Abstract
267,450. Blunt, E. H. Aug. 31, 1925. Drawings to Specification. Feedwater, heating.-A feed-heating and supplying apparatus comprises a heater vessel, a pump handling hot and cold water on the two sides of the piston and means whereby a rise or fall in the pressure in the heater controls the output from the heater accordingly. The heater may be of the open or closed type and the use of a single or double cylinder pump is mentioned. The following features are incorporated in the example given, the description and application being the same as set forth in Specification 266,953 :-Control by the pressure in the heater (1) of the supply of additional heating steam from the exhaust of auxiliary engines, (2) of a frictional resistance in the cold-water supply from pump to heater so as to regulate the speed of the pump, and (3) of the main live-steam supply to the pump cylinders. Control by a float in the heater (1) of the resistance in the cold water supply to the heater to slow down the pump at an undue low water level, and (2) of a by-pass enabling cold water to return to suction or other pumping chamber of the pump; a hand-controlled by-pass permitting hot water to return to heater or to suction of other pump; a high-pressure relief valve on heater opening into a steam cylinder-jacket of pump.
