Direct-Fired Thermal Oxidizer Market Report 2026

The direct-fired thermal oxidizer market size has grown strongly in recent years. It will grow from $1.42 billion in 2025 to $1.5 billion in 2026 at a compound annual growth rate (CAGR) of 5.7%. The growth in the historic period can be attributed to rising industrialization, increasing environmental awareness, early regulatory enforcement initiatives, growing manufacturing expansion activities, rising emission related compliance needs.

The direct-fired thermal oxidizer market size is expected to see strong growth in the next few years. It will grow to $1.83 billion in 2030 at a compound annual growth rate (CAGR) of 5.2%. The growth in the forecast period can be attributed to stricter environmental emission regulations, rising focus on sustainable industrial operations, growing demand for efficient pollution mitigation systems, increasing investment in cleaner technology, expanding adoption of advanced emission control infrastructure. Major trends in the forecast period include increasing adoption of advanced emission control systems, growing focus on industrial air pollution reduction, rising installation of high efficiency thermal oxidizers, expansion of pollution control solutions across industries, strengthening emphasis on regulatory compliance technologies.

The increasing industrial air pollution is expected to propel the growth of the direct-fired thermal oxidizer market going forward. Industrial air pollution refers to the contamination of the atmosphere by harmful emissions generated from industrial processes. It arises primarily from manufacturing activities, including the combustion of fossil fuels, chemical reactions, and the release of particulates and volatile organic compounds (VOCs), which contribute to smog formation, health issues, and environmental degradation. Direct-fired thermal oxidizers are widely used in industrial applications to reduce air pollution by efficiently combusting VOCs and hazardous air pollutants (HAPs), thereby minimizing their release into the atmosphere and improving overall air quality. For instance, in March 2025, according to the Department for Environment, Food & Rural Affairs (Defra), a UK-based government body, industrial combustion was a significant contributor to particulate matter emissions in 2023, accounting for 10% of PM2.5 and 5% of PM10 emissions. Therefore, increasing industrial air pollution is driving the growth of the direct-fired thermal oxidizer market.

Leading firms in the direct-fired thermal oxidizer sector are concentrating on modernizing and replacing outdated systems, such as low NOx thermal oxidizers. These systems are designed specifically to minimize the formation and discharge of nitrogen oxides during combustion processes. For instance, in April 2023, Catalytic Products International (CPI), a US-based company specializing in air pollution control equipment, installed a new direct-fired thermal oxidizer at a pharmaceutical manufacturer in Western USA. This installation replaced an obsolete system, ensuring compliance with Clean Air Act standards, Best Available Control Technology (BACT), and low NOx requirements. CPI supplied the 1,000 SCFM QUADRANT NR-1.0 Thermal Oxidizer, achieving a 99% destruction rate efficiency (DRE) for a solvent vapor stream containing various organic solvents.

In May 2023, Xylem Inc., a US-based manufacturer specializing in products and services that address water challenges, acquired Evoqua Water Technologies Corp. for $7.5 billion. Through this acquisition, Xylem Inc. seeks to strengthen its ability to deliver innovative water solutions and tackle global issues related to water scarcity, quality, and resilience. Evoqua Water Technologies Corp. is a US-based technology company that provides direct-fired thermal oxidizers, which effectively treat industrial emissions to ensure environmental compliance and sustainable vapor control.
