Abstract

The goal of this paper is to investigate the effect factors on HiTAC of biogas, which is composed by CO, H₂, CO₂, etc. These factors mainly include O₂ concentration in oxidant, several dilutes (N₂, H₂O and CO₂), and strain rate a. The numerical analysis was carried out by means of Oppdif application of ChemKin package by using the GRI 3.0 oxidation mechanisms. Oppdif computes the diffusion flame between the two opposed nozzles with a system pressure 1atm. Firstly, influences of O₂ concentration in oxidant, such as 3%, 5%, 10%, 15%, 21%, on maximum temperature is carried out. Secondly, an analysis was made to know effects of strain rate on combustion. Finally, effects of dilute on HiTAC of biogas are provided, including N₂, H₂O, and CO₂ as dilute respectively.
