|} Superheat—A Proven Fact The superheating of steam was early recognized as very desirable as a means of increasing efficiency while decreasing operating costs. But it took many years to produce a reliable superheater. Today, there are over 3,000 ships, flying all flags, equipped with Elesco Type fire-tube superheaters, which type has proven to be the one that satisfies all requirements. The use of high degree superheat effects a saving in coal and water and also increases the capacity of the boiler and the efficiency of the engine or turbine. Efficiency of the boiler is still further improved by reason of the additional heating surface introduced by the superheater. Elesco fire tube superheaters are adaptable to either new or existing boilers, requiring no change in design or construction. ‘Their construction provides easy access to all screwed joints, easy removal of parts and permits thorough cleaning of tubes when required. The units do not retard gases more than retarders. In fact, the superheater in no way interferes with the normal operation and functioning of the boiler. Its ruggedness assures an absence of failures. You cannot compete with the more efficient ships with- out superheaters. Have you the facts?
