Abstract
Temperature and gas concentration experiments have been conducted to determine the temperature at which volatiles begin to combust within the particulate phase of a bubbling fluidized bed. The particulate phase of such a bed was approximated by operating a fluidized bed at incipient fluidization. Gas concentration measurements were made from products of both premixed propane-air and premixed methane-air mixtures. The critical temperatures above which combustion products were observed in the particulate phase were 835°C and 915°C for propane and methane, respectively; below the critical temperature for each fuel-air mixture, combustion was negligible. The propane critical combustion temperature was confirmed from the results of unsteady-state temperature and ignition delay time measurements. These experiments demonstrate that the particulate phase can inhibit the oxidation rate of hydrocarbons.
