The growth in the historic period can be attributed to stringent environmental regulations, industrial expansion, public awareness, economic growth, and growing awareness among industries.

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 2029 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to ongoing environmental regulations, a rise in industrial activities, global environmental initiatives, and rising investments in green technologies. Major trends in the forecast period include advancements in oxidizer technology, innovations improving efficiency, technological advancements, the integration of IoT, and automated control systems.

Industrial air pollution, stemming from emissions during manufacturing processes such as fossil fuel combustion and chemical reactions, continues to contaminate the atmosphere with harmful substances. This pollution, including particulates and volatile organic compounds (VOCs), contributes to health issues, environmental degradation, and smog. Direct-fired thermal oxidizers play a crucial role in mitigating these effects by efficiently combusting VOCs and hazardous air pollutants emitted by industries. This capability is crucial as industrial air pollution, as reported by the UK's Department for Environment, Food, and Rural Affairs in February 2024, has shown alarming increases in emissions such as PM10 and sulfur dioxide, with notable rises in NMVOC emissions from food and beverage production by 27%. Consequently, the demand for direct-fired thermal oxidizers is expected to rise in response to escalating industrial air pollution.

Leading firms in the direct-fired thermal oxidizer sector are concentrating on modernizing and replacing outdated systems, such as low NOx thermal oxidizers.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.

North America was the largest region in the direct-fired thermal oxidizer market in 2024. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in the direct-fired thermal oxidizer market report are Asia-Pacific, Western Europe, Eastern Europe, North America, South America, Middle East, Africa. The countries covered in the direct-fired thermal oxidizer market report are Australia, Brazil, China, France, Germany, India, Indonesia, Japan, Russia, South Korea, UK, USA, Canada, Italy, Spain.

A direct-fired thermal oxidizer is utilized as pollution control equipment in industrial settings to treat air emissions containing volatile organic compounds (VOCs) and other pollutants. It operates by burning these pollutants directly through a burner system, transforming them into less harmful substances such as carbon dioxide and water vapor before they are released into the atmosphere.

Direct-fired thermal oxidizers come in various capacities, including 180 kW, 400 kW, 600 kW, and others. The 180 kW models are specifically designed for medium-sized industrial applications, effectively combusting organic compounds in emissions through direct flame contact, without employing secondary heat recovery. Pollutants targeted include odors, particulate matter, acids, chlorinated and fluorinated compounds, VOCs, hazardous air pollutants (HAPs), among others. End-use industries benefiting from these systems encompass chemical, pharmaceutical, oil and gas, petrochemical, automotive, and waste management sectors.
