Using biomass for thermal and electric power generation is now one of the possibilities of reducing CO2 emissions. In many cases, this requires an application of a biomass gasification installation. Because biomass properties can vary to a great extent, the existing gas generators need continuous upgrading. The research in this area should comprise both on-site testing carried out at real facilities and numerical modelling. The results of the works will make it possible to construct a gasifier featuring an appropriate structure and contribute to a better understanding of the gasification processes occurring in the biomass bed. This paper presents an attempt to develop an appropriate mathematical model for an existing low-capacity fixed-bed gasifier. Alder chips made up the biomass to be analyzed and air was the gasifying medium. An innovative biomass gasifier called GazEla, with the nominal thermal power output of 60 kWt, was selected for the purposes of numerical modelling. The main object of the analysis was to build a three-dimensional model of the gasifier and to obtain the outlet gas composition similar to experimental data. The porous body model served as the model of the biomass fixed bed and char. Selected chemical reactions reflected typical combustion and gasification processes occurring in fixedbed gasifiers.
