Abstract
【解決手段】熱交換パネル1の両面に沿って熱媒体(海水、循環水)を流下させることによりパネルを構成する伝熱管内を通過する低温流体(LNG、LPG、エチレンガス、LPガス等)を加熱し、または気化させる装置であって、ヘッダー4a、4bの入口側および/またはマニホールド6a、6bの入口手前に、調節弁11a、11b、12a、12bが取り付けられている。さらに、熱媒体を流下させるトラフに調節弁が取り付けられていることが望ましい。運転に際しては、低温流体の供給量の変動に応じて、一部のパネルへの液化ガスの供給を停止するとともに、残りのパネルでは定常負荷時における流量が維持されるように調節弁を操作する。
