Gas turbine power plant with a gas turbine assembly and method for operating a gas turbine power plant

摘要

The station (1) has a gas turbine system (2) provided with a compressor (3) and two gas turbines (4, 5), where the compressor and one of the gas turbines are decoupled from each other. The compressor is driven by the other turbine. A blower (9) is coupled with the former gas turbine. A heat source heats the blower air (20), where the former gas turbine is supplied with heated blower air by the heat source in a standby mode of the former gas turbine. The gas compressed by the compressor of the gas turbine system is saturated with water at a saturation device. The heat source is a burner e.g. natural gas burner, coal-derived-gas burner, diesel oil burner or methanol burner, or an oven i.e. oil-operated or gas-operated oven. The water is a tap water. An independent claim is also included for a method for operating a gas-turbine electric power station.
