What are the different types of RTOs for air pollution control?

Introduction

Regenerative Thermal Oxidizers (RTOs) are air pollution control devices that are commonly used in industrial processes to remove volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and other air pollutants. RTOs are designed to destroy these pollutants by heating them to high temperatures in a combustion chamber. The hot gases are then directed through a bed of heat-conductive material, which absorbs the heat and preheats the incoming process air. This preheated air is then directed back to the process stream, while the pollutants are destroyed in the combustion chamber.

Types of RTOs

There are a variety of RTO designs, each with its own unique set of features and advantages. Below are the most common types of RTOs used for air pollution control:

1. Single bed RTOs

Single bed RTOs are the simplest type of RTO and consist of a single combustion chamber and heat exchange bed. The process air flows through the heat exchange bed, where it is preheated before entering the combustion chamber. After combustion, the clean air is directed back to the process stream. Single bed RTOs are suitable for low flow rates and low VOC concentrations.

2. Dual chamber RTOs

Dual chamber RTOs are similar to single bed RTOs, but with two combustion chambers and heat exchange beds. The process air flows through the first heat exchange bed, where it is preheated before entering the first combustion chamber. After combustion, the clean air is directed through the second heat exchange bed, where it is further preheated before entering the second combustion chamber. Dual chamber RTOs are suitable for higher flow rates and VOC concentrations.

3. Rotary RTOs

Rotary RTOs are designed with a rotating wheel or drum that contains a heat exchange material. The process air flows through the heat exchange material, which is heated by the exhaust gases from the combustion chamber. The clean air is then directed back to the process stream. Rotary RTOs are suitable for processes with high flow rates and high VOC concentrations.

4. Three-chamber RTOs

Three-chamber RTOs are similar to dual chamber RTOs, but with an additional post-combustion chamber. The process air flows through the first heat exchange bed, where it is preheated before entering the first combustion chamber. After combustion, the clean air is directed through the second heat exchange bed, where it is further preheated before entering the post-combustion chamber for additional destruction of pollutants. Three-chamber RTOs are suitable for very high flow rates and VOC concentrations.

Conclusion

In conclusion, RTOs are an effective and efficient way to control air pollution in industrial processes. There are several different types of RTOs to choose from, each with its own unique set of features and advantages. Single bed RTOs are suitable for low flow rates and low VOC concentrations, while dual chamber RTOs are suitable for higher flow rates and VOC concentrations. Rotary RTOs are suitable for processes with high flow rates and high VOC concentrations, and three-chamber RTOs are suitable for very high flow rates and VOC concentrations. Choosing the right type of RTO depends on the specific needs of the industrial process in question.
