Utilization of gasified biomass in the case of combustion could introduce a prominent way to high energy efficiency, pollutant emissions reduction, and heat recovery purposes. In this paper, secondary syngas combustion chamber of high temperature agent gasification (HiTAG) system is modelled with computational fluid dynamics (CFD) techniques. The numerical data in terms of temperature distribution and flue gas concentrations are compared with experimental measurements through the whole volume of such chamber. In order to reduce the pollutant emissions, and more efficient volumetric combustion, a low NOX burner is used in the secondary chamber. The validation of numerical results with experimental measurements shows a good consistency through the entire chamber. It is concluded that the NOX emission due to secondary air injection, and low NOX burner decreased significantly prior to spread in atmosphere. Moreover, the concentration of oxygen and carbon monoxide at the combustion exhaust reveals a reliable combustion system.
