ABSTRACT:
In a mixed gas turbine, wherein excessive steam in a plant is mixed with exhaust gas of a high-pressure turbine and then introduced to a low-pressure turbine, the present invention makes improvements such that even when a flow rate of the main flow in the high-pressure turbine is small, an efficiency may not be lowered. A final stage of a high-pressure turbine and a mixed-gas pressure adjusting stage are arrayed in opposition with an exhaust gas chamber of a high-pressure turbine casing placed therebetween, also a flow passage guide plate is provided within the exhaust gas chamber to rectify the flows of the exhaust gas in the final stage and the mixed-gas in the pressure adjusting stage and lead them to an exhaust gas port and a low-pressure turbine communication pipe by mixing their pressures.
