Abstract

Single-room wood-log fueled fireplaces are widely used but contribute significantly to harmful emissions such as carbon monoxide and fine dust. Automatically controlled operation might help to reduce health risks and environmental pollution. Therefore, in-situ measurements in the flue gas are necessary to intervene by controlling the combustion air stream automatically. As the detection of particulate matter in mass, concentration or size distribution is challenging – there are no suitable sensors available -, the particle emission shall be estimated by gas sensor data. We found correlations between hydrocarbon emissions and particulate data. The hydrocarbon concentration was evaluated from measurements with two gas sensors: an exothermicity sensor for reducing gases and a novel hydrogen sensor, both installed in the flue gas.
