A process for the plane and / or group-wise cleaning of the heating surfaces of a steam generator by means Rußbläsereinsatz

A method for Layer and group-wise cleaning of the heating surfaces of a steam generator by means Rusblasereinsatz, the method comprising the steps of: - establishing a maximum allowable effective alleviation of the heating surface, - establishing a minimum waiting time between two cleaning cycles, - setting a maximum waiting time between two cleaning cycles depending on the maximum allowable reduction in efficiency of the heating surface and - determining an optimum waiting time between the minimum delay time and the maximum waiting time in dependence on the effectiveness of the reduction of other heating surfaces of the steam generator, - wherein a cleaning operation is started after the optimum waiting time when the optimum waiting time is less than the maximum waiting time.
