Abstract
The influence of the atomization characteristics on the combustion of heavy oil is investigated. Combustion tests are conducted in an experimental furnace with a thermal input of 0.33 MW. The characteristics of the spray produced by a simplex pressure-swirl nozzle are known in detail from a previous investigation in an atomization rig. Two cases are selected and tested under combusting conditions, while keeping constant the remaining experimental parameters. Reported results include extensive measurements of (he spatial distribution of the velocity field, temperalure and species (O2, CO, CO2, UHC and NOx inside the flame, as well as the emission of pollutants in the flue gases. The differences in the spray lead to changes in the fuel vapor distribution inside the flame. The consequences are important variations of the flame characteriscics and of the emission of gaseous and solid pollutants.
