Rediscovering Fire: Advancements in Gas Turbine Combustion
Gas power market drivers and a quest for relevance in future decarbonized systems are driving fundamental shifts in gas turbine combustion design approaches.
Combustion lies at the heart of gas turbine technology. It provides the core function of adding heat, through a controlled burn of large amounts of fuel and air, to a gas turbine’s conversion of chemical energy into mechanical energy and, for power generating turbines, electrical energy. In concept, a combustor essentially comprises a fuel injector and a wall to contain the flame. But far from simplistic, the process must achieve a delicate balance of equivalence ratio between the fuel and available oxygen; flame stability; and operational stability to support accele
