Combustion Turbines NOx Sensor

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.

Gas Turbine Types and NOx Monitoring

Gas turbines are widely used in power generation, oil and gas processing, and industrial applications. NOx emissions from gas turbines are a significant environmental concern, and accurate monitoring is essential for regulatory compliance and operational optimization.

Heavy-Duty Power Generation

Large gas turbines used in power plants (50-500+ MW) are subject to strict NOx emission limits. These turbines often operate continuously, requiring sensors with exceptional long-term stability and minimal drift. Our sensors are designed for the demanding conditions of power generation exhaust streams.

Aeroderivative Turbines

Derived from aviation engines, aeroderivative turbines offer high efficiency and fast start-up times. They are commonly used in peaking power plants, offshore platforms, and industrial cogeneration. NOx sensors for these applications must handle rapid load changes.

Industrial Cogeneration

Combined heat and power (CHP) systems using gas turbines need precise NOx monitoring to optimize the balance between electrical output, heat recovery, and emission compliance. Our sensors support continuous emission monitoring (CEM) systems in these facilities.

Oil & Gas Processing

Gas turbines drive compressors and generators in oil and gas facilities. These applications often involve fuel gas with varying compositions, which affects NOx formation. Our sensors provide accurate readings regardless of fuel gas variations.

Industrial Use Cases

Continuous Emission Monitoring (CEM)
Power plants and industrial facilities use continuous monitoring systems to track NOx emissions in real-time. Our sensors integrate with standard CEM systems.

SCR System Control
Selective Catalytic Reduction systems use NOx sensor feedback to optimize urea/ammonia injection, reducing emissions while minimizing reagent consumption.

Performance Optimization
Real-time NOx data helps operators tune combustion parameters for optimal efficiency while staying within emission limits.

Environmental Compliance
Regulatory bodies worldwide require documented proof of emission compliance. Our sensors provide the accurate data needed for reporting.

Whether you operate a single industrial turbine or manage multiple power generation facilities, our NOx sensors deliver the accuracy, reliability, and longevity you need to maintain compliance and optimize performance.
