Zirconium oxide Oxygen probes for continuous measurement of
O2-residue concentration in waste gas
Technical data
Standard length: 1000 mm
Diameter: 25 mm protection tube
Probe voltage: -10 ... 1000 mV
Thermo voltage: thermocouple type B
Measuring range: 0,0 ... 80,0 % O2
Operation temperature: 700 °C ... 1.500 °C
Measuring place: regenerator crown or waste gas channel, vertical position

Benefit
  • Economical use of energy by controlled low excess air: approx. 1,5 % energy saving potential, depending on conditions (in a combination with STG Lambda Control)
  • Controlled reliable near stoichiometric operation with O2 residue concentrations below 1 %, as requirement to reduce the NOX emission
  • Monitoring and control of air infiltration, e.g. reversal leakages, ingressed air
  • Monitoring and compensation of CO Peaks after reversal
  • Important: About 2 … 10% of combustion air results form uncontrolled air ingress, which is not detected by combustion air flow measurement!
