Measurements of nitric oxide emissions are carried out on a continuous flow combustor when operating over wide ranges of fuel/air ratio at pressures up to 1.52 MPa (15 atmos). Fuel is supplied to the flame zone from a circular array of 30 equispaced miniature airblast atomizers which is incorporated into a perforated-plate flameholder. Standard instrumentation and sampling techniques are used to measure pollutant emissions over wide ranges of mean fuel drop size. The results obtained with several selected fuels demonstrate the effects of variations in fuel composition, fuel drop size, and combustor operating conditions on nitric oxide emissions.
