steam from each section and introducing water therein.
The invention will be more clearly understood when taken in conjunction with the accompanying drawings showing by way of example a preferred embodiment of the inventive idea.
In the drawings:
Figure l is a side elevational view of the steam boiler constructed in accordance with the principles of this invention with a portion of the cover broken away to more clearly show the internal construction;
Figure 2 is a sectional view along 22 of Figure 1; and
Figure 3 is a sectional view along 33 of Figure 1.
Referring now in greater detail to the drawings where like reference numerals indicate like parts, reference numeral l indicates one of the outer water sections, II the other outer water section, and I2 the central water section.
Each water section is a vertical water tight container of suitable heat resisting material and horizontally spaced apart as most clearly shown in Figure 2. Each section has a cross-sectional form somewhat similar to that of a rectangle except for the opposed surfaces of wave-like form, described later. Each end section is constituted of the spaced parallel side members I3 and M (Fig. 3), spaced parallel front and back members I5 and ii, the top member I! (Fig. 2) and the bottom member 18 attached in any suitable manner along corresponding edges. The front and back members may be common to all three sections with the side members welded in place.
The side member I4 has vertically spaced alternate projections and recesses for the length thereof, the cross-sectional form of which is that of a sine wave with flattened crests and troughs. It will be noted in Figure 2 that the crests and troughs of the surfaces of each outer section that is, the surfaces that face each other are aligned.
In each of the outer sections Ill and H are the similar geyser fountains or thermo-siphonic means I9 and 2|), respectively. Each geyser fountain is constituted of a hollow elongated base member M of rectangular cross section along the bottom edges of which are openings 22. Through the top of each base member 2| is a tube 23 extending above the water level 26 and terminating in an inwardly directed curved outlet directed toward a trough of a wave as shown in Figure 2.
In each outer water section I0 and II and coacting with the outlets of the geyser fountains I9 and 20, respectively, is a dam 25 longitudinally disposed intermediate the trough and crest of consecutive waves over which the fountain outlets protrude. The dams extend substantially for the length of the sections and are positioned above the water lever 24.
Intermediate the outer water sections in and II is the central water section l2 of similar construction to that of the outer sections except that both of the surfaces which face the outer sections have alternate horizontal projections and recesses of flattened sine wave formation. However, the wave formation of the spaced side members 26 and 21 of the central section 12 while aligned with each other have the wave crests aligned with the troughs of the outer sections and the troughs with the crests of the outer sections. It will be noted in Figure 2 that the troughs of the waves of the central section are constricted to form a substantially vertical passageway. By this arrangement two circuitous passageways are formed for the products of com- 3 bustion between the fire box and the flue (not shown).
Within the central water section I2 is a geyser fountain or thermo-siphonic means 28 similar in all respects to the previously mentioned fountains l9 and 20 except that the head is of dual form as illustrated having one outlet directed in curvilinear form toward the interior of the trough of one wave on one side and the other outlet oppositely directed toward the interior of the trough of the aligned wave.
Any suitable system of inter-connecting pipes 29 having outlets in each of the three water sections and communicating with a common water supply may be used to maintain the water level in each section uniform while a similar pipe system 30 inter-connecting the tops of the water sec tions may be used for conducting the steam to the radiators. The steam pressure guage 8i and water level guage 32, both of known type, may be used also.
The vertically spaced water sections HI, I l, and II are supported by any known means above the fire box 33 which, as illustrated, is designed for gas but readily adapted to other types of fuel.
Around the water sections and fire box is the jacket 34 spaced from the water sections for the insertion of any suitable insulating material as illustrated and through which openings (not shown) may be provided for various servicing operations.
In operation, assuming that the boiler is filled to the level 24 shown in Figure 2 and the heat turned on, the water in the bottom of each section will be first heated and rise in the geyser fountains. The end fountains l9 and 20 direct the preheated combined steam and water against the troughs of the wave like walls of the passageways where the water is quickly converted into steam. Excess water is caught by the dams 25 to be momentarily retained near the heated passageway for conversion into steam. In the same manner, heated water will rise in the central geyser fountain 2B and combined with steam will be forced outwardly against the inner surfaces of the aligned wave troughs, the excess water trickling downwardly over the sloping surfaces heated by the products of combustion to be turned quickly into steam or to absorb heat and mingle with the main body of water.
It will be understood that the invention is not limited to the exact disclosure herein described but may lend itself to a variety of expressions within the scope of the appended claims.
What is claimed is:
l. A steam boiler comprising a fire box, two outer and a central water section disposed above the fire box in spaced horizontal arrangement, the spaces between the sections communicating with the fire box and the opposed surfaces of the spaced sections being of wave form, the waves havin crests and troughs in substantially horizontal arrangement and the crest and trough of each wave being flattened in substantially vertical planes, the flattened crests of the waves of the outer sections being aligned with each other and with the flattened troughs of the waves of the central section, the troughs of the waves of the central section further forming constricted passageways therebetween in substantially vertical alignment, means for enclosing the water sections and the fire box, and a geyser tube disposed in each section for directing the water from the bottom thereof against the inner surface of a crest of a wave in said section above the water level.
