Use of zirconium oxide oxygen probes in the incineration industry
CarboProbe HT oxygen probe developed for incinerators
Zirconium oxide oxygen probes play a key role in the incineration industry, particularly for measuring the oxygen content (%O2) in flue gases. These advanced tools help ensure optimal combustion, guaranteeing safe, efficient operation that complies with environmental standards.
Operating principle
Oxygen probes work by measuring the oxygen content of combustion gases. They use a sample of clean, dry reference air injected into an internal reference chamber. This air is called “reference air”. This air flow guarantees a stable and constant basis for comparing the concentration of oxygen present in combustion gases.
Zirconium oxide, the probe’s main material, becomes an ion conductor at high temperatures (from 600°C). A difference in oxygen concentration between the reference air and the measured gases creates an electrical potential. This signal is then interpreted to determine the precise oxygen content (%O2). In the incineration industry, this level must generally be maintained between 46% and 10% to ensure efficient combustion and limit pollutant emissions.

Concrete example of use
In a meat waste incineration plant, Econox probes are used to continuously monitor oxygen levels in flue gases. Here’s how it works:
Initial phase
The incinerator is heated to a high operating temperature. The probe continuously measures oxygen levels to ensure that they remain within the optimum range of 6% to 10%.
During incineration
Sensors detect variations in oxygen levels and transmit this information to the control system, which automatically adjusts the air supply to maintain efficient combustion.
Result
Complete combustion is achieved, reducing residual waste and minimizing CO and fine particle emissions.
