The waste heat steam generator employs two parallel channels for receiving flows of exhaust gas from a gas turbine. In one channel, the exhaust gas flow is heated by a supplemental burner to a temperature less than 900 DEG C while the flow of exhaust gas in the second channel is heated to a temperature above 900 DEG C. The amount of fuel supplied to each burner is controlled by various control means responsive to the temperature within the steam generator or the temperature of the live steam or by the pressure of the live steam. A distribution means is provided at the entrance to the channel in which the exhaust gas is heated to a temperature above 900 DEG C so as to control the flow therein. The steam generator can be easily adapted to partial load operation by regulating the amount of fuel to the supplemental burners.
