Abstract:
Smallscale wood stoves are a climate friendly and costeffective solution for buildings with low energy demand. However, those appliances contribute significant shares of gaseous and particulate emissions all over Europe. The integration of an oxidation catalyst system into a stove can reduce emissions significantly. Aim of this study was to specify a method for precise evaluation of catalyst performance in logwood stoves under “real life” conditions in a costand timesaving manner. A test stand was developed allowing for the control of gas quality, flow rate and gas temperature according to the expected operation conditions of a catalyst. Conversion rates are evaluated directly by comparing emission concentrations of carbon monoxide, volatile organic carbon, methane and total suspended particles ahead and past the catalyst. Various tests were conducted to illustrate the performance of the test stand for catalyst evaluation. For each respective gas component, individual conversion rates were determined. Due to parallel measurements upstream and downstream of the catalyst, the usually high fluctuation in gas composition is not disturbing the accuracy of the measured conversion rates.
