Abstract:
1. A method for operating a firing plant having at least one combustion chamber and at least one burner, the firing plant for producing hot gas, the method comprising: defining an operating characteristic for operating the combustion chamber close to a lean extinction limit, in the form of a burner group staging ratio (BGV measuring, in the combustion chamber, pressure pulsations (Puls converting said measured pressure pulsations (Puls monitoring exceeding or falling short of at least one pulsation limiting value (Puls adapting a pulsation reference value (Puls processing said corresponding signals by a filter device to produce processed pressure pulsations (Puls comparing the processed pressure pulsations (Puls determining a correction value (ΔBGV) from said comparing, wherein said determining the correction value (ΔBGV) comprises determining the dependence of the correction value (ΔBGV) on at least one amplification factor (K correcting the burner group staging ratio (BGV
