Turbine equipment and combined cycle power generation equipment and turbine operating method

摘要

Turbine equipment with a TCA cooler (12), comprising a gas turbine (4) having a compressor (1), a combustor (2), and a turbine (3), the TCA cooler (12) for cooling fluid partly extracted from compressed air from the compressor (1) by leading the fluid therein and performing a heat exchange and leading the cooled fluid to the turbine (3) side of the gas turbine (4), and a temperature control means (15) for controlling the fluid on the outlet side of the TCA cooler (12) to a dew-point temperature or higher, whereby the dew condensation of moisture and vapor on the outlet side of the TCA cooler (12) can be eliminated, and the overcooling of the fluid partly extracted from the compressed air can be eliminated.
