Title:
GASIFICATION DEVICE FOR LOW-TEMPERATURE LIQUEFIED GAS
Document Type and Number:
WIPO Patent Application WO/2012/120580
Kind Code:
A1
Abstract:
Provided is a gasification device for low-temperature liquefied gas for which curvature of the inter-gasification-pipe distribution pipes caused by changes in the temperature of the inter-gasification-pipe distribution pipes in the lengthwise direction does not easily occur. This gasification device has multiple gasification pipes (21), and inter-gasification-pipe distribution pipes (22) that distribute a low-temperature liquefied gas to these gasification pipes (21), and is characterized by being equipped with: gasification pipe panels (16), for which multiple gasification pipes (21) are aligned in the horizontal direction in a vertical plane, and inter-gasification-pipe distribution pipes (22) extend in the horizontal direction and are connected to the lower ends of each of the gasification pipes (21); a liquid supply unit (30) that supplies a heat exchange-use liquid from the upper ends of the gasification pipe panels (16) such that the liquid flows down along the multiple gasification pipes (21); and heat transfer reduction units (23) for the purpose of reducing, with respect to the heat transfer rate from the heat exchange-use liquid in a first region (A1) of the inter-gasification-pipe distribution pipes (22) on which the multiple gasification pipes (21) are arranged, the overall heat transfer rate from the heat exchange-use liquid in a second region (A2) of the inter-gasification-pipe distribution pipes (22) that is outside of the first region (A1).
