Abstract
The effect of fuel properties on the temperature distribution and emissions in a swirl type combustor was studied. The fuels used were gasoline, kerosene and heavy oil. Gasoline and heavy oil were used as the most and the least volatile fuels respectively. The momentum flux and the Sauter mean diameter of the issuing sprays of three fuels were controlled to have the same value. The difference of the temperature distributions between the flames was prominent in a non-swirling flow condition. Emissions of soot and NOx took high values in the heavy oil flame and low values in the kerosene flame. Under the heavy oil combustion, exhaust emission of NOx increased by decreasing the swirl strength of the flow. Exhaust soot emission increased by increasing the swirl strength of the flow for all three fuels.
