Description
Patented Sept. 17, 1946 BOILER Ralph D. Terhune, Ridgewood, N. .L, assignor to The Bryant Heater Company, Cleveland, Ohio, a corporation of Ohio Application April 13, 1945, Serial No. 588,082
1 Claim.
This invention relates to boilers employed for heating buildings or the like by serving hot water or steam radiators therein; and more particularly the invention relates to such boilers of sectional construction, and to the location therein of a heat exchanger for the purpose of serving a domestic hot water line by obtaining heat from the water within the boiler.
The object of the invention is to improve the efficiency of the boiler in its domestic water heating capacity, and to that end, to provide such disposition of the parts that the boiler will have improved internal circulation.
Further objects and advantages will be apparent from the following description, taken in connection with the accompanying drawing, which illustrates a boiler casting assembly, Figs. 1, 2 and 3 being respectively front elevation, top and right side views.
With reference now to the drawing, in the assembly illustrated there are three sections, namely, front I, back 2, and intermediate sec tion 3 disposed therebetween, it being understood that, as is usual in the art, the assembly may include other sections located between the intermediate section and either the front or the back section, or both, so that a range of capacities is available in production. The sections shown are of cast iron, and of course hollow, as usual.
The front and back sections are provided in the bottom left corner with return inlets 4 and near the top with end outlets 5, and the intermediate section is provided with a top outlet 6 adjacent its right side. The sections are interconnected with communication between their cavities by the usual nipples I, located at the right side adjacent top and bottom, and at the left side adjacent the water line, as indicated in dotted lines, Fig. 1; wherein appears a mark 8, at the water line.
The front section I has an opening 9 and the other sections are correspondingly formed, as indicated in dotted lines at Fig. 3, to provide the usual combustion chamber, the boiler illustrated being adapted for gas fired operation.
As illustrated the sections appear slightly spaced apart in order to show the nipples l, but in practice the sections will be pulled tight together bytie rods located in recesses H, as will be well understood by one familiar with the art. Similarly, the castings are formed to provide flue passages I2 therebetween, bosses preventing flue gas egress except through those passages, a seat l3 at the top for a flue collector, insulation, jacket, gauge glass, etc. being added to the assembly before the boiler is complete.
According to this invention heat exchanger means for domestic water is disposed within the intermediate section, above the combustion chamber and just below the water line. heat exchanger here shown is in the form of a number of return-bend tubes I4 mounted on plate l5 which in turn covers an opening on the right side of the intermediate boiler section 3, the tubing extending from the plate to a position adjacent the far nipples i of the section. It will be appreciated that the size and nature of the heat exchanger I4 will depend upon the demands of the installation.
In operation, whenever there is no demand upon the heat exchanger 14, the contents of which therefore will be substantially at the temperature of the surrounding water in the boiler, circulation of the water will be substantially unaffected by. the heat exchanger, the latter, however, being located above the combustion chamber, where the boiler water is at maximum temperature. v
In steam service the rate of liberation will be maximum just above the heat exchanger and in hot water service there will be flow, at maximum temperature upwardly past the heat exchanger and from the boiler through the top outlet 6. In either event, on domestic hot water demand, flow through the heat exchanger will produce water instantly at maximum temperature, whether the heat exchanger be arranged to serve astorage tank or be connected directly to the domestic hot water system.
In summer operation, flow through the boiler to its radiators being cut off either by the usual suitable valves in a hot water installation, or by operation below steaming temperature, in a steam installation the heat exchanger still is at the location of maximum boiler water temperature. Under such condition internal circulation will generally be upwardly in the intermediate section and downwardly in the end sections during periods of no domestic water demand, and may be in the reverse direction when the heat exchanger output is maximum and the heat'exchanger is of sufficient capacity as to materially effect thermosyphonic flow.
Having thus described my invention, I claim:
In a sectional heating boiler including a pair of end sections and an intermediate section therebetween arranged to provide a combustion chamber with flue passages leading therefrom between said sections, means interconnecting said sections at one side adjacent the waterline and at the other side adjacent the top and the bottom, said end sections having cold water inlets adjacent the bottom at said first named side, and a domestic water heat exchanger disposed within said intermediate section above said combustion chamber and below the waterline, said intermediate section having, at said other side, a top outlet and mounting means for said heat exchanger,
