- 船体又は陸上設備に設けられたガス放出システムであって、
液体水素を貯留するタンクと、
上方へと延びる放出塔であって、その少なくとも上端部に、大気に開口した放出口が設けられた内管、及び前記内管との間に隙間をあけて前記内管の周りを覆う外管からなる二重管構造を有する放出塔と、
前記タンク内で前記液体水素が気化した蒸発ガスを前記内管内に導く放出ラインと、
前記内管と前記外管の間の前記隙間に、酸素の沸点より高い温度の水素ガス又はヘリウムガスである媒介ガスを供給するガス供給装置と、を備える、ガス放出システム。 - 前記放出塔は、前記放出口から前記蒸発ガスが放出される方向と同方向に前記媒介ガスを放出するように、前記放出口の周りで前記内管と前記外管の間の前記隙間を大気に開口するように構成された、請求項1に記載のガス放出システム。
- 前記ガス供給装置は、加熱器と、前記タンクから前記加熱器に前記蒸発ガス又は前記液体水素を供給する第1供給ラインと、前記加熱器から前記内管と前記外管の間の前記隙間に前記媒介ガスを供給する第2供給ラインと、を備える、請求項1又は2に記載のガス放出システム。
- 前記放出ラインに設けられた開閉弁を備え、
前記ガス供給装置は、前記タンク内の圧力が第1設定圧を超えた場合に、前記媒介ガスの供給を開始し、前記開閉弁は、前記タンク内の圧力が、前記第1設定圧より高い第2設定圧以下である場合に閉じており、前記タンク内の圧力が前記第2設定圧を超えた場合に開く、請求項1〜3のいずれか1項に記載のガス放出システム。
