GAS TURBINE POWER PLANT WITH CARBON DIOXIDE SEPARATION

摘要

The invention relates to a gas turbine power plant, having a gas turbine, a waste heat steam generator following the gas turbine, an exhaust gas recooler, an exhaust gas blower, a carbon dioxide separation plant which separates the carbon dioxide contained in the exhaust gases from these and discharges it to a carbon dioxide outlet. A bypass chimney is arranged in the gas turbine power plant between the outlet of the waste heat steam generator and the exhaust gas blower and is connected to a fail-safe open connection both in the throughflow direction from the exhaust gas line to the bypass chimney and in the throughflow direction from the bypass chimney to the exhaust gas line. The invention relates, further, to a method for operating a gas turbine power plant of this type, in which the exhaust gas blower is regulated.
