BEHAVIOR OF FLAME PROPAGATION IN LPG PREMIXED COMBUSTION WITH CARBON DIOXIDE INHIBITOR

Abstract

This study was focused on the inHuence of carbon dioxide on the behavior of LPG premixed flame propagation in cylindrical combustion chamber. The combustion chamber was made of transparency acrylic cylinder so that behavior of flame propagation from the ignition source could be recorded With high speed camera at various mixture concentrations. Ion sensor made of aluminum foil having oirnensrorr 20 em long, 2 em wide were Installed on the two Sides of the chambers wall for detecting the behavior of Ion dunng flame propagation. The results showed that the carbon dl~de decreases velocity of LPG name propagation. The Ion concentrabon In the flame With carbon diOXide was also shown the different behavior. These indicated that carbon dioxide reduced reaction rate of LPG premixed cornbuston,
