摘要
通过对沼气燃烧器进行燃烧参数优化的试验研究,明确各参数对燃烧性能的影响规律,为进一步设计和改进沼气燃烧器提供基础技术参数。试验通过采用多因素多水平设计,对数据进行处理后得到热负荷、热效率与试验因素之间的回归方程,并通过等值曲线曲面分析了试验因素对性能指标的影响规律以及之间的交互作用,最后经过对试验结果的回归分析和参数优化,得到了沼气燃烧器的最佳工作组合为:沼气流量3.0m3/h、喷口直径6.0mm、一次空气量系数0.61;并且进行了验证,得出的实际值与预测值非常接近,表明了优化结果的合理性。
Through the experimental study on optimizing combustible parameters of biogas burner,t wanted to make clear its performance parameters on the effect to the biogas burner,providing basic technical parameters for the design and improvement in the further.By using multi-parameter and multi-level in the experimentation and depending on professional software（DX7）,it gained the heating load and thermal efficiency regression equations among testing factors.Through isovalue contour surfaces it analyzed the influent performance and the interaction.Based on the experimental results,it received the optimizing combustible parameters： biogas flow was 3.0m3/h,spout diameter was 6.0 mm and primary air coefficient was 0.61.Then,the verification of the actual and forecast is very close that the optimization of results was rational.
