NOx sensors are widely used in power plants to monitor and control nitrogen oxide emissions, which are a major contributor to air pollution and environmental damage. In power plants, NOx sensors are commonly used in gas turbines, diesel engines, and coal-fired boilers.

The NOx sensors used in power plants work in a similar way to those used in other combustion sources. They continuously monitor the levels of NOx emissions in the flue gas and send the readings to the plant’s control system. The control system then adjusts the combustion process, such as fuel injection, air-to-fuel ratio, and other factors, to minimize NOx emissions.

In power plants, NOx sensors must operate in harsh environmental conditions, such as high temperatures and corrosive gases. To meet these challenges, manufacturers have developed advanced NOx sensors using materials and technology that are suitable for power plant applications. For example, some NOx sensors use ceramic materials that can withstand high temperatures and extreme conditions.

The use of NOx sensors in power plants has become increasingly important due to stringent environmental regulations and emission standards. By monitoring NOx emissions and optimizing combustion processes, power plants can achieve compliance with regulations and reduce the environmental impact of their operations.
