Continuous Monitoring of Flue Gas Using Oxygen Analyzer

The hot strip mill at Tata Steel Jamshedpur has three furnaces. Fce #1 and #2 are recuperative types and Fce#3 is regenerative type. Manual gas sampling of flue gas to check for oxygen % took place from the recuperative zones of Fce #1 and #2, which were prone to hazards and gas exposure. Recuperative zones are in remote locations that are hard to access and prone to gas exposure and burn. It was decided to install a continuous monitoring of oxygen analyzer in the waste gas circuit of reheating furnace. Hazards related to manual sampling have been eliminated.
