' Application February 29, 1,948, seriarNo. 12,130 In Switzerland October 14, .i341
Section 1, Public Law 690, August 8, 1946 Patent expires October 14, 1961- This invention relates to Aboilers for hot water circulation systems and particularly to a heater for insertion in such boilers and connection to the hot water circulating system supplied with circulating hot water from the boiler.
One of the prime objects of the present invention is to improve the eiiiciency of such boilers by placing an additional heater in the fire space of the boiler.
The additional heater is formed by a body of circulating tubular members the outlet of the system being connected to the outflow tube of the boiler circulating system while the inlet is connected to the return pipe of said system.
A part of the water flowing in the boiler system thereby circulates in the heater.
A further object of the invention is to provide heaters adapted to the firing system of the boiler.
Still other objects of the invention are flexible connecting pipes between the heater and the boiler hot water circulating system and an arrangement permitting the displacement of the heater in the fire space of the boiler with respect to the latter.
To the accomplishment of the foregoing and such other objects as will hereinafter appear, my invention consists in the disposition and arrange ment of the heater tuberelements as hereinafter particularly described and sought to be defined in the claim; reference being had to the accompanying drawings which show preferred embodiments of my invention and in which Fig. l is a vertical section through a heating boiler provided with the heater inside its fire space,
Fig. 2 is a perspective view of another form. of a heater, and
Fig. 3 is a perspective view of a third embodiment of a heater.
The heater shown in Fig. l is composed by a row of vertically disposed tubes I connected by their lower and their upper ends to horizontally arranged tubes 2 and 3. plane of the tubes I, 2l and 3 one or more U- shaped tubes i extend vin the re space of the boiler 5. The whole tubular body I, 2, 3 and i may be built up by tubes welded together or may be of cast iron. The boiler is inserted in the well known manner in the outer circuit oi the heating system by means of the outflow pipe 6 and the return pipe 'I.
The heater itself is connected to the outflow pipe 6 through a conduit 8 and by the conduit 9 to the return pipe 1. In the conduits t and Q iiexible hoses I6 and Ii are respectively disposed.
roxane. '(01. isti-275') At right angles to the ing system of the boiler.
rI'he conduits 8 and 9 are led through the rear wall of the boiler 5. For this purpose stuffing boxes I2 are secured in this rear wall. These stuing boxes permit a displacement of the heater relatively to the boiler to make the proper adjustment in the re space.
While at Figure l is disclosed an arrangement in which the U-shaped tubes are of different lengths as regards their connections to the respective vertical tubes I and in which arrangement each vertical tube i has the tubes i connected therewith, the modification of Figure 2 illustrates the invention in the form in which the tubes i are connected to alternate vertical tubes i. In the arrangement shown in Figure 3 the tubes Ia have upper and lower vertical portions and include an integral forwardly extending elongated U-shaped portion 4a.
It is therefore clear that the present invention provides a heater for insertion in a boiler having a major and a minor axis, and which heater is adapted for connection with the water circulat- T'ne boiler of course is provided with a bottom upon which a fire bed is built up and the heater provides a tube arrangement adjustabiy supported for movement within the boiler and along the major axis thereof. This tube arrangement is spaced above the bottom of the boiler, overlies and subdivides the re space and includes vertically spaced horizontally disposed collecting tubes that extend transversely of the major axis of the boiler. A plurality of substantially elongated U-shaped tubes are in communication with and project forwardly of the collecting tubes. These U-shaped tubes overlie the main fire area of the boiler and include vertically spaced legs and a bight portion connecting the legs. As shown in the drawings, the bight portions are spaced forwardly of the collecting tubesa distance greater than the spacing between the legs at points immediately adjacent the collecting tubes, this structure resulting in a prolongation of these Ushaped tubes so that these tubes are directly in the iire Zone. The tube arrangement is completed by the flexible tubes I5) and Ii connecting the conduits 8 and 9 to the inlet and outlet cf the main circulatory system of the boiler.
The three embodiments heretofore described are particularly adaptable for use with boilers heated with solid fuels such as coal or coke.
While I have shown my invention in several preferred forms, it will be obvious that many changes and modiiications may be made without departing from the spirit of the invention.
- major and a minor axis and a water circulation system including an outflow and an inflow, said boiler having a bottom and said heater providing a tube arrangement adjustably supported within the boiler for movement along the major axis spaced above the bottom of the boiler, overlying and subdividing the re space of the boiler and including vertically spaced horizontally disposed collecting tubes extending transversely of the major axis of the boiler, a plurality of substantially elongated U-shaped tubes in communication with and projecting forwardly of the collecting tubes, said U-shaped tubes overlying the main fire area of the boiler and including vertically spaced legs and a bight portion connecting the same, said bight portion being spaced forwardly of said collecting tubes a distance greater than the spacing between the legs adjacent said 4 collecting tubes, and means connected to the collecting tubes and connected with the outflow and inow of the Water circulation system of the boiler.
