A steam gas plant including a gas turbine the exhaust gases of the gas turbine feed the burners of the steam generator which in turn feeds the steam turbine, a steam generator, and a steam turbine, in which the operation of the gas turbine continues under full load even for reduced loads on the steam turbine. The invention maintains under varying steam turbine loads the temperature at the input of a deaerator constant, the deaerator being fed in parallel by an economizer subjected to the heat of the flue gases of the steam generator and by water heaters fed with steam extracted from the turbine. To ensure constant temperature, one of the streams feeding the deaerator is controlled by a gate the extent of opening of which is defined by the ratio of the throughput of flue gases acting on the economizer and the flow of water in the economizer and possibly also by the modifications in the temperature at the output of the economizer.
