The results of an experimental test program to determine the combustion characteristics of high combustion intensity and low pollutant emissions are presented. Fine fuel spray with wide spray angle formed from a twin-fluid atomizer was effectively mixed with high-swirl air near the atomizer in the cylindrical combustion chamber, and could be fired under the conditions of combustion intensity up to 20 MW/m^3 to yield stable ignition and good combustion efficiency. NO_x emissions in exhaust gas were affected by combustion states, burnt gas temperatures and O_2 concentrations. They attained to maximum values at the air excess ratio of 1.1 〜1.2 for each combustion condition and were prominantly reduced with increasing or decreasing or decreasing in air excess ratio.
