How efficient is a regenerative oxidizer?

Regenerative thermal oxidizers have a heat recovery (efficiency) of 95% typically. This technology has the lowest operating cost of all thermal oxidizer systems – not to mention the longest service life and highest reliability. It’s even possible for an RTO to operate with no auxiliary fuel use whatsoever if process VOC concentration levels are >3-4% lower flammability limit (LFL).

What does regenerative mean?

The term “regenerative” in regenerative thermal oxidizer is drawn from the type of ceramic media heat exchanger used in these systems. It is unique in that it captures heat from the exhausting, clean airstream during one cycle and releases the heat to the incoming, dirty airstream in the next cycle. The heat is captured (and released) from beds of ceramic media. The RTO incorporates switching valves to cycle the direction of the airflow through the RTO heat exchanger beds to enable regenerative heat recovery.

Would an induced draft fan be a better choice than a forced draft fan?

We have hot spots on the outside of our RTO. Can you fix this?

Yes we have a team of experienced fabricators and insulators we can bring in to repair your oxidizer. Damaged metal may have to be replaced to ensure a secure surface is available to weld the insulation modules to.

We are buying a new piece of process equipment. Do we have capacity in our existing oxidizer or can we make changes to achieve the needed capacity?

We can evaluate the existing oxidizer capacity and the requirements of the new process and determine the best approach to upgrade the oxidizer. This could include new heat exchanger media, a larger fan or possibly both. We would also evaluate things like the burner system and combustion chamber size to verify it can provide the required destruction levels. Some applications would be a good match for a VOC concentrator that can significantly concentrate (>10:1) airstreams currently exhausting to the oxidizer.
