コンバインドサイクル発電プラント

Japanese Patent JP7153498

B2

Provided is a combined cycle power plant configured so that the time until vapor is produced by the low-pressure heat exchanger of a waste heat recovery boiler can be reduced. This combined cycle power plant is provided with: a waste heat recovery boiler having a high-pressure heat exchanger which produces vapor having a first pressure, the waste heat recovery boiler also having a low-pressure heat exchanger which produces vapor having a second pressure lower than the first pressure and which is disposed downstream of the high-pressure heat exchanger; first gas extraction piping having one end which is connected to the gas extraction port of a compressor, and having the other end disposed within the waste heat recovery boiler in a region between the high-pressure heat exchanger and the low-pressure heat exchanger; a first flow rate regulation valve provided in the first gas extraction piping; a second gas extraction piping having one end which is connected to the discharge port of the compressor, and having the other end connected to the first gas extraction piping; a second flow rate regulation valve provided in the second gas extraction piping; and a control device for setting the first flow rate regulation valve or the second flow rate regulation valve to an open state when starting the gas turbine.
