Development and application of a biomass burner using nyamplung seed cake as feedstock for pyrolysis process

The main issue in running the pyrolysis plant for waste plastics and waste tire is how to operate the plant efficiently with the minimum energy required for heating the reactor. Therefore, the alternative heating source for the pyrolysis reactor should be applied to reduce the energy cost. Development of a novel biomass burner has been successfully fabricated, tested and applied for pyrolysis system. The experiments have been conducted to study the effect of air supply and fuel on the combustion performance of the burner. The results show that the thermal efficiency of the burner was higher by utilizing nyamplung seed cake as a feedstock compared to wood pellet. However, the maximum flame temperature of nyamplung seed cake was lower than that of wood pellet. This is due to the lower density of nyamplung seed cake compared to wood pellet which was lowering the combustion rate in the burner. The increase of the air supply generates the increase of the maximum flame temperature and the decrease of thermal efficiency. Moreover, the higher air supply the higher the flame length would be in which it will be one of the important parameters when designing larger scale of biomass burner and the pyrolysis reactor.
