Exhaust gas recirculation type combined plant

摘要

Widening a partial load operation range of an exhaust gas recovery type combined cycle plant in which a gas turbine and steam turbine are combined and further improving heat efficiency. Suppressing a temperature of internal gas in the compressor when recirculating gas turbine exhaust gas at partial load operation time and then returning to the compressor so as to increase exhaust gas recirculation amount. The partial load operation range can be widened and further the heat efficiency can be improved.
