초록
This study was performed to provide the basic information of the combustion, CO and NOX characteristics of biodiesel in accordance with equivalence ratio. The closed homogeneous reactor model used for the analysis. The analysis conditions were set to 900 K of the initial temperature, 20 atm of initial pressure and equivalence ratio was changes from 0.6 to 1.4. The results of analysis were predicted and compared in terms of combustion temperature, combustion pressure, CO and NOX emissions. The results of combustion characteristics showed that ignition delay was decreased and the combustion temperature and combustion pressure was increased in accordance with equivalence ratio. CO emission was decreased in lean condition(Φ < 1.0), however, CO emission was increased in rich condition(Φ > 1.0) because oxygen supply insufficient. NOX emission showed the largest amount in condition 0.8 of equivalence ratio because the oxygen concentration was sufficient.
Abstract
This study was performed to provide the basic information of the combustion, CO and NOX characteristics of biodiesel in accordance with equivalence ratio. The closed homogeneous reactor model used for the analysis. The analysis conditions were set to 900 K of the initial temperature, 20 atm of initial pressure and equivalence ratio was changes from 0.6 to 1.4. The results of analysis were predicted and compared in terms of combustion temperature, combustion pressure, CO and NOX emissions. The results of combustion characteristics showed that ignition delay was decreased and the combustion temperature and combustion pressure was increased in accordance with equivalence ratio. CO emission was decreased in lean condition(Φ < 1.0), however, CO emission was increased in rich condition(Φ > 1.0) because oxygen supply insufficient. NOX emission showed the largest amount in condition 0.8 of equivalence ratio because the oxygen concentration was sufficient.
