OPERATING A GAS TURBINE WITH SUPPLEMENTAL COMPRESSED AIR

摘要

A method is provided to ensure that a combustion turbine (12) may operate at maximum power at elevated ambient temperature and/or low air density. The method includes a combustion turbine mode in which air is supplied exclusive ly from a combustion turbine compressor (14), a compressed air augmentation mod e in which additional air is supplied from an air storage (28), and an air storage charging mode in which air from a charging compressor (32) is suppli ed to the air storage (28). Alternatively, the air storage (28) may be eliminat ed and the charging compressor (32) sized for full supplemental air flow.
