PROBLEM TO BE SOLVED: To provide an evaporator for liquefied gas capable of restricting reduction in durability upon power failure and appropriately performing an energization upon power return.SOLUTION: An outlet side flowing degree adjustment part B comprises: an outlet side flow rate adjustment valve 5 arranged at a heat source liquid discharging passage 4 capable of freely adjusting a degree of opening and capable of being changed over to a closed state; and an outlet side bypass discharging passage 8 arranged under a form in which it branches from a location at a more upstream side than that of the outlet side flow rate adjustment valve 5 at the heat source liquid discharging passage 4 and bypasses the outlet side flow rate adjustment valve 5 under a state in which there is provided a rising-up part 8t rising more upwardly than the heat source liquid height when the heat source liquid SW is fully filled in a vaporizer E for liquefied gas, and a passing flow opening degree is lower than that of the heat source liquid discharging passage 4. The outlet side flow rate adjustment valve 5 is constituted to be changed over to its closed state upon power failure.SELECTED DRAWING: Figure 1 |
