The fundamental characteristics of particulate matter and NOx formations by the oxygenated components fuel oil are studied experimentally. This work uses a high quality biomass (Edible Oil) for the oxygen containing fuel oil. Profile of particulate matter and NOx concentrations together with gas species concentration, temperature and spray behaviors are measured in the spray flames of two different fuels: pure Kerosene added Edible oil in the ratio of 70/30 v/v. % . The nozzle type for atomization is used an ultrasonic generator without precedent.
When the biomass (Edible oil) fuel oil is used, the gas temperature on the flame axis increases by 100-150°C, is raised as OH radical and O₂ concentration increases. Both of the particulate matter formation and decomposition rates increases, the final exhaust of PM is reduced. NOx concentrations in the both flames is no significant difference in the downstream region.
