【Abstract】 In this paper, numerical simulation for the pyrolysis process of a single globular biomass particle is made. The DRBEM is used to solve the nonlinear heat transfer equation, and the forth-order Runge-Kutta method is used for solving the chemical kinetics equations. The effect of the biomass particle size and the ambient temperature on pyrolysis tune and mass fraction of some products are discussed.更多还原
