Development of a Test Procedure to Reflect the Real Life Operation of Pellet Stoves

Emission and energy efficiency thresholds of certification standard testing procedures for biomass room heating appliances tightened considerably during the last decades. This caused an enormous technological improvement in current stoves. As a consequence, recent pellet stoves perform excellently under type test conditions. In contrast, typical real life emissions show significantly higher values under usual operation conditions. Consequently, type testing procedures may not account for real life stove operation and, thus, do not allow to distinguish between low- and high-tech appliances. Therefore, the presented research aimed at the development of a testing method for pellet stoves that better reflects the real life operation and to support innovative pellet stoves that perform well under typical operational conditions. Based on an online survey and field observations an advanced real life testing procedure for pellet stoves was established reflecting real life user behavior and also regarding different load levels and the ignition phase. The respective method was evaluated at the test bench using different pellet stoves.
