Abstract

Interchangeabilities of biogas (BG) and liquefied petroleum gas (LPG) mixed gases according to American Gas Association (AGA) Bulletin 36 and Weaver indices were investigated. BG-LPG mixed fuels were defined so as to have a Wobbe index (WI) nearly equivalent to those of natural gas (NG). The qualities of BG and LPG used are considered by varying the CH₄ and C₃H₈ percentage in the BG and LPG composition, respectively. It was found that BG-LPG mixed gases can not be used as interchangeable gases for natural gas and can not be applied to gas appliances for natural gas directly because of yellow-tipping and incomplete combustion. However, natural gas can be substituted for BG-LPG mixed gas completely and can be applied to gas appliances for BG-LPG mixed gas without any modification. On the other hand, BG-LPG mixed gases show interchangeability with itself without any unstable flame on gas appliances regardless of the components concentration variation.
