Abstract
A method for influencing and monitoring the oxide layer on metallic components of hot CO/HO cycle systems, in particular of CO/HO gas turbine installations, in which a hydrocarbon-containing fuel is burnt with oxygen, and the excess COand HO 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.
