Abstract

A laser spectroscopic oxygen sensor aiming at combustion optimization is developed. The sensor allows for self-monitored operation and has a response time of 300 ms. The accuracy for the oxygen concentration is better than ±0.2 vol%. The laser optical sensor is inherently calibration-free and does not age compared to the conventional ZrO₂ probes. The spectroscopic oxygen sensor is based on a diffuse reflective geometry, which minimizes possible optical interference and also alignment problems caused by the thermal cycles of the furnace and an efficient evaluation algorithm that allows for long-term stable operation.
