Description
図1は、本発明の一実施形態である液化ガス燃料船の燃料供給システムの構成を示すブロック図である。
Z=A・X+B・Y (1)
S≧(混合燃料硫黄分質量)/(混合燃料全質量)
≧(S1・X+S2・Y)/(X+Y) (2)
X≦Z・(S−S2)/(B・(S1−S)+A・(S−S2)) (3)
Y≧Z・(S1−S)/(B・(S1−S)+A・(S−S2)) (4)
となる。
X:Y=S−S2:S1−S
となる。また、このときに必要な燃料油と液化ガス燃料の容積比V1:V2は、
V1:V2=((S−S2)/γ1):((S1−S)/γ2) (5)
となる。ここでγ1は燃料油の比重、γ2は液化ガス燃料の比重である。
燃料油タンクと液化ガス燃料タンクの容積比を(5)式にすると、両タンク容積は、両燃料にとって過不足のない最適な割合となる。
