摘要

使用传统本生灯的沙特液化石油气/空气混合物的等效比范围在22.77至42.93之间。沙特液化石油气/空气混合物的传统本生灯存在操作问题,特别是在稀薄混合物中。因此,本生燃烧器被成功地改造,以克服使用不同的沙特液化石油气/空气混合物的限制,并获得稳定的火焰。使用改进的本生灯,等效比范围在0.68 ~ 1.30之间。改良的本生灯采用预混火焰。将MATLAB算法成功应用于火焰图像处理和层流燃烧速度的测量。在化学计量条件下,使用沙特液化石油气/空气混合物的改良本生燃烧器确定层流燃烧速度约为35±0.91 cm/s。火焰半锥角为16.20±0.76°。最小火焰高度在本生灯出口上方21.50±0.22 mm处。

The Characterization of Liquefied Petroleum Gas (LPG) Using a Modified Bunsen Burner
The equivalence ratio ranges were found between 22.77 and 42.93 for the Saudi LPG/air mixture using a traditional Bunsen burner. An operation problem was found with a traditional Bunsen burner for the Saudi LPG/air mixture, especially in a lean mixture. Therefore, a Bunsen burner was successfully modified to overcome the limits of operation with different mixtures of Saudi LPG/air and a stable flame was obtained. The equivalence ratio ranges were found between 0.68 and 1.30 using the modified Bunsen burner. A premixed flame was used for the modified Bunsen burner. A MATLAB algorithm was successfully applied to flame image processing and measurement of laminar burning velocity. The laminar burning velocity was determined to be approximately 35 ± 0.91 cm/s under stoichiometric conditions using the modified Bunsen burner for the Saudi LPG/air mixture. The half-cone angle of the flame was found to be 16.20 ± 0.76°. The minimum flame height was observed to be 21.50 ± 0.22 mm above the Bunsen burner exit.
