Abstract:

Aiming at the mechanism of alcohol-based fuel burner with the diffusion combustion of methanol fuel,the Arrhenius limited reaction rate model and the eddy break-up combustion model are established,and numerical simulation and field synergy analysis are conducted by taking into consideration the heat loss due to convection and radiation. The results show that,when the excess air coefficient is 1. 1~1. 2,the mass fractions of NOx and CO at
the burner outlet are both low,while both the average temperature and the maximum temperature are high,thus bringing about excellent performance on the part of the burner; furthermore,when the pressure is 0. 18~0. 19 MPa,the synergy between the velocity field and the temperature field proves to be the best,thus the best effect of the alcohol-based fuel burner being achieved.

Key words: alcohol-based fuel, combustion, field synergy principle, pollutant, numerical simulation
