Heat and mass transfer in a fixed bed of biomass during thermal degradation of biomass in a hot inert gas (pyrolysis) is modeled. Biomass fuel decomposes to give gas, tar and char as a result of hot gas flowing through it upwards from a combustion char below. The main heating mode at this stage is conduction and convection. The fuel bed is assumed to be a porous homogenous layer composedof uniformely distributed coarse particles that are randomly oriented. The mathematical model formulates the basic equations and solves them numerically to describe the temperature and solid fuel degradation to tar, gas and char. Thermal non-equilibrium between the gas phase and the solid particle surfaces is assumed, conseqently the use of separate equations for gas and solid phase equations is necessary
