This study provides a clear overview of the research conducted on wood volatile combustion in a double-layer porous radiant burner (PRB). The study aims to numerically analyze wood volatile combustion within a double-layer porous radiant burner (PRB) under various operating conditions, including constant equivalence ratio (ER), power inputs ranging from 1 to 3 kw, and varying the mass flow rate of primary to secondary air inlet. The analysis employs a finite volume technique to solve a set of governing equations, including continuity, momentum, radiative transport, species transport, and energy equations for both gas and solid phases. The study reveals that the highest temperatures are concentrated in the central area of the burner and decrease radially outward. Moreover, the analysis shows that radiation efficiency decreases as input power increases but increases with secondary air mass flow rate. The maximum radiation efficiency of 36.71% is achieved at 1 kw input power and at primary to secondary air distribution ratio of 10:90, while the minimum efficiency of 21.15% is observed at 3 kw input power and at primary to secondary air distribution ratio of 50:50.
