STAR FIN TYPE HEAT TRANSFER TUBE IN OPEN RACK TYPE LIQUIFIED NATURAL GAS VAPORIZER

摘要

PURPOSE: To provide an open rack type liquefied natural gas vaporizer, capable of filling the interior of a lower header with LNG even when the load is small, requiring a small heat input without causing a fluctuation in heat quantity by forming the caliber of the lower header into a smaller one than that of an upper caliber. ;CONSTITUTION: This open rack type natural gas vaporizer is obtained by forming the caliber of a lower header 1 into a smaller one than that of an upper header 4. Furthermore, the ratio of the surface area of the lower header 1 to the LNG flow rate is preferably set at ≤0.4 at the maximum.;COPYRIGHT: (C)1996,JPO
