Analysis of the Effect of Preheating System to Improve Efficiency in LPG-fuelled Small Industrial Burner☆

Abstract Nowadays, industries have been using combustion system as one of energy supply in their utility system. However, incomplete combustion process often takes place in the process, which resulted in several disadvantages for the industry such as less energy efficiency, higher CO emission and higher production cost. The aimed of this study was to understand characteristics and increasing combustion efficiency in fuel preheating system technology and to find out the effect of various initial temperature of LPG to combustion efficiency and CO emission. Results showed that increasing initial temperature of LPG from 28 °C to 50 °C would raise efficiency of the burner up to 6.75% while CO emissions decreased 49.06%. Furthermore, if the temperature increased up to 100 °C the burner efficiency would raise significantly and CO emissions considerably decreased.
