What is the RTO system?

A regenerative thermal oxidizer (RTO) is a thermal oxidizer that uses a bed of heat-retentive media to preheat the combustion air. This process significantly reduces the fuel required to operate the thermal oxidizer and the number of pollutants emitted into the atmosphere. RTO systems are commonly used to destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and odorous compounds.

What are the requirements for the RTO system?

rto system

To operate an RTO system, the following requirements must be met:

  1. The system must be equipped with an oxidation chamber lined with a material that can withstand high temperatures.
  2. The system must have a means of heating the chamber to the operating temperature, typically between 750 and 950 degrees Fahrenheit.
  3. The system must have a means of introducing the waste stream into the chamber.
  4. The system must have a means of removing the resulting exhaust stream from the chamber.
  5. The system must have a means of recirculating the exhaust stream through the chamber to promote contact between the waste stream and the chamber walls.


How can the RTO system be used in the industry?

RTO system can be used in industries where processes generate pollutants in the form of gas or vapor. RTO works by passing the contaminated gas stream through a chamber where it is heated to a high temperature. This causes the pollutants to be oxidized, or burned off, leaving clean air to be discharged into the atmosphere. RTO system is a highly effective pollution control technology that can achieve up to 99% removal efficiency of a wide range of pollutants.

What are the challenges of the RTO system?

There are several challenges associated with regenerative thermal oxidizers (RTOs). One challenge is the potential for thermal runaway, which can occur when the system’s combustion chamber temperature gets too high. This can damage the system and potentially cause an explosion. Another challenge is the potential for fouling the system’s heat exchanger, which can reduce its efficiency and cause it to overheat. Additionally, RTO systems can be expensive to operate and maintain, requiring a significant amount of energy to work.

Are there any alternatives to using the RTO system?

regenerative thermal oxidation system

There are a few alternatives to using RTO systems, depending on the application. One common alternative is a thermal oxidizer, which uses a combustion chamber to oxidize waste gases at high temperatures. This is typically used for applications where the waste gas stream is not very dirty or where the contaminants are not very volatile. Another alternative is a catalytic oxidizer, which uses a catalyst to promote the oxidation of waste gases at lower temperatures. Again, this is often used for applications where the waste gas stream is very dirty or where the contaminants are very volatile.


Regenerative thermal oxidizers efficiency, how they work and benefits of use

Regenerative thermal oxidizers, or simply RTO, are a type of air pollution management equipment. They clean the air and eliminate hazardous air pollutants, odorous emissions and combustible organic compounds formed during industrial processes. These are often a byproduct of paint shop coating machines. As a leading regenerative thermal oxidizer manufacturer we produce air cleaning devices […]

Why thermal oxidisers are important for industrial applications

How thermal oxidisers work in general? A thermal oxidizer is a type of industrial pollution control device that is used to remove volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from an air stream. Thermal oxidizers work by using heat to oxidize, or break down, VOCs and HAPs into less harmful compounds. What is […]
