On Accurate and Reliable Anomaly Detection for Gas Turbine Combustors: A Deep Learning Approach [PDF]
PHM 2015 Conference, 2019 Monitoring gas turbine combustors health, in particular, early detecting abnormal behaviors and incipient faults, is critical in ensuring gas turbines operating efficiently and in preventing costly unplanned maintenance. One popular means of detecting combustor abnormalities is through continuously monitoring exhaust gas temperature profiles.

Gas turbines for polygeneration? A thermodynamic investigation of a fuel rich gas turbine cycle
International Journal of Thermodynamics, 2011 Gas turbines as used nowadays are working far in the fuel lean regime, which is most reasonable for mobile applications, since the formation of pollutants and soot are avoided while the temperatures remain low enough to avoid damage of the turbine. However, from a thermodynamic point of view the exergy utilization is far from optimum at such conditions.

Assessment of existing H2/O2 chemical reaction mechanisms at reheat gas turbine conditions [PDF]
arXiv, 2011 This paper provides detailed comparisons of chemical reaction mechanisms of H2 applicable at high preheat temperatures and pressures relevant to gas turbine and particularly Alstom's reheat gas turbine conditions. It is shown that the available reaction mechanisms exhibit large differences in several important elementary reaction coefficients.

Numerical Simulation and Aerodynamic Optimization of Two-Stage Axial High-Pressure Turbine Blades [PDF]
arXivGas turbine engines are highly efficient and powerful because of their high-pressure turbines (HPTs). Furthermore, stationary blades shape and prepare high-pressure gas for efficient utilization by moving blades. Consequently, optimizing the geometric features of both stationary and moving blades during the first and second stages of HPT is necessary ...
