Abstract A novel heat pipe biomass gasifier was developed to improve the heating value of gas produced. Based on the mass balance, energy balance and dynamics of chemical reactions, a kinetic model was developed to simulate the process of biomass gasification and experiments were performed. By testing and simulation it shows that the kinetic model is consistent with testing results. By comparing the results of the gas composition and heating value with those produced by direct heat supply using air, it is found that hydrogen content in gas composition produced in the heat pipe biomass gasifier is approximately ten times of that in direct heat supply gasification using air.
