摘要： Providing an exhaust gas energy recovery device by which the optimal engine operating condition can be continuously maintained in a manner that the flow rate of the engine exhaust gas fed to the power turbine is regulated so that the scavenging air pressure becomes optimal in order that the engine performance (the fuel consumption rate) corresponding to the engine load and the engine speed becomes optima. The engine exhaust gas energy recovery device provided the engine load detecting sensor, the engine speed detecting sensor and the scavenging air pressure detecting sensor, the device regulating the flow rate of the exhaust gas streaming into the exhaust gas turbocharger via controlling the flow rate of the exhaust gas streaming into the power turbine of the exhaust gas energy recovery device, so that the scavenging air pressure is maintained at an arbitrarily ordered level and the engine is operated under a condition that the fuel consumption rate is minimal.

摘要： [Problem] To provide a control method and device for a turbine generator, which can reduce generated power without wasting fuel consumption of a diesel engine when the demand power decreases and thereby the generated power is brought into an excess state. [Solution] A turbine generator configured by joining a power turbine (7) which is driven with exhaust energy of exhaust gas emitted from a diesel engine (3) as a power source and a steam turbine (9) in series, wherein the diesel engine (3) is provided with an exhaust turbosupercharger (5), extracts part of exhaust gas before the exhaust gas is supplied to the exhaust turbosupercharger (5), supplies the extracted exhaust gas to the power turbine (7) after adjusting the supply amount thereof, supplies steam generated by an economizer (11) to the steam turbine (9) after adjusting the supply amount thereof, and when the demand power decreases and thereby the generated power is brought into an excess state, decreases the supply amount of the exhaust gas to the power turbine (7) to minimize the output of the power turbine (7), and thereafter decreases the supply amount of the steam to the steam turbine (9).
