SEA WATER HEATING SYSTEM OF LNG EVAPORATION SHIP

摘要

PURPOSE: An overheated steam is passed through a pressure lowering valve and a temperature lowering valve to an evaporator to obtain a desired steam of a sea water. CONSTITUTION: In an LNG evaporation ship propelled by a propelling turbine and a steam generator, a steam boiler(2) is connected to a heat supply portion of a heat exchanger(16). A sea water supply device(14) is connected to a heat absorbing portion of the heat exchanger. A discharge port of the heat absorbing portion is connected to an evaporator(13). A pressure lowering valve(11) and a temperature reducing valve(12) are installed between the steam boiler and the heat exchanger.
