Projects of the Combined Cycle Steam and Gas Units (Combined Cycle Power Plants - CCPP) reveal a high efficiency when being applicated to reduce the air pollution caused by ash, SO and NO emissions. It was proven out by operation. Used to reduce CO2 emissions, these units allow the obtaining of even better results. (This application will be of great importance in future.) ＇＇Freezing out＇＇ and alkanolamyn CO2 disposal methods require a 1.3 - 1.4 times increased proportional fuel consumption. CO2 ＇＇freezing out＇＇ in the CCPP cycle with intermediate gas cooling to to = 170 K partially equilibrates the capacity decrease of GTUs at the expense of the increase of the stream turbines＇ capacity. In Russia, a considerable practical experience in this type of CO2 is being extracted in crystals at experimental plants from flue gas behind the expansion turbine. Regenerating units cooling gas under pressure (p = 0.4 MPa) to to = 173 K before the expansion turbine were elaborated and tested in the refrigeration industry. Given here are thermal diagrams, characteristics of demonstration gas turbine and steam-gas plants with CO2 disposal, equipment scheme and general project parameters for long-range CCPP. The efficiency of these CCPP will be 20% higher than that of modern pulverized-fuel blocks without CO2 disposal.
