Abstract

437,482. Heating feedwater. BABCOCK & WILCOX, Ltd., Farringdon Street, London.-(Assignees of Lucke, C. E.; 110, Riverside Drive, New York, U.S.A.) Oct. 22, 1934, No. 30272. Convention date, Oct. 21, 1933. [Class 64 (i)] Water flows through an economizer 26 under normal operating conditions in counterflow to the furnace gases from the boiler 14, and during lay over periods or conditions of light load the water flow is reversed. When the feed valve 40 and a valve 31 between the economizer and the boiler drum are closed, a valve 42 is opened to allow water to circulate from the upper header 24 of the economizer through a downtake 46 to the lower header 28 and then upwards through the sinuous water tubes. Further connections with valves may be provided to allow reversal of water flow at light loads while the feed valve is open, and a pump may force water from the boiler drum upwards through the economizer during lay-over periods.
