An operating method of a vessel and an internal-combustion engine system provided with an internal-combustion engine system and this

Japanese Patent JP5976498

B2

Provided is an internal combustion engine system that, when performing the actions of stopping and starting power generation in a supercharger for generating power, can avoid sudden fluctuations in the amount of steam produced by an exhaust gas boiler to stably operate a steam turbine and a steam turbine power generator. A water supply control valve (27) is controlled in an opening direction when the water level in a brackish water separator (12) falls below an allowable water level range and is controlled in a closing direction when the water level exceeds the allowable water level range. A steam inlet control valve (22) is controlled so as to supplement the amount of power generated by a steam turbine power generator (40) in accordance with variation in the amount of power generated by a power generator (3c) of a supercharger (3). The allowable water level range of the brackish water separator (12) is expanded when a supercharger power generation stop action is performed for stopping power generation by the power generator (3c) of the supercharger (3), and/or when a supercharger power generation start action is performed for starting the power generation by power generator (3c) of the supercharger (3).
