To provide an engine room air supply system capable of improving total fuel consumption of a main engine and a boiler when an outside air temperature decreases in a vessel including the main engine directly sucking air from outside of the vessel and the boiler generating steam by using exhaust heat of the main engine and a burner.SOLUTION: An engine room air supply system for a vessel having a main engine 10 and a boiler 20 generating steam by using exhaust heat of the main engine 10 and a burner 25 includes: a vessel outer air supply port 5 for taking in air 6 from outside of the vessel; an air supply path 50 for directly supplying the air 6 taken in from the vessel outer air supply port 5 to the main engine 10; an engine room inner air supply port 8 provided in the air supply path 50 to take in air 9 from inside of the engine room; adjustment means 30 adjusting a mixing ratio between the air 6 from outside of the vessel and the air 9 from inside of the engine room; and control means 40 controlling the adjustment means 30 so as to improve total fuel consumption of fuel consumption of the main engine 10 and fuel consumption of the boiler 20.SELECTED DRAWING: Figure 2

    【課題】船外から直接空気を吸引する主機関と、主機関の排熱及びバーナーにより蒸気を生成するボイラとを備えた船舶において、外気温低下時の主機関とボイラとの合算の燃費を改善することのできる機関室給気システムを提供する。【解決手段】主機関10と、主機関10の排熱及びバーナー25により蒸気を生成するボイラ20とを備えた船舶の機関室給気システムであって、船外からの空気6を取り入れるための船外給気口5と、船外給気口5から取り入れた空気6を主機関10に直接供給するための給気経路50と、給気経路50に設けられた機関室内からの空気9を取り入れるための機関室内給気口8と、船外からの空気6と機関室内からの空気9との混合割合を調整する調整手段30と、主機関10の燃費とボイラ20の燃費とを合算した燃費が向上するように調整手段30を制御する制御手段40とを有する。【選択図】図2
