Combustibility of petroleum was investigated with high temperature air combustion technology. Ultra low NOx emission (∿10ppm) was achieved both for the kerosene and heavy oil A as fuels using a 0.4MW class test furnace. Thermal NOx was extremely reduced as decreasing the air ratio and fuel NOx was also reduced when the combustion was conducted at low oxygen concentration. Introducing the high temperature (∿1000℃) steam could decrease the NOx emission. As decreasing the air ratio, the flame was enlarged and flameless oxidation was observed. Under the low NOx combustion condition uniform distribution of temperature and chemical species were confirmed.
