The invention relates to a method for operating a gas turbine power plant, including a gas turbine, a HRSG following the gas turbine, an exhaust gas blower, and a carbon dioxide separation plant which separates the carbon dioxide contained in the exhaust gases and discharges it to a carbon dioxide outlet, the gas turbine, HRSG, exhaust gas blower, and carbon dioxide separation plant being connected by means of exhaust gas lines. According to the method a trip of the gas turbine power plant includes the steps of: stopping the fuel supply, switching off the exhaust gas blower, and controlling the opening angle of a VIGV at a position bigger or equal to a position required to keep a pressure in the exhaust gas lines between the HRSG and the exhaust gas blower above a minimum required pressure. The invention relates, further relates to a gas turbine power plant configured to carry out such a method.

A system for heating one or more components of a heat recovery steam generator that includes a heat-transferring conduit that fluidly connects a high-pressure section of a flow path to a low-pressure section of the flow path. The flow path is defined by a housing of the heat recovery steam generator and configured to direct a heat-containing medium. The heat-transferring conduit is configured to receive the heat-containing medium from the flow path such that the heat-containing medium flows through the heat-transferring conduit via a pressure differential between a first pressure of the heat-containing medium at the high-pressure section and a second pressure of the heat-containing medium at the low-pressure section. The heat-transferring conduit is further configured to heat the one or more components of the heat recovery steam generator via directing the heat-containing medium to be in heating contact with the one or more components.

An apparatus comprises a leading edge of an inlet. The leading edge of the inlet is positioned relative to a direction of air flow such that a total pressure of air along the leading edge of the inlet is equalized within selected tolerances.
