Abstract:
Batch fired wood stoves are popular and widespread in Europe. However, since they contribute significantly to harmful emissions, they have to be optimized towards clear emission reduction, especially in real life. Besides technological aspects, the user behavior (i.e. ignition mode) and draught conditions also affect combustion quality significantly. Therefore, this study aimed at an investigation of optimization effects of user behavior and catalyst integration regarding emissions and thermal efficiency. Comparative combustion test series using a modern (expensive) as well as conventional (cheap) firewood roomheater were performed under controlled and natural draught conditions. The typical and best-practice user behavior was compared. Additionally, the effect of an integrated metallic and ceramic catalyst on combustion quality was assessed applying the typical heating operation. The results showed for both tested roomheaters that catalyst integrated solutions are most effective for emission reduction (up to 90% for CO) as well as thermal efficiency increase due to its primary effect on the air supply of the appliance. Further, no operational problems occurred under natural draught conditions.
