YSZ-based underfiring sensor for simultaneous measurement of residual oxygen and unburnt species in flue gases

Abstract

Flue gas analysis is essential for optimizing combustion efficiency, reducing fuel costs, and ensuring safety by detecting dangerous emissions like carbon monoxide. An amperometric YSZ-based sensor for simultaneous measurement of the concentrations of residual oxygen and unburnt species (CO, H₂) in flue gases has been developed. The sensor has a simple structure and is easy to fabricate, providing a cost-effective solution. It demonstrates high sensitivity, good reproducibility and acceptable response time. The use of the sensor for the in-situ real-time analysis of flue gas will facilitate the optimization of air-fuel ratios, thereby preventing fuel wastage and hazardous emissions.
