Separation of solid pollutants transported from small heat sources with chimney filters

Abstract

The review deals with the issue of environmental pollution with solid pollutants emitted into the air by small heat sources. It lists the methods and ways of separating solid pollutants released into the air by elements located directly into the heat source or outside the heat source. The attention is focused on the method of capturing solid pollutants through chimney filters. The highest efficiency (more than 90%) in capturing fine particles with a diameter of up to 2.5 μm is achieved precisely by using filters. However, the efficiency of filtration depends on various factors, such as the material composition of filters, the granularity of the material. It is also essential to regenerate the filter, i.e., to remove the applied layer or to slow down the formation of this filter layer to maintain the filter efficiency. Part of the further research is the monitoring of existing technical solutions for the construction of the chimney filter by the state of the art in available sources of patent information.
