| Abstract | This article presents a numerical study of combustion of low-calorific-producer-gas from Mangium wood within alate mixing porous burner (LMPB). The LMPB consists of four main components, i.e., the fuel preheating porous (FP), theporous combustor (PC), the air jacket, and the mixing chamber. Interestingly, this LMPB was able to highly preheated andit still maintained high safety in operation. A single-step global reaction, steady state approach and a one-dimensional modelwere considered. The necessary information for burner characteristics, i.e., temperature profile, flame location and maximumtemperature were also presented. The results indicated that stable combustion of a low-calorific-producer-gas within LMPBwas possible achieved. Increasing equivalence ratio resulted in increasing in the flame temperature. Meanwhile, increasingthe firing rate caused slightly decrease in flame temperature. The flame moved to downstream zone of the PC when the firingrate increased. Finally, it was found that the equivalence ratio did not affect the flame location. |
