Abstract

12,712. Junkers, H. June 3. Heating water.-Relates to apparatus for, and a method of, heating water. The supply of heat takes place continuously, and the rate of supply is governed by a suitable temperature regulator. Low-pressure and highpiessure apparatus o f various forms are d e - scribed in the Specification. Figs. 1, 4, and 9 show forms of heaters embodying the features of the invention, and Fig. 12 shows the construction and arrangement of means for supplying water at temperatures between hot and cold. In the gas-heated lowpressure apparatus shown in Fig. 1, cold water is supplied from the pipe a through the distributer c to the reservoir d, and hot water is drawn from the delivery pipe e. The cap i of the gas regulator is exposed to the water in the lower part of the vessel d. Around the heater g the circulation casing k is arranged, and surrounding the reservoir d is the insulating-casing l. The eduction pipe B is interrupted as shown at A. The apparatus may be heated by steam, hot water, or the like. In the high-pressure apparatus shown in Fig. 4, the supply pipe is connected to the receptacle d without the intervention of the shut-off cock b. The water from the supply pipe flows through a water vessel or through a check valve o and air vessel p to the distributer c, to allow for the expansion of the water during heating. In another form of apparatus, the water of expansion is allowed for by a combination of a check valve and a relief valve arranged in the water-supply pipe. In the highpressure apparatus shown in Fig. 9, the heating- coils B<1> are supplied with heated liquid from the external apparatus a, the open vessel E is arranged on a stand-pipe and allows for expansion in the circulating-medium, and the eduction pipe B is interrupted at A. The valves 2, 9, Fig. 12, are arranged as shown in relation with the draw-off pipe 1, and with the cold and hot water supply pipes 3, 7. Boiling water or superheated water may be withdrawn from the apparatus by the use of a loaded automatic delivery valve, or by a stand-pipe.
