Apparatus for recovering heat from the exhaust gases of marine prime movers is described comprising a feed water line and an exhaust gas economizer for effecting heat exchange between the exhaust gases discharged from the prime mover and feed water supplied from a feed water tank; said exhaust gas economizer having a high pressure steam generator section for receiving high pressure feed water and generating high pressure steam for use in driving a steam turbine, and a low pressure steam generator section for receiving low pressure feed water for generating general purpose steam for use for purposes other than driving said stream turbine; a pressure regulator device connected between said feed water line and said low and high pressure steam generator sections for regulating the pressure of said feed water to provide relatively low pressure and high pressure feed water to the repsective steam generator sections; a low pressure steam generator section for separating water from said general purpose steam; and a primary feed water preheater in said feed water line and connected to said low pressure steam separator device for mixing the water separated from said general purpose steam by said low pressure steam separator device and the feed water supplied to said exhaust gas economizer and thereby preheating said feed water.
