David Cochrane was a Scottish-born American inventor known for developing the first open feed water heater. He also was the first to design a successful oil separator, among numerous other appliances related to steam generation.[1]
History and innovations
[edit]In his early years he worked as a pattern-maker on the Clyde. In 1879 he came to the United States, where he entered the employment of Ferris & Miles, but, shortly afterward went with the Harrison Safety Boiler Works, then the builders of a sectional cast-iron boiler. His open heater, brought out in 1883, was specifically designed to protect boilers from the effects of cold, unpurified feed water and was itself the first to be built of cast-iron plates, to avoid corrosion. Cochrane was also the first to design a successful oil separator, a heater and receiver, and other appliances. He was distinguished by great common-sense in engineering matters. He was frequently consulted concerning the design of steam plants, and his great contribution to steam engineering consisted in focusing attention upon the more efficient utilization of exhaust steam for heating buildings and for heating and purifying water to be used for feeding boilers and for industrial purposes. As early as 1894, he advocated the withdrawal of steam in course of expansion for feed heating and similar purposes.[1]
