Flammability limits of propane in air at elevated temperatures
The flammability limits of propane in air were determined at elevated initial mixture temperatures (up to 350 degree C) at atmospheric pressure for upward flame propagation in a stainless steel test tube apparatus. The fuel-air mixtures were exposed to elevated temperatures over different periods of time ranging from 2 minutes to 2 hours before spark ignition to investigate the existence of pre-ignition reactions at these levels of temperature that may influence the value of the limits. Temperature and pressure of the mixture were recorded continuously during the tests. Gas analysis was also carried out. It was shown that the rich flammability limit of propane in air established in the absence of cool flames increased approximately linearly with the temperature up to 300 degree C. At higher temperatures the limit narrowed and was significantly affected by the exposure time. Moreover, cool flames were observed in very rich mixtures (up to 90% of propane) at temperatures higher than 300 degree C.
