Georgia Tech Researchers Create a Low-Emission, Fuel-Flexible Combustion System

Lieuwen and his research group are developing a new type of all-purpose combustor that can use any type of fuel while still maintaining low emission standards. Their non-premixed, rich, relaxation, lean (NRRL) combustor works just as well as current mixed-fuel type combustors — but without instability.
