An experimental study was conducted to assess the feasibility of achieving ultra-low NOx emissions <10 ppm) from a gas turbine through methanol firing. Baseline tests of a Saturn gas turbine generator set (800 kW) on methanol and natural gas and subscale rig tests of an advanced burner concept were conducted. Methanol fueling of the Saturn gas turbine reduced design point NOx emissions by 63 percent. The advanced combustor tests demonstrated that NOx emissions of 9 ppm (an 86% reduction) could be achieved with methanol at simulated engine design point conditions. The advanced burner was characterized by low CO and hydrocarbon emissions at full load. At part load, NOx levels remained low but CO and unburned hydrocarbons increased.
