ABSTRACT:
Method and apparatus for diagnosing ignition failure conditions in a combustion turbine are shown to generally include referencing members for generating a plurality of reference signals, wherein each of the reference signals are representative of a desired ignition operating condition, sensors for sensing actual ignition operating conditions each of which correspond to a desired ignition operating condition. The sensors generate a plurality of operating signals representative of actual ignition operating conditions. Comparators are utilized for comparing each of the operating signals to a corresponding reference signal and to indicate when the operating signal exceeds the reference signal in the presence of an ignition enabling signal.
