For an ultra lean mixture of liquid fuel (Kerosene) mist and air, adiabatic combustion technology was studied experimentally using a simple perforated cylindrical hot porous ceramic burner. During the steady lean combustion, high excess air ratios; 2.8～3.6 could be achieved through the range of fuel now rate; 0.8～4 g/min. The emission levels of CO and NOx under the excess air ratios less than 2.0 were satisfactorily low. The effects of fuel flow rate on the emission levels were examined, and the mechanisms of flame confinement in the perforated cylindrical hot porous ceramic were discussed in detail. It was shown that the adiabatic combustion method of liquid fuel mist in a hot porous ceramics can be promising combustion technology for many applications owing to the ultra lean mixture condition, the strong light emission and the strong thermal radiation.
