Impact of chimney on low emission

The air pollution caused by operation of heating devices using solid fuels is a significant problem in Poland and neighbour countries. The pollution level is so high, that some voivodships impose anti-smog acts, banning the use of heating devices which do not meet requirements of the 5th class according to EN 303-5. By 2023 the ban is going to be imposed nationwide. In order to improve the air quality, heating devices' producers take constant measures to improve their products. It is recently expected that those devices meet the strict 5 th class emission requirements, as well as other directives' requirements, including the Ecodesign Directive 2009/125/EC. However, the emission results achieved during initial test of heating devices in laboratory may be much worse during operation in real operating conditions. The research included tests proving that the chimney system applied to a heating device might influence the emission of particles exhausted with the smoke. The tests have been performed in real-life conditions, on a test rig that was prepared for this purpose. The research has proved that emission values of heating devices will change, chimney system applied.
