At these conditions CO and UHC are almost inexistent, i.e, near to zero. The exception to these levels is observed for 50° and 60°. NOx emissions suffer the largest increase between Φ = 0.4 and 0.6, after this interval the pollutant concentrations have a behavior without fluctuations and with values below 40 ppm. In gas turbine operation global equivalence ratios can reach 0.15, making it necessary to inject an additional air supply at a dilution region, positioned after the secondary chamber.
