Abstract:The gasification experiments of corn stalk and sawdust were carried out, and the effects of gasification parameters on the evolution of fuel bound nitrogen were analyzed. The results showed that, comparing with the equivalence ratio, the gasification temperature has a more obvious influence on the nitrogenous species concentrations. NH3 and N2 are major nitrogenous species and their variations along with the gasification temperature are opposite. The conversion reaction between NH3 and N2 is an important thermal-chemical process which determines the evolution of fuel bound nitrogen during the biomass gasification.
