Abstract

This study presents a CO/HC gas sensor designed for operation at high temperatures in harsh environments, such as the flue gas of biomass combustion systems. The sensor principle is based on an indirect thermoelectric effect caused by exothermic reactions, which enables the detection of unburned flue gas components. A special feature of the sensor is its manufacturing process, whereby structured lines of a thermoelectric material are fabricated using the powder aerosol deposition method. As a result, significantly enhanced sensor sensitivity was achieved compared to the conventional sensor design.
