Abstract

14,989. T÷belmann, C. July 4. Water-circulation, promoting; auxiliary boilers; feedwater, supplying &c.-To increase the circulation in boilers and in installations for heating by hot water and other liquids, steam at a relativelyhigh pressure is generated by the arrangement used for heating the water or liquid and is discharged into the heating-circuit. Fig. 1 shows the arrangement as applied to one form of watertube boiler and Fig. 3 to a hot-water heating- installation. As regards Fig. 1, the small watertube boiler 8, situated immediately over the furnace, is provided for the supply of steam by the pipe 11 and mouth 5 to the extension 6 of the front header 2. The steam supply may be cut off from the pipe 11 by the valves 12 or 13. The water dripping from the steam pipe 32 may be caught by the pan for feeding the auxiliary boiler, or pure water alone may be used. The supply is made up by the float 28 opening the valve 27 in the pan. The gauge glass 14 may be provided. In the arrangement shown in Fig. 3, the steam is injected into the widened portion of a vertical pipe. The injector could be equally well arranged in the discharge pipe.
