Abstract

Batch-wise operated wood stoves for room heating purposes are popular and widespread in Europe. Beside economic and ecological reasons they are also very important for reaching the European CO2 emission targets. However, since they contribute significantly to harmful gaseous as well as particulate emissions, they have to be optimized towards clear emission reduction in real life operation. Catalysts integrated in wood stoves can significantly contribute to reach this target. The results of this study showed an emission reduction potential of
integrated ceramic and metallic honeycomb catalysts of around 30 % to 99 %. Thereby the highest reduction potential was investigated for CO emissions (reduction rate 75 % to 99 %), followed by reductions of VOC emissions (reduction rate 40 % to 60 %) and reductions of PM emissions of around 30 % to 40 %. Long term tests and safety test series lead to the conclusion that integrated catalysts have to be cleaned regularly in order to prevent blocking and to guarantee optimal reduction performance.
