TLDR
In this paper, the influence of lean primary combustion zone operation on NOx reduction in a gas turbine combustor is examined, and the authors show that lean primary zone operation is beneficial from a NOX reduction point of view.Abstract:
Lean operation in the primary combustion zone of a gas turbine combustor is advantageous from NOx reduction point of view. The present work deals with the influence of lean primary zone operation o...read more

Active Control of Lean Blowout for Turbine Engine Combustors
T. M. Muruganandam,Suraj Nair,David Scarborough,Yedidia Neumeier,Jeff Jagoda,Tim Lieuwen,Jerry Seitzman,Ben T. Zinn +7 more
TL;DR: In this paper, an active control system was developed to permit turbine engine combustors to operate safely closer to the lean-blowout (LBO) limit, even in the presence of disturbances, using OH chemiluminescence and a threshold-based identification strategy to detect LBO precursor events.

Real-Time Prediction of Incipient Lean Blowout in Gas Turbine Combustors
Tongxun Yi,Ephraim Gutmark +1 more
TL;DR: In this paper, two indices, namely the normalized chemiluminescence root mean square and the normalized cumulative duration of lean blowout precursor events, are recommended for predicting near-lean blowout in partially premixed, liquid-fueled gas turbine combustion.
