PURPOSE:To promote the thermal efficiency and reduce the fuel consumption by loading a pair of gas turbines and introducing exhaust gas from a gas turbine of each plant to each exhaust gas boiler for supplying the vapor obtained here to a vapor turbine driven by a propeller on the other side of the plants. CONSTITUTION:A pair of propulsion plants 20 and 21 are provided to drive propeller shafts 8 and 9 on both sides of a vessel and gas turbines 22 and 23 are respectively provided with exhaust gas boilers 24 and 25. The vapor obtained by heat transfer pipes 26 and 27 of respective gas boilers 24 and 25 is supplied to a vapour turbine 30 and 31 provided on reduction units 29 and 28 driven by gas turbines 23 and 22 of the other plants 21 and 20 via vapor supply pipes 32 and 33. The vapor passing through vapor turbines 30 and 31 is returned to the exhaust gas boilers 25 and 24 of the original propulsion plants 21 and 20 via steam-condensers 34 and 33, feed water pumps 38 and 39, and feed water pipes 41 and 40. |
