Technology Advancements in Air & Gas Flow Measurement in Thermal Power Plants

Power generation worldwide is on topmost priority for sustaining domestic and industrial growth. With the advancement in coal-based thermal power plant technologies & stricter environmental emission norms, efficient controls of combustion & emission controls are of utmost importance.

Efficient operation of the thermal power plants depends largely upon accurate and repeatable measurement of primary and secondary airflow to coal mills, flue gas recirculation flow, overfire airflow, airflow to individual burners, and flue gas emission rate.

Flue gas flow measurement is a challenging task having mixtures of O2, CO2, CO, SPM, SOx, NOx, HC, etc. & large diameter ducts where conventional flow measurements are unreliable, non-repeatable, high maintenance prone & expensive.
