Dr Eng. Krzysztof Czajka, scientist of the Faculty of Mechanical and Power Engineering of the Wrocław University of Science and Technology, together with specialists of KGHM Cuprum R&D Center, developed a cheap, easy-to-install chimney filter. The invention absorbs not only dust, but also gaseous pollutants.
Dr Eng. Krzysztof Czajka of the Department of Mechanics, Machines, Devices and Energy Processes started cooperation with the Research and Development Center of KGHM Cuprum. Together with the employees of the local Department of Energy Technologies, he worked on an anti-smog chimney filter that will help reduce exhaust emissions from old boilers and domestic fireplaces.
The scientist and KGHM specialists developed a prototype of a filter with a carbon bed at its heart. According to the first measurements it reduces dust emissions by approx. 70 percent. and captures about 60 percent of the sulfur oxides and 15 percent nitrogen oxides from the exhaust gases. The prototype will be tested in the heating system this winter.
