Due to the continuous growth of energy consumption it is required that development in the energy sector is focused on renewable energy sources. Another possibility to reduce the consumption of primary energy resources is also searching for new and non-traditional fuels. Stalk and slightly contaminated biomass are representatives of these non-traditional fuels. Stalk is mostly annual plants grown primarily for subsistence. Waste parts of these plants can be utilized for production of energy. The thermal gasification is one of the possibilities to use biomass efficiently. Gasification can be understood as the thermo-chemical conversion of solid fuel into the gaseous state. The gas with low heating value is on the outlet from gasification process. The main components of produced gas are hydrogen, carbon monoxide, and methane. The final gas contains also a lot of undesirable constituents which handicap this gas for energy usage. These constituents are neutral components, that dilute gas only, and pollutants as dust, tar and compounds of sulphur and chlorine, which complicate further use of the generated gas.  The research paper is focused on thermal gasification of stalk and other non-traditional fuels in Biofluid experimental device. The aim is to design methods for cleaning the raw gas from the tar compounds. The research is focused on the secondary gas cleaning methods aiming at high purity of the final gas.
