NOx sensors or analyzers are essential components in the combustion process of gas-fired combustion turbines, which are commonly used in power generation and industrial applications. They measure the concentration of NOx in the exhaust gases, which allows for continuous monitoring and control of NOx emissions, and compliance with environmental regulations.

The NOx sensors used in combustion turbines can be categorized into two types: in-situ and extractive. In-situ NOx sensors measure NOx concentrations directly in the engine combustor, while extractive NOx sensors collect a sample of the exhaust gases and measure NOx concentrations outside the engine.

Some common OE part numbers for NOx sensors used in combustion turbines include ABB 10A4000, Siemens 7MB2121, and GE B030805001D. The specific application and OE part number for the NOx sensor will depend on the manufacturer and model of the combustion turbine.

Overall, NOx sensors are crucial for ensuring efficient combustion and reducing NOx emissions in combustion turbines, supporting sustainability and compliance with environmental regulations.
