Original Abstract
With the growing proportion of thermally removal waste relate tightening of emission limits for exhaustion of pollutants into the atmosphere. It is therefore necessary to come up with new, more effective but also economically acceptable methods. Current secondary methods for disposal of hazardous pollutants contained in flue gas mostly require the installation of separate equipment for each of the controlled pollutants. To remove solid pollutants (ashes) are used fabric filters, ESP (electrostatic precipitator) or cyclones. The destruction of NOX is used SNCR (selective non-catalytic reduction) or SCR (Selective Catalytic Reduction). Acid components of flue gas (SO2, HCl, HF) is often removed dry, semi-dry or wet scrubber, VOC and PCDD/ F are removal such as using activated carbon adsorbers, etc. The article deals with the selective catalytic reduction of nitrogen oxides at fabric and ceramic filters with v implemented catalyst. Passing flue gas through the wall of filter is also to remove solid pollutants. This combination can be termed as a catalytic filtration. Used catalysts also allow decomposition of PCDD/ F at an acceptable pressure drop. Objective research is primarily overall evaluation filtration materials, evaluation of economic aspects and comparison with current methods of NOX reduction. To verify and quantify these assumptions have been built the experimental unit capable to simulate of operating conditions occurring in real plants.
