Abstract: PROBLEM TO BE SOLVED: To perform the transfer from a normal operation start-up drive state to a controlled load drive state without pressure drop by supplying heat inside the exhaust gas flow of a gas turbine to a flow-through regulator for feed water flow. SOLUTION: By a three-component control, a level regulator 13 changes the set value Sollein , using the flow-through regulator 14 for feed water flow, which is subordinated to a superordinated level regulator 13. The water level in a drum 6 is always regulated to the set value Soll, regardless of interfering effects. In this method, heat QAG in the exhaust gas flow of a gas turbine is supplied to the flow-through regulator 14 for feed water flow. With this, overall water level regulation is performed and the transition from the normal operation start-up drive state to the controlled load drive state can be performed without pressure drop and without changing the structure of a regulation cycle.
