| Abstract [eng] |
Measurements of pollutant concentrations in the flue gases of a biofuel boiler show that pollutants concen-trations fluctuate by 10-100% and more at short time inter-vals. Large fluctuations in concentrations hinder the effec-tive application of pollution reduction measures. During the research, flue gas composition measurements were per-formed in 4 MW, 8 MW industrial biofuel boilers and 20 kW experimental model. The results of the research showed that the change of CO, NO, NO2, SO2, H2S, O2 and particu-late matter concentrations is related to the periodicity of the boiler grate movement. During the movement of the grate, the surface of the fuel bed is mechanically disrupted. The different composition of the fuel layers is mixed and this af-fects the changes in the concentration of combustion prod-ucts. The clarity of the concentration fluctuations depends on the emissions, the type of fuel and the combustion pa-rameters. |
