Abstract
The objective of this work is the calculation of the laminar flame speed of the gas from lignocellulosic biomass gasification, using two different reaction mechanisms. Varying both the gas composition and the excess air within the engine, the flame speed was calculated by using the CHEMKIN code, and obtaining correlations depending on pressure and temperature. As a result of this study it was found, through comparison with experimental results, that the GRI-Mech mechanism is more suitable than that proposed by Miller-Bowman, and that the CO:H2 ratio is the gas parameter having the greatest influence on the flame speed. It was also observed that both mechanisms predicted a maximum in the laminar flame speed for rich gas-air mixtures.It is concluded that the method employed for calculating the speed of combustion is appropriate for the pressure and temperature intervals considered.
