VAPORIZER FOR LNG REGASIFICATION CARRIER

摘要

A vaporizer for an LNG regasification ship is provided to simply and economically detect whether gas is contained in heat exchange water used for regasification of LNG gas. A vaporizer for an LNG regasification ship includes a heat exchanging pipe(142) and a gas detection apparatus(200). The heat exchanging pipe passes through the interior of the vaporizer, and heat exchanging water having a heat source of the LNG gas flows through the interior of the heat exchanging pipe. The gas detection unit is installed on one side of the heat exchanging pipe to detect whether gas is contained in the heat exchanging water. The gas detection apparatus includes a liquid sampling unit(210), a gas extracting unit, and a gas detecting unit(240). The liquid sampling unit samples some of the heat exchanging water through a branch pipe passage. The gas extracting unit extracts only the gas contained in the heat exchanging water. The gas detecting unit detects the extracted gas and detects whether gas is contained in the heat exchanging unit.
