发明名称 EVAPORATOR FOR MULTIPLE EFFECT TYPE FRESH WATER GENERATOR
摘要 PROBLEM TO BE SOLVED: To prevent lowering of heat transferring performance caused by generation of dry spot and thickening of a liquid film on surfaces of heat transfer tubes to more than necessary, by holding the liquid film on the surfaces of the heat transfer tubes with a minimum necessary sea water flow rate. SOLUTION: This evaporator for a multiple effect-type fresh water generator comprises a heat transfer tube bundle 12 composed of the plurality of horizontal heat transfer tubes 21 arranged in multi-stage or multi-row. Arrangement pitches of the heat transfer tubes 21 of the row at a radial outer side of the heat transfer tube bundle 12 is non-dense in comparison with arrangement pitches 21 of the heat transfer tubes of the row at a radial inner side of the heat transfer tube bundle 12.
