Turbo-alternator plant

In a turbo-alternator plant comprising a prime mover producing hot exhaust gases, a waste heat boiler connected to receive the exhaust gases from the prime mover and thereby generating steam, a turbine receiving the steam to be driven thereby, an alternator, each of said turbine and said alternator having a rotor, the rotors being drivingly connected, and a steam condenser connected to receive steam exhausting from the turbine;

• the improvement, wherein the turbine rotor and alternator rotor are directly connected together and are disposed with the rotational axis of the said rotors vertical, the alternator being above the turbine and wherein there is a bearing arrangement supporting the said rotors including a bearing supporting the weight of their rotors, said bearing being within the environment of said condenser receiving steam exhausting from the turbine, and there being means governing the rotor composite to a speed appropriate to the desired frequency of the alternator output.
