Cochrane Heaters For Condensing Plants If you are going to run your plant condensingthere are several important reasons why youshould use a Cochrane Open Feed-Water Heater,operating the pumps and smallengines non-condensing, and usingthe exhaust steam from theseengines to heat the water in theCochrane Heater. Since a condensing engine hasan efficiency of less than 15%, theauxiliaries, if they are run off themain engine, will have the sameefficiency minus transmissionlosses; but if these auxiliaries are run non-con-densing all the heat in the steam supplied to theauxiliaries which is not utilized in doing workcan be conserved in the heater, giving the aux-iliaries an efficiency of practically 100%—insteadof less than 15%. Then there is the higher vacuum you can ob-tain by having a Cochrane Open Heater to driveoff the air and gases from the feed-water—alsothe independence of the auxiliaries from themain engine, etc. The new steam turbine plantsare being equipped with open heaters—
