SEAWATER HEATING DEVICE AND AN LNG REGASIFICATION SYSTEM USING THE SAME CAPABLE OF SUPPLYING TEMPERATURE-ELEVATED SEAWATER TO AN LNG REGASIFICATION SYSTEM

摘要

PURPOSE: A seawater heating device and an LNG regasification system using the same are provided to effectively regasify LNG using a small quantity of seawater by supplying seawater to an LNG regasification system after elevating the temperature of seawater with the waste heat of an engine room cooling system.;CONSTITUTION: A seawater heating device(100) comprises an engine room cooling system(110), a buffer tank(120), and a supply valve(130). The engine room cooling system discharges temperature-elevated first seawater with using the waste heat generated when cooling an engine room. The buffer tank loads the discharged first seawater. In order to supply third seawater, of which temperature is increased by mixing the first seawater with second seawater supplied to an LNG regasification system(200), to the LNG regasification system, the supply valve is installed on a discharge line between the buffer tank and a seawater supply line to control the quantity of the first seawater.;COPYRIGHT KIPO 2013
