The effect of the atomizing pressure of fuel on thermal NO_x formation has been studied in a practical combustion system (kerosene flow rate : 14.4 kg/h) with liquid fuel pressure atomizer. The experimental results indicated that about 30% reduction in NO_x formation can be obtained when atomizing pressure is decreased from 1.37 MPa to 0.40 MPa. The decrease in atomizing pressure decreased NO_x formation by approximately 20% as compared with the standard condition in atomizing pressure at various ranges of fuel consumption rate. The results are explained in terms of decrease of the mean flame temperature caused by increasing Sauter mean diameter due to decreasing atomizing pressure. In this case, it is confirmed that both the particulates and total hydrocarbon emissions were at negligible levels in the exhaust flow ; consequently, the combustion efficiency was not affected by this simple technique for suppressing NO_x formation.
