2019-9-18 · This control method can reduce NOx emissions levels from syngas-fired turbines to approximately 15 ppm (at 15% O 2). General Electric (GE) is currently targeting development of combustors to reliably achieve below 10 ppm NOx with syngas, which would be comparable to the NOx emission levels achieved through use of the lean-premix technology on gas turbines firing natural gas.
