Demand for Low NOx Burners and SCR Systems Boosts Global Nitrogen Oxide Control System Market

Global Nitrogen Oxide Control System Market Grows at 5.4% CAGR, Driven by Clean Air Initiatives

WILMINGTON, DE, UNITED STATES, October 30, 2025 /EINPresswire.com/ --

According to a new report published by Allied Market Research, the global nitrogen oxide control system market size was valued at $4.3 billion in 2020 and is projected to reach $7.3 billion by 2030, growing at a CAGR of 5.4% from 2021 to 2030.

Nitrogen oxide (NOx) is a major air pollutant formed when fossil fuels such as coal, oil, gas, and diesel are burned at high temperatures. These emissions contribute to air quality degradation, ozone formation, and respiratory problems, prompting global efforts to control NOx output. As governments tighten environmental regulations, the nitrogen oxide control system market is witnessing steady growth across industrial and transportation sectors.

🌱 Key Market Drivers

🔹 Environmental Regulations

Governments worldwide are implementing stringent air quality standards to combat pollution and meet sustainability targets. Regulatory agencies such as the EPA and EU Commission are enforcing emission limits on power plants and industrial facilities, which boosts demand for NOx control technologies.

🔹 Transition Toward Clean Energy

As industries shift from fossil fuels toward cleaner energy, they are adopting retrofit and replacement solutions like SCR and LNB systems to comply with green standards while maintaining energy efficiency.

🔹 Industrial Expansion

The ongoing industrial boom in Asia-Pacific, coupled with modernization of power plants and refineries, has created lucrative opportunities for nitrogen oxide control system manufacturers.

⚗️ Understanding Nitrogen Oxide and Its Impact

NOx is a mixture of nitrogen and oxygen compounds, primarily nitrogen dioxide (NO₂), which contributes to smog and particulate pollution. It is one of six widespread pollutants regulated under national air quality standards in the U.S. and other regions.

Common emission sources include cars, trucks, buses, power plants, diesel engines, and industrial boilers. In 2019 alone, human activities released nearly 18 million metric tons of nitrogen oxides in the U.S. However, due to cleaner technologies and tighter standards, emissions are expected to decline further over the next decade.

Exposure to nitrogen dioxide can inflame the lungs, trigger asthma attacks, and reduce lung function, making NOx control essential for both environmental and public health.

⚙️ Control Strategies and Technologies

Effective control of NOx emissions involves two key categories:

Stationary sources (like power plants and industrial boilers)

Mobile sources (like vehicles and construction equipment)

The report focuses primarily on stationary source control technologies, which are critical for large-scale emission reduction. Major nitrogen oxide control system technologies include:

Low NOx Burners (LNB): Reduce NOx formation during combustion.

Selective Catalytic Reduction (SCR): Converts NOx into nitrogen and water using ammonia.

Selective Non-Catalytic Reduction (SNCR): Reduces NOx without catalysts, ideal for smaller systems.

Fuel Reburning: Introduces secondary fuel to reduce NOx formation.

Flue Gas Recirculation (FGR): Lowers flame temperature to reduce emissions.

Staged Combustion & Process Modification: Controls combustion temperature and oxygen levels.

Among these, Low NOx Burners emerged as the dominant technology in 2020, offering cost-effective NOx reduction for industrial and power generation applications.
