N2  - In recent years, syngas has gained research interest as the focus shifts from fossil to renewable fuels. Syngas generated from biomass such as wood, agricultural residue, and paper is a promising fuel to achieve net-zero carbon emissions. It is mainly composed of CO, H2 and diluents such as CO2 and N2. The combustion characteristics of biomass-derived syngas significantly differ from the well-studied fuels in terms of calorific value, stoichiometric fuel-to-air ratio, ignition delay, and flammability limits. In the present study, a combination of catalytic and swirl combustion is explored using a two-stage combustor to achieve low emissions without losing combustion stability. The first stage is the catalytic stage, and the second stage is the swirl stage. A preheated and premixed syngas-air mixture (Фfirst = 4) is supplied to the first stage, where syngas is consumed partially. The remaining unburnt fuel is combusted using an oxidizer in the second stage
