WORKING PRINCIPAL OF O2 ANALYZER || IN STEAM BOILER HOW TO CALCULATE OXYGEN IN FLUE GAS PATH.

An oxygen analyzer measures the para-magnetism of air. ... The air being measured for oxygen is filtered by passing it through a diffuser before. Then it is passed through the two chambers. One chamber attracts oxygen via its magnetic field, while the other chamber attracts air.Accurate calibration is obtained by using pure nitrogen for zero and normal air for setting the span at 21% oxygen. False readings are obtained if the gas being sampled contains another para-magnetic gas.Cleaning O2 Sensor/Catalytic Converter. ... There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors. more video for BOILER OPERATION AND BOE EXAM PREPARATION    • BOILER Operations And BOE exam Preparation   for FITTER, TURNER, WELDER, MACHINIST THEORY IMPORTANT TOPICS AND OBJECTIVES QUESTION AND ANSWER    • Fitter theory and MCQ online      • FITTER MCQ
