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