Abstract:

 

In wildland fire the gaseous fuel released from the  pyrolysis of vegetation fuels is a complex and highly variable mixture  which include CO, CO2, CH4, H2 and light hydrocarbons.  A detailed  study of the gas-phase oxidation of such a mixture is reported.  The  experiments were performed in a perfectly stirred reactor (PSR) at 1  atm, over the temperature range 773 -- 1273 K and for equivalence  ratio of 1 and 1.2.  Mole fractions versus temperature were obtained  for molecular species (reactants, intermediates and products).  These  measurements were used to record the behavior of several species  during the combustion of a typical pyrolysis gas mixture released from  a Mediterranean species involved in wildland fires.  Experimental  results were compared to the simulations obtained with the CHEMKIN PSR  code.  Two detailed mechanisms developed for the oxidation of methane  were tested The simulated and experimental results are in good  agreement for the mixture investigated.
