How does a regenerative thermal oxidizer work? Basic concepts explained


How does a regenerative thermal oxidizer work ? That is a simple question with a little more complicated answer. A regenerative thermal oxidizer or RTO is a sturdy piece of equipment. It is similar to a simpler thermal incinerator (TO) and helps control air pollution by decomposing volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other solvents in the air. T

he combustion device uses a vapour stream and an oxidizer chamber, which maintain and enhance its efficiency. They also ensure that VO compounds react with oxygen and break down into less harmful and dangerous components. Before releasing them into the air, the harmful emissions are converted into H2O and CO2 with heat. Its efficiency determines how great RTOs work.

A higher percentage number equals better removal rates and better quality. Thermal oxidizers manufacturers produce equipment with high thermal efficiency and incredible VOC and HAP removal rates, which rank between 97% to 99%. Such productivity and effectiveness are an integral part of the:

  • Soil remediation
  • Food industry
  • Process plants
  • Wastewater treatment
  • Chemical industries
  • Process plants

Thermal oxidizer Cost, life span and its components


Thermal oxidizers manufacturers use superb materials to guarantee safe, effective and reliable solutions while complying with necessary regulations. The incinerators are manufactured out of the following components:

  1. Waste feed systems as disentrainment, control valves, water liquid-seal drums, inlet piping with isolation and flame arrester.
  2. Fuel piping trains to the pilot and the burner that include control valves and inlet piping with isolation
  3. Combustion chamber with high-temperature refractory liner
  4. Inlets for air, such as blowers or air dampers
  5. Waste burner, pilot, and assist fuel burner
  6. Flame safety guard, which includes temperature, fuel, over-fire and air controls
  7. Sample ports for measuring and supervision of pollution-control system

Selection of the proper machine for the job starts with the reflection of the process, waste composition, industries and plant needs. Low-cost operating solutions are crucial for air pollution control in chemical plants and processing units. Both machines are a significant investment that depends on size, additions and heat exchange systems. It is essential to choose wisely because a top-notch machine can last up to 20 years. Longevity, however, depends on:

  • Installation location
  • Operating temperature
  • Amount of abrasive particulate
  • Operating hours
  • Start-up and shut-down cycles
  • How corrosive the incoming process gases are

How does a regenerative thermal oxidizer work?

A thermal oxidizer cost – efficient system with a long life span, is a combustion device that works by heating the exhaust fan’s air to incredibly high temperatures. A systems fan forces a polluted airstream through the oxidizer, which must be adequately oxygenated. If it is not, the ambient air is submitted.

Before entering the combustion chamber, the air is preheated by passing through an air-to-air heat exchanger. Incinerating equipment can run with or without an inbuilt heat exchanger, so preheating happens if one is available. Its presence depends on whether the processing plant wants to save money on capital or fuel. Heated air to an appropriate temperature ensures hazardous air pollutants and volatile organic compounds’ devastation.

Typical temperature values are more than 1400°F (760°C) with dwell durations of 0.5 to 1 second. The process happens in the combustion chamber. Air is there heated and maintained at that temperature with turbulence. The results are VOCs and HAPs converted to CO2 and H2O. If equipped, the hot, clean air passes through the heat exchangers, hot pass.

When the air is cooled, it is released into the environment. Thermal oxidizer vs flare? That is one of the predominant questions in the industry. As the two systems differ, it is essential to investigate all the conditions under which they will function. Good research will help you determine the right one for the job.

Thermal oxidizer vs flare – Which one is ideal for your manufacturing plant?


Thermal oxidizers manufacturers will quickly tell you there are immense differences between a TO and a flare. A combustor or an enclosed flare is an air pollution abatement equipment uniquely manufactured to handle high-energy process discharge streams. Compared to traditional flares, there is no visible flame.

Typical destruction efficiency is elevated, but it cannot compare to TOs. Even though they provide acceptable operating costs, they are not as cost-efficient as incinerators. The enormous distinction is enclosement. While TOs are always enclosed, flares can either be open-flame or enclosed. Out of the two TOs have a higher Destruction Rate Efficiency (DRE), but flares are used to treat higher BTU (British Thermal Units ) value gases.

Amongst them are natural processed and unprocessed gasses, mixtures, compressed natural gas, fuel and more. Now that you know how does a regenerative thermal oxidizer work, you will identify the innovative engineering of its components. They were designed and manufactured to conduct long-term, reliable, cost-saving and efficient operations.
