Study on combustion characteristics of different compositions of LPG
Varieties of liquefied petroleum gas (LPG) are based on variety composition of propane and butane. The common composition of LPG contains 70% or 60% volume of butane and 30% or 40% volume of propane. However there have some variations of LPG composition as dictated by its usages and applications. Be...

| Summary: | Varieties of liquefied petroleum gas (LPG) are based on variety composition of propane and butane. The common composition of LPG contains 70% or 60% volume of butane and 30% or 40% volume of propane. However there have some variations of LPG composition as dictated by its usages and applications. Because of the different composition between propane and butane in LPG that used today, it can give different combustion characteristics of the LPG. The objective of this work is to study and analyze the combustion characteristic for different composition of LPG. The scope of this work is to analyze the energy that released which is commonly known as calorific value (CV), to determine the flame speed and to analyze the emission for different composition of LPG. The results get from this research are the calorific value of LPG that contains more butane is higher than one contains more propane. Beside that, the emission from LPG combustion is increased with the number of hydrocarbon in the LPG composition. Finally, the flame speed is decreasing when the composition of hydrocarbon is higher; in other word it decreases when LPG is contains more butane. The LPG that contains higher number of hydrocarbon can give more quantity heat by its combustion but the flame speed from it combustion slower and it also gives a higher effect to environment. The variation of composition in LPG gives an effect to their combustion characteristics. The research of combustion characteristic can optimize if using the sample of LPG that contain the other composition. Beside that, the other combustion characteristic like flammability limit also can be added to see the view of safety aspect when using the different composition of the LPG. |
