Abstract
A method for influencing and monitoring the oxide layer on metallic components of hot CO2/H2O cycle systems, in particular of CO2/H2O gas turbine installations, in which a hydrocarbon-containing fuel is burnt with oxygen, and the excess CO2 and H2O formed is removed from the cycle system at a suitable location. To protect the oxide layer of the components which are under thermal load, an excess of oxygen is used, the level of which is dependent on the current state of the oxide layer, the state of the oxide layer being determined by periodic and/or continuous measurements.
