METHOD FOR OPERATING A FIRING PLANT
A method for operating a firing plant with at least one combustion chamber and at least one burner, especially a gas turbine, includes an operating characteristic for operating the combustion chamber close to the lean extinction limit defined as a burner group staging ratio (BGV Rich) . Pressure pul...

| description | A method for operating a firing plant with at least one combustion chamber and at least one burner, especially a gas turbine, includes an operating characteristic for operating the combustion chamber close to the lean extinction limit defined as a burner group staging ratio (BGV Rich) . Pressure pulsations (Puls Actual) measured in the combustion chamber are processed by a filter device (2) and converted into corresponding signals (Puls Actual,Filter(t)) .cndot. An exceeding/falling short of at least one pulsation limiting value (Puls Limit) is monitered by a monitoring device (3) and adapts a pulsation reference value (Puls Ref) in dependence upon the monitoring. The processed pressure pulsations (Puls Actual,Filter(t)) are then compared with the adapted pulsation reference value (Puls Ref,adapt) , and, from this, a correction value .increment.BGV is determined, by which the burner group staging ratio (BGV Rich) is corrected, and as a result operation of the firing plant close to the lean extinction limit may be realized. |
