Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To definitely maintain the temperature of evaporation gas supplied to a duplicate gas engine within an allowable range.SOLUTION: A marine vessel comprises: a gas feed line between a tank and a compressor; a first supply line between the compressor and a main gas engine; a liquid feed line between a pump in the tank and a forced carburetor; a second supply line between the forced carburetor and the duplicate gas engine; a return line for returning excess gas to the tank from the first supply line; a heat exchanger for heat exchange between the evaporation gas and the excess gas; and a control device in that while controlling an adjusting valve for changing the flow rate ratio of the evaporation gas passing through a heater provided in the second supply line and the evaporation gas passing through a bypass line so that the evaporation gas temperature becomes a target temperature by feedback control, while the flow rate of the excess gas flowing through the return line increases or decreases, that controls the flow rate of the evaporation gas passing through the bypass line or the flow rate of the evaporation gas passing through the heater so as to increase prior to the feedback control.SELECTED DRAWING: Figure 1
