Biomass, as well as any other fuel, emit certain pollutants during combustion, which should not be neglected. The emission of nitrogen oxides (NOx) generated during biomass combustion, especially agrarian оne, is one of the key challenges for the use of this fuel. In order to investigate the potential of emitted NOx reduction, the experimental denitrification chamber was designed. The secondary denitrification technique of selective non-catalytic reduction (SNCR) on a synthetic mixture of gasses simulating real flue gasses during biomass combustion was tested. This paper provides a description of the experimental denitrification chamber as well as the experimental results obtained as the function of flue gas temperature, NO concentration, and NH3/NO molar ratios. The optimization of the denitrification process under controlled conditions provided by the experimental denitrification chamber is the starting point for the optimization of the SNCR process on real-scale plants combusting biomass or any other fuels with increased NOx emission.
