基于马尔文激光粒度分析仪的生物质燃油雾化特性研究

Research on Atomization Characteristics of Biomass Fuel Based on Malvin Laser Particle Size Analyzer

采用马尔文激光粒度分析仪,研究了生物质燃料的雾化特性,并分析了气液质量流量比、沿喷孔轴向距离、径向距离、液体的表面张力系数以及液体的粘性系数等参数对生物质燃油雾化特性的影响。通过试验发现,气液质量流量比和沿喷孔轴向距离是影响索特平均直径的最主要因素;且在相同的雾化条件下,生物质燃油雾化质量最差,生物质燃油和醇类的混合燃料的雾化质量较好,而柴油的雾化质量最好。

By using Malvin laser particle size analyzer, the atomization characteristics of biomass fuel were studied, effects of gas to liquid mass flow ratio, surface tension of nozzle axial distance, radial distance, liquid and liquid viscosity coefficient on characteristics of biomass fuel atomi-zation were analyzed. Through the experiment, gas to liquid mass flow is the most obvious along the spray hole ratio and axial distance on the im-pact of DSMD; and in the atomization under the same conditions, the biomass fuel atomization quality was the worst, the atomization quality of blended fuel of biomass fuel and alcohol is better, and the atomization quality diesel is the best.
