Abstract

Computational fluid dynamics (CFD) was used to simulate the combustion practice of the gases
that produce from gasification process. In this simulation a new air-assisted flare design which
capable to handle low flowrates of these gases with high performance was used. The simulated
cases were performed by using the gases that produced in the downdraft gasifier at our lab. Wood
pellet was used as the biomass feedstock of the gasification process in the current study which
results mainly CO, H2, CH4, and CO2 as gasification gases. Different low flowrates of these gases
were used in the simulation. The non-premixed Steady Diffusion flamelet combustion model was
used in this study with 22-species reduced reaction mechanism to predict the combustion
efficiency of gasification gases. The results show a good flare performance when the new flare
design is used.
