We have ZR22G-100-S-A-E-T-T--E-A/CV/F1 Model Zirconia
Oxygen analyser which is Yokogawa make. I kept the analyser
in Flue gas path at Air pre heater area. My plant is 7.5MW
Biomass power plant. For a particular fuel, Coconut Husk
which contains Sodium and Potassium chlorides iam not
getting proper reading, Analyser output always Zero. I
calibrated the analyser and it is OK. For Other fuels like
Wood chips, Cholam waste, DOB, Groundnutshells, Ply wood
waste and all iam getting actual percentage of Oxygen. What
is the main reason behind this draw back?
