A method and system for determining a steam temperature-influencing sequence

A method for determining a steam temperature-influencing sequence for operating a plurality Rusausblaser (110, 208, 210, 212, 214, 216, 218) in a steam power generator, wherein the plurality Rusausblaser (110, 208, 210, 212, 214, 216 , 218) are used to spray a cleaning spray into a heat transfer area of ​​the steam used to generate electricity power generator, said method comprising: Operating several Rusausblaser (110, 112, 208, 210, 212, 214, 216, 218) corresponding to a Rusausblasesequenz, wherein the Rusausblasesequenz sets the flow rate of the cleaning sprays, the (of each of the Rusausblaser 110, 112, 208, 210, 212, 214, 216, 218) is used over a time sequence; Measuring the steam temperature in the heat transfer area during the time sequence; Calculating several statistical parameters of the Rusausblasesequenz; and evaluating at least one of the plurality of statistical parameters according to a first criterion, to determine whether it is in the Rusausblasesequenz to the steam temperature-influencing sequence.
