Knowledge of the local velocity or the velocity field of flue gas is of interest for technical (heat transfer, attrition, degree of fuel utilization) and economical optimization of combustion facilities. A high temperature anemometer (HTA) was developed to measure gas velocity under extreme conditions. The HTA can be combined with a fast oxygen sensor. This combined sensor provides a rugged and simple to use measuring device, which enables the simultaneous measurement of the local gas velocity and oxygen concentration.
