Description
フィン付き管内の上部に、液化ガスが気化して生成した気化ガスの流れに抵抗を付与する絞りが設けられており、絞りの上端が、フィン付き管の上端よりも下方に位置している空温式液化ガス気化器。
図1〜図4に示す態様で、各蒸発ユニット(3)のフィン付き管(6)の数を7本、蒸発ユニット(3)の数を5、各フィン付き管(6)の長さを6mとした空温式液化ガス気化器(1)を使用し、各フィン付き管(6)内の流量が13.5〜20kgとなるように液化天然ガスを液化ガス入口管(8)から供給して、気化ガスを得た。そして、全フィン付き管(6)のうち適当な位置にある複数のフィン付き管(6)の上端部の温度の経時変化を測定した。その結果を図5に示す。
フィン付き管に絞りが設けられていないことを除いては、上記実験例と同じ構成の従来の空温式液化ガス気化器を使用し、各フィン付き管内の流量が13.5〜20kgとなるように液化天然ガスを液化ガス入口管から供給して、気化ガスを得た。そして、全フィン付き管のうち適当な位置にあるフィン付き管の上端部の温度の経時変化を測定した。その結果を図6に示す。
