Combined-cycle power plant with control of the inlet air temperature and method for controlling a combined-cycle power plant

摘要

A kind of combined-cycle power plant includes: gas turbine assemblies (2), the suction inlet airflow (QI) with air intake (18); Ancillary equipment (10); A kind of closed cooling circuit (11) is used for auxiliary cooling device (10); With air-intake heating mechanism (12), heating inlet airflow (QI) can be operated and be aspirated through air inlet (18); Wherein air-intake heating mechanism (12) includes heat exchanger (28), along air inlet (18), to be hit by inlet airflow (QI) and be configured with to allow the closed cooling circuit (11) of heat exchange between working fluid to be aspirated through air inlet (18) with inlet airflow (QI).
