Abstract
The invention relates to a method for inter alia to increase the energy and cost efficiency of a gas power plant or a thermal heat plant with COcapturing. The power plant comprises gas turbine plants (') comprising compressor units (′) and turbine units (′) and further comprises a combustor (). The combustor () is working in principle with to separate gas part streams where one gas part stream flows internally through the flame tube () of the combustor (), while the other gas part stream is flowing along the exterior of the flame tube (). The first gas part stream comprises additional air and re-circulated, un-cleaned flue gas from the combustor (), said gases being combusted together with fuel inside the flame tube (). The second gas part stream comprises cleaned flue gas which is heated up at the exterior of the flame tube () while the flame tube () is cooled down. The invention comprises also a power plant, a combustor and a COcapture plant.
