Abstract
171,966. L'Auxiliaire des Chemins de Fer et de l'Industrie. Nov. 23, 1920, [Convention date]. Feed-water, supplying.-Feed-water is supplied to a heater 2 by a pump 4 in tandem with the pump 5 that withdraws the water'from the heater and forces it into the boiler, an open expansion vessel 3 being connected to the top of the heater and to the feed tank or to the supply pipe 9 to ensure sufficient pressure for the working of the pump 5 and to provide for overflow from the heater. The pump supplying water to the heater is of greater capacity than the pump withdrawing water. The pipe 10 connecting the expansion vessel with the supply pipe is flared at its connection with the vessel. The water may be heated by exhaust steam.
