Abstract

This research is to study the combustion characteristics of liquefied petroleum gas (LPG) on a Wolfhard Parker slot burner, which is a prototype burner using in the industrial sector. The Wolfhard Parker slot burner applied with non-mixed combustion can provide the uniform heat flux, and it is safe to use with less chance of flash back flame. However, non-premixed combustion usually affects the incomplete combustion, combustion efficiency and combustion characteristics such a diffusion flame due to the fuel compositions and equivalence ratios. This research focuses on the combustion of liquefied petroleum gas on a Wolfhard Parker slot burner due to the influence of LPG composition (propane and butane ratio) in applications according to the ratios of 70:30, 60:40, 40:60, heat input rates of 2.00-4.00 kW and equivalence ratios of 1.00-2.00. As the results, it was found at Eauivalence ratio 1.00 or a heat input rate of 2.0 kW with a LPG composition ratio of 70:30, the highest premixed flame ratio and the maximum flame temperature (940°C). For LPG composition ratio of 60:40 the flammability limit was wider. In addition, the lowest carbon monoxide was emitted at LPG composition ratio of 40:60. As the results of LPG combustion on a Wolfhard Parker slot burner, the composition of LPG, equivalence ratio and heat input rate could effect on the flame temperature, premixed flame length ratio, flammability limit and carbon monoxide content however it has slight influence on oxide of nitrogen content.
