Abstract
Abstract A gas turbine power plant may consist of a gas producer, a main power turbine utilized for driving a load, a swell as an auxiliary turbine fed by the same gas producer as the main power turbine and utilized for some auxiliary purpose. In many installations the required output from the main power turbine, as well as from the auxiliary turbine may vary considerably from time to time. These varying working conditions will of course influence the requirements of output from the gas producer. In order to meet these varying conditions, power transfer means are arranged between the two turbines, as well as between any or both of said turbines, and the gas producer in such a manner that the output from the power-producing components may be utilized in the best way depending on the occasional load imposed on the plant. To facilitate the governing of the plant the main power turbine and the auxiliary turbine each have a rotor arranged in parallel gas passages from the gas producer, and at least one of said turbines is provided with means for governing the gas supply therefrom.

Claim 4
Dependent Claim
58 words
The gas turbine power plant according to claim 1 in which the main power turbine is provided with an output shaft, the auxiliary turbine being permanently connected to the output shaft of the main power turbine by a power transfer means including a freewheel, and to the gas producer means by power transfer means including a disengageable clutch.
Claim 5
Dependent Claim
85 words
The gas turbine power plant according to claim 1 in which said main and auxiliary turbines each is provided with an output shaft, the output shafts of the main and the auxiliary turbines, as well as the gas producer means being interconnected by a power transferring gear train, the main power turbine being connected to said gear train by an infinitely variable power transfer mechanism, and the auxiliary turbine and the gas producer means each being connected to said gear train by a disengageable clutch.
Claim 6
Dependent Claim
