A LaMont boiler is a type of forced circulation water-tube boiler in which the boiler water is circulated through an external pump through long closely spaced tubes of small diameter. The mechanical pump is employed to in order to have an adequate and positive circulation in steam and hot water boilers. ==History== Mark Benson himself in the year 1856 worked on the idea and later Benson worked with Herreshoff on the idea of parallel flow forced circulation non-drum boilers. Later, Walter Douglas Lamont brought the idea from papers to existence.Walter Douglas La Mont introduced the concept of this forced circulation boiler in the year 1925. Lamont was a Navy Lieutenant Commander and an engineer in the US marines as well as a patriot. He died of a sudden and very early death and the headlines of the Niagara Falls Gazette mentioned ''NAVAL ENGINEER,NATIVE OF CITY IS HEART VICTIM''. The initial designs of Lamont for this boiler confirmed the lighter, safer and higher rates of heat transfer and evaporation per square foot as compared to that of the standard water tube boilers, also the circulation of vaporized water at a differential pressure of 2.5 bar was 8 to 10 times . The time duration needed for starting a Lamont Boiler to be able to deliver an evaporation rate of 100,000 pounds per hour was between 15 to 20 mins and simultaneously was able to deliver peak loads. During the World War II the U.S navy used and relied mainly upon the Babcock and Wilcox boilers which were used commonly in those years. On the other hand, thousands were built in Europe and many German and Japanese ships used La mont boiler, Bismark was one among them and they were able to outrun the fastest steamers from the US Navy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LaMont boiler」の詳細全文を読む スポンサード リンク
