Stable-pressure Steam Blowing-out Method for a Combined Cycle Power Plant

The aim, principle and acceptance criteria of steam blowing-out during the erection and commissioning test stage of a power plant are described along with a brief account of the commonly used pressure-reduction and stable-pressure blowing-out method. A detailed discussion is conducted of the specific features of a combined cycle power plant and the stable-pressure steam blowing-out. It is noted that the stable-pressure blowing-out method is more suitable for use in a combined cycle power plant. Meanwhile, some specific cases of employing stable-pressure blowing-out method in power plant engiineering are presented.
