Numerical study for the combustion analysis of wood volatiles in porous radiant burner for the application of biomass cooking stove

Experimental investigation of the use of a radiant porous burner in a novel dual hot air generator based on the food drying process

“…Notably, the HAG-D design is based on the food drying process, but the results of this work can be extrapolated to diversify the potential applications for these unit systems. The radiant porous burner (Figure 2) can operate at up to 20 kW and has a burning rate of 2500 kW/m 2 , which is remarkably higher than for other burners found in the literature (Dash et al, 2023;Yakovlev et al, 2021;Zainith & Mishra, 2024). It has a preheating zone composed of a low-porosity and less conductive material (Al 2 O 3 -SiO 2 , flame arrestor) and a combustion zone above the preheating zone, which consists of a highly porous, radiant, and conductive material (Si-SiC).…”

“…The burning rate of these materials varied in the range of 200-400 kW/m 2 at low power of 1 and 3 kW. Moreover, Zainith and Mishra (2024) explored the combustion behavior of volatile organic compounds in a radiative burner using SiC as a porous solid. Temperatures, gaseous emissions, and radiation efficiencies were analyzed for different powers (1-3 kW) and porosity ranges (0.7-0.9).…”
