Abstract
Description
<主機燃費>
I.S.O.条件(機関室温度:25℃、冷却水温度:25℃)における主機燃費率をベースとし、外気温(=吸気温度)の変化を主機燃費率に考慮し主機燃費として算出した。
<ボイラ燃費>
主機負荷:C.S.O.(常用航海速力)、機関室温度:25℃における主機の排ガス量・温度からボイラを選定した。船内必要蒸気量は常用航海中(主機負荷C.S.O.)かつ冬場の温度条件(外気温:2℃、海水:5℃、機関室温度:25℃)で算出した。
外気温をグラフに記載の温度とした場合の主機排ガス量・温度に対し、選定したボイラから得られる蒸気量を確認し、船内必要蒸気量に対しての不足分を算出し追い焚きによる燃費悪化分として計上してグラフを作成した。
