Abstract

Energetic use of biomass by combustion of wood in log-fueled fireplaces becomes more and more attractive. In-situ sensor-based flue gas analysis could help to efficiently reduce emissions. Firing experiments were carried out with simultaneously collected data about flue gas composition. This includes FTIR gas analysis, particle emissions concerning amount and size distribution (particle spectrometer), several temperature sensors and a lambda probe to determine the residual oxygen concentration beside the data from an inhouse developed sensor, that is sensitive to combustible gases. The sensor results impressively follow the FTIR data. Further investigations and data analysis should focus on correlations between sensor (incl. secondary data) and particle analysis to clarify whether gas sensor data might hint on particle emissions.
