What is a thermal oxidizer? | A walk-through of the process from Pollution Systems - Video

Pollution Systems is the industry on expert on thermal oxidizers. This video provides a detailed explanation of how thermal oxidizers work and their various applications.

Video Transcription:
Effective air pollution control systems are essential and required in today’s industrial landscape. Organizations are obligated to keep their facility in compliance with current regulations and to continually seek opportunities to reduce their environmental impact.

Pollutants like VOC’s, or volatile organic compounds, are emission issues that must be treated before being released to the earth’s atmosphere, and a common method to treat VOC’s is the use of a Thermal Oxidizer.

What are thermal oxidizers?

Thermal Oxidations can be simply broken down to a burner in a box

We heat up the VOC’s to a set point temperature, and oxidize or burn them. We are breaking down the VOC’s to CO2 and water. Things that are acceptable going out the stack.

When do I need a Thermal Oxidizer?

Thermal Oxidizers work well with applications where particulates may be present or have higher concentrations of VOC’s. Also known as a fume incinerator, a Thermal Oxidizer, when designed properly, will treat a wide variety of process flow rates and VOC concentrations emitted from a facility.

How does the thermal oxidization process work?

It all starts with the chamber, which houses the heating element to burn the VOC’s. The chamber is heated to a set point temperature of approximately 1,500 degrees farenheit.

Once the set point temperature is reached, the fumes are brought into the chamber through a system fan.

All VOC’s present are oxidized and are broken down into carbon dioxide and water vapor, which carry through the system and out the stack into the earth’s atmosphere.

Thermal Oxidizers are very effective, with a greater than 99% destruction rate, however they are not as thermally efficient as alternatives.

In a straight thermal oxidizer, if I set it at 1,500, what goes out the stack is 1,500. Now people want energy efficiency. Instead of sending 1,500 out the stack, we can put a heat exchanger. And that’s where you have a recuperative thermal oxidizer.
