Although investigated for many years, real-time monitoring of combustion dynamics is still an important issue in modern gas turbine operation. In this article, attention is focused on two quantities, radiant energy and pressure, sampled in an industrial combustion system. Based on such quantities, and with the aim of selecting the best operational index to detect instability precursors, different strategies are here defined and compared. Upon the obtained results, the adopted monitoring and signal analysis strategy reveals promising as an online practical method to detect combustion instabilities.

Abstract
Although investigated for many years, real-time monitoring of combustion dynamics is still an important issue in modern gas turbine operation. In this article, attention is focused on two quantities, radiant energy and pressure, sampled in an industrial combustion system. Based on such quantities, and with the aim of selecting the best operational index to detect instability precursors, different strategies are here defined and compared. Upon the obtained results, the adopted monitoring and signal analysis strategy reveals promising as an online practical method to detect combustion instabilities.File in questo prodotto:
