Answer / Mukesh Pandey

An oxygen (O2) sensor is used in a boiler stack to monitor the combustion efficiency and exhaust gas composition. By measuring the percentage of O2 in the flue gases, the sensor helps ensure optimal fuel-air mixing, preventing excessive fuel consumption or harmful emissions. It also helps maintain a safe and stable operating environment within the boiler.
