PURPOSE:To aim at increasing the output power of a turbo-generator and simplifying the arrangement of an exhaust gas heat recovering device, by feeding low pressure steam from a low pressure steam separating drum into a mixed-pressure turbine, and by supplying feed water and saturated water in the steam separating drum into an exhaust gas economizer. CONSTITUTION:Superheated steam from a superheating section 13 in an exhaust gas economizer 1 is fed into the high pressure side of a mixed turbine 30. Low pressure steam separated from a low pressure steam separating drum 5 is led into the low pressure side of the mixed-pressure turbine 30. Feed water (gf) from a drain tank 26 and saturated water (gr) from the low pressure steam separating drum are introduced into a mixing pipe 32, and are then fed into a preheating section 11 in the exhaust gas economizer 1. With this arrangement it is possible to aim at increasing the output power of a turbo-generator and simplifying the arrangement of the exhaust gas heat recovering device. |
