Abstract: The flue gas monitoring plays a vital role in thermal power plants as these emissions contribute to the majority of air pollution and global warming. This project proposed to measure concentration method for flue gas of multiple fuels such as natural gas, coal, oil etc based on NDIR & Electrochemical Sensors. Efficiency of power plants becomes more important due to the demand for cost-efficient energy production & tightening environmental regulations. The main objective of the project is to increase the performance of the plant and to protect the environment, thereby giving a pollution free environment for the future generation. The Flue Gas Analyzer measures the amount of Oxygen, combustible gases such as Carbon Monoxide, Carbon Dioxide, Nitrogen Oxides and Sulfur Oxides in the flue with the help of electrochemical Sensors. The measured values of flue gases that are displayed are then compared with their permissible limits.
