5 Claims.
'This invention relates to an improved steam boiler that combines the percolator principle in addition to the normal heating function of the boiler sections.
The invention provides a compact boiler with convenient and efcient feeding and blow-off connections. The boiler is of a construction that makes it possible to use cast or sheet-metal sections, the latter being preferred.
The invention is illustrated in the accompanying drawings in which Figure 1 is a longitudinal vertical section of the improved boiler. Figure 2 is a section on line 2-2 in Figure 1. Figure 3 is a section on line 3-3 in Figure 1. Figure 4 is a perspective View with the casing broken away to more clearly show the construction and the iire passages.
The boiler is encased in an outer shell or casing I which is lined with a heat resisting material shown at I I.
The boiler comprises sections, the bottom one being spaced from the floor by a supporting frame I2 and is raised to provide a re-box I3 into which the oil burner I4 projects the llame for heating the boiler. Other forms of fuel, can, of course, be used with the usual alterations necessary for such use.
The boiler sections are arranged horizontal, spaced apart, and disposed one above the other. They are so constructed as to be duplicates, each being reversed end to end relative to the next adjacent section or sections. The boiler shown in the drawings has three sections.
The bottom section I5 is supported on the base or bracket I2, the central section I6 is spaced from the bottom section I5 to form a flue space and the top or uppermost section Il is spaced from the central section to form a flue space, the flue spaces being identiiied by arrows in Figure 4 at I8. The sections are set back from the casing at the ends to form ue ducts I9 and the smoke pipe 20 connects the heater with a chimney.
Each section has a well 2l preferably at one end. The well is open to the inside of the section. The top"wall of the section has an opening 22 above the well. The sections also have openings 23 in the bottom wall at the end opposite the well and arranged to be above the opening 22 of the next lower section when the sections are assembled. The openings 22 and 23 receive a tube or nipple 24 which serves as a water passage and also provides space for a percolator tube.
The percolator tubes are placed in each well except the top one and are shown at 25. Each percolator tube has a base 26 with inlet spaces 21 and extends from one well to a point above the bottom of the next higher section and has a horizontal outlet 28. The tubes 24 that connect the sections extend above the bottom of the upper section of the two as shown at 29. This insures a water level on the bottom of each section and the overow passes over the rims 29 into the next lower section.
The feed pipe for supplying water vto the boiler is shown at 30, is provided with a valve 3| and feeds water to the top-most section, the water flowing down from one section to the other until the proper water line in the bottom section is indicated on the gauge 32.
The top-most section has the opening 22 connected to the steam pipe 33 and the return pipe from the steam system is shown at 34, connected to the bottom section.
The top-most section has no percolator tube in its well which is supplied at its bottom part with a blow-oil pipe 35 provided with a valve 36.
In operation, the water in each section is converted into steam, which action is hastened by the steam and hot water passing up the percolator tubes and being deposited on the relatively shallow water in the next upper section. This also insures water in such section, the hotter the boiler the more water is deposited through the percolator tubes.
The boiler may be made of cast metal but sheet steel is preferred as it is readily assembled,
-and brazed and welded connections can be made.
The flow of water from each section into its well 2l is free but the opening 23 is provided with a raised rim by any desired construction but the preferred form is to extend the sleeve or tube 24 above the bottom of the section over which extension the water must pass in flowing back to the next lower section.
The water and steam in being carried up by the percolator tubes carries impurities and solids with it and these are deposited in the well 2| of the top-most section. This accumulation can be drained through the blow-ofi pipe 35.
The tubes 24, connecting the sections are large enough to allow a fre passage of steam and an unobstructed return flow of water .around the edges. The steam is aided in its flow toward the steam pipe 33 by the emissions from the percolator tube outlets which extend in the direction of natural ow of steam toward the pipe 33.
Various changes can be made in the construction and proportion of the parts without departing from the scope of this invention.
I claim:
1. A steam boiler comprising a series of horizontal sections arranged one above the other in spaced relation and provided with wells, and with steam openings comprising conduits above the wells connecting each section, the alternate sections being reversed relative to the others percolator tubes in the wells and extending through said steam openings to deliver to the next higher section, the conduits having projecting rims on their top edges for insuring the presence of water in the sections.
2. A steam boiler comprising a series of horizontal sections arranged one above the other in spaced relation and provided with wells, and with steam openings comprising conduits above the wells connecting said sections with the next higher section, the sections being arranged alternately in reverse position percolator tubes in the wells and extending through said steam openings to deliver to the next higher section, the conduits having projecting rims on their top edges for insuring the presence of water in the sections and a valved blow-off pipe extending to the outside of the boiler from the lower part of the well of the top-most section.
3. A steam boiler comprising a series of horizontally arranged hollow sections, one above the other in spaced relation, each section having an opening in its top and a well below said opening, percolator tubes in the Wells other than that of the 'top-most section, each section having an opening in the bottom above the opening and Well in the section next below, conduits connecting said top and bottom openings of adjacent sections the percolator tubes extending from a Well through such conduits to the next section above and with its outlet arranged horizontally to project into the next section, the rim of each bottom opening being raised to insure the water level in each section above the bottom thereof and a feed water pipe for feeding water to the top-most section.
4. A steam boiler comprising a series of horizontally arranged hollow sections, one above the other, each section having an opening in its top and a well below said opening, percolator tubes in the Wells other than that of the top-most section, each section having an opening in the bottom above the opening and well in the section next below, conduits connecting said top and bottom openings of adjacent sections the percolator tubes extending from a well through such conduits to the next section above and with its outlet arranged horizontally to project into the next section, the rim of each bottom opening being raised to insure the water level in each section above the bottom thereof, a feed water pipe for feeding water to the top-most section and a valved blow-oil pipe extending from the lower part of the well of the top-most section.
5. In a steam boiler, a boiler section of fiat form with a well in the bottom at one end, an opening in the top wall above the well, and an opening in the bottom at the other end, the last mentioned opening having a raised rim.
