摘要:
采用司班-80(Span-80)/吐温-80(Tween-80)复合乳化剂,制备了由生物质油/柴油混合而成的乳化油,研究了HLB值、生物质油掺和量对乳化油稳定性的影响.在乳化油燃烧试验装置上,研究了乳化油燃烧及SO2,NOx和CO等气态污染物排放特性.结果表明:生物质油体积分数不超过15%、乳化剂HLB值在7.0~8.0之间时,乳化油具有较好的稳定性.随着烟气中含氧量增加,乳化油燃烧温度增加,烟气中SO2和CO浓度减少,NOx浓度增加.与柴油燃烧相比,乳化油燃烧产生的SO2,CO,NOx浓度较低,火焰明亮度较高,且火焰外沿有交叉闪光现象.乳化油可作为替代石油的燃油,但需解决乳化油偏酸性、排烟热损失大、黏度高等不利因素带来的问题.
Abstract:
By using emulsifiers of Span-80 and Tween-80, the emulsion was prepared by bio-oil and diesel oil. The effect of HLB(hydrophile lopophik balance)value and volume fraction of bio-oil on the stability of emulsion was studied. The combustion and gaseous pollutants characteristics of emulsion were also studied. The results can be summarized as follows: when the volume fraction of bio-oil is not more than 15% and the HLB value is between 7.0 and 8.0, emulsion can remain stable. With the increase of oxygen in flue gas, the combustion temperature and the NOx concentration of emulsion are increased, and the concentrations of SO2 and CO are decreased. The combustion temperature and the concentrations of SO2, NOx and CO of emulsion are lower than those of diesel oil with the same flue gas oxygen. Compared with diesel oil flame, the flame of emulsion has higher brightness and the outer edge of flame shows cross-flash phenomenon. Emulsion can be used as an alternative oil fuel, but the problems of lower acidity, larger exhaust heat loss, higher viscosity need to be solved.
