FURNACE Application filed September 13, 1927. Serial No. 219,246;
This invention relates to water heating furnaces, particularly of the class built in superimposed water sections forming a retarding smoke flue and oifering greater heating surface thereby.
The principal object of this invention is in the construction of the water sections, which cause the smoke to circulate around tubular water chambers entirely before being forced to escape through the central portion thereof.
Another object is also in the construction of the water sections, which cause a double action of water. circulation, afforded by a pair of headers.
A further object is to provide a means of metal surface expansion, in and between the several sections, so as to eliminate all danger of cracking.
Other objects and advantages will be further disclosed in the following description and in the accompanying drawings, in which Figure 1 is a vertical central view of the invention, looking towards the rear thereof.
Figure 2 is also a vertical central View, taken on the line 22 of Figure 1.
Figure 3is another vertical sectional view, taken on the line 3-3 of Figure 2.
Figure 4 is a side elevation, partly sec-' tioned, taken on the line 4-4 of Figure 3.
Figure 5 is a horizontal sectional view, taken on the line 5-5 of Figure 4:.
Figure 6 is a view in elevation, partly sectioned, of one of the headers, taken on the line 66 of Figure 5.
Figure 7 is a similar view, of the other header, taken on the line 7-7 of Figure 5.
Figure 8 is a fragmentary View, similar to Figure at, but showing a modified structural detail.
Figure 9 is a horizontal sectional View of the modification, taken on the line 9-9 of Figure 8.
Figure 10 shows one of the headers of the S3138, taken on the line 10-10 of Figure 9, an
Figure 11 is a view of the other header of same, taken on the line 1111 of Figure 9.
Similar reference characters represent similar parts in all the views.
A base 12, having a grate supporting frame 13 within its top, supports a fire pot 1 1 having a header base 15 on each side of its top, upon which several water sections are mounted. The lowest section 16 is preferably shallow and consists mainly of cylindrical horizontal passages 17 evenly spaced between the side portions of the surrounding chamber thereof. The upper sections are formed in pairs, 18 and 19 having three smoke flues 20 and the other pairs 21 and 22 having two flues 20. Any number of pairs can be thus super imposed in sequence of two and three flues 20. These flues 20 are made through the inner wall of semi-cylindrical water passages 23 evenly spaced horizontallly between the side portions of the surrounding chamber thereof. The uppermost section 24: is of an inverted cup-shape and forms a dome, to the furnace, out of the sides of which are passages 25 properly flanged for connection with headers 26 and 27. Another passage 28 is formed at the rear of section 24 to be con nected to any system of circulation.
An ash door 29 is suitably made into the front of the base 12. The fire pot 14 comprises a suitable door 30, for feeding fuel, a door 31, for draught control, and a main passage 32, leading into its surrounding water chamber, to be connected from any supply. The surrounding chambers of all sections, 16, 18, 19, 2-1, 22 and 24, are placed in line above the chamber of fire pot 14. All sections 16 are furthermore projected beyond the front portion of the fire pot l t and all the sections, including section 16, moreover extendbeyond the rear thereof. Sections 19 and 22 do not project rearwardly, and the space that would be occupied by their ex- 9 tended portion is filled by an upward extension of the sections 18 and 21. It will thus be understood that sections 19 and 22 are fitted into the angular rear portion of sections 18 and 21, leaving a slight vertical space 33 between the walls of each pair thereof, which will permit expansion and contraction therebetween. Furthermore, all pairs of sections, 18 and 19, and 21 and 22, are also vertically split and walled, for sideways expansion and contraction, in one place 34 between passages 23.
The headers 26 and 27 are firmly secured at their base upon the fire pot header bases and at their top to the flanged passages Along the sides th'ereofare flanges 35 and 36, integral with a walled face 37 having Jertures 38 and 39 leadin res ectivel into l in chambers 40 and 41.
The sections 16, 18, 19, 21 and 22, have flanged passages 42 registering with the apertures 38 and 39 in the header faces 37 V and to which they are securely bolted. The apertures 38 correspond with the passages 42 of thesections 16, 19 and 22, while the apertures .39 correspond with the passages 42 of the sections 18 and 21. Chamber 40 of the'header 26 and chamber 41 of the header header 26 must-come from the base 15 and.
that it passes through the apertures 38 of the header 27 to enter the dome section 24 and vice versa. Thus, an opposite direction is established in the water around the entire furnace, between each adjoining section.
Thefront portion of all the sections is exteriorly fastened to a common frame 43 bearing a suitable door 44 having inwardly mounted slats 45 closing a space 46 purpose- 1y left between each pair of sections 18 and 19, and 21 and 22, for conveniently cleaning the soot formation therebetween.
The rear portion of all the sections is exteriorly fastened to a common housing 47 having a smokestack aperture 48. Any soot collecting. therein can be expelled through suitable opening 49.
It will be apparent that this construction presents an exceedingly large heating surface unto a considerably small volume of watcr that must necessarily circulate very rapidly to coverthe extensive passage formed therein This, in other words, means that a very rapid heat transfer is obtained and can be maintained with a very small amount of kindling or very little attention. consequence is also noticeable due tothe fact that the direct heat and the hot fumes are circulation,,,
This
given time to be well spent during their passage between the lower sections up to under the dome section 24 and, towards the front, within the frame 43 to enter into and along the fines 20, before they reach the smoke housing 47 and, until then, do not cease being effective.
One point, which may have its importance, is that in case a water hammer should be formed when the not water is circulating, a relief can be provided in making a small aperture 50 at the top of the wall separating the chambers 40 and 41 of the headers 26 and 27.
A modified construction is shown in the Figures 8 to 11 inclusive. This difference concerns the manner in which the expansion and contraction is effected. The sections 19 and 22 extend rearwardly as far as the Water chamber of sections 18 and 21, which have an intercommunicating passage 51, permitting an immediate relief of the hot water circulation. This manner of level circulation eliminates the necessity of raising the rear portion of the sections 18 and 21 as shown at the space The sideways expansion and contraction is maintained by the space 52 in practically the same manner as that shown in place 34. The apertures 39 of the headers 26 and 27 are lowered one step, so as to be in alignment with the flanged passages 42 of the sections 18 and 21.
This modification is here shown to exemplify the manner in which changes can be effected, without departing from the spirit and scope of this invention, and in which I desire to be fully protected.
lVhat I claim as my invention is 1. In a water heating furnace, a base, a fire pot having a surrounding water chamber with an intake main passage and having a header base disposed upwardly on each side, superimposed water sections having separate cylindrical passages leading into a surrounding chamber and so arranged as to cause the water to circulate in opposite direction in each of said sections, the uppermost section forming a dome having an outlet passage, two headers communicating with the-water chamber in said fire pot and all of said sections, and means for causing the circulation of hot gases through and between said sections, the said sections, intermediately being made in pairs and having their rear portions split and walled so that a space is left vertically between them fort-he purpose allowing expansion and contraction thereof, substantially as described.
