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?
