Method for adapting the operating status of a stepped combustion chamber for gas turbines feeds an overall fuel mass flow rate into a combustion chamber through a control valve adapted to a defined operating point for a power mechanism.

摘要

An overall fuel mass flow rate (WF) metered through a control valve (6) and adapted to a defined operating point for a power mechanism is fed into a combustion chamber. A stepped valve (7) adjusts what proportion of the overall fuel mass flow rate is fed to pilot and main burners. An electronic power mechanism regulator (8) has first (8a) and second (8b) regulating blocks. The first block adjusts the control valve. The second block controls the stepped valve.
