Thermal oxidizers: which one is better?

With the advent of stricter environmental restrictions, a clean air solution that has emerged as the most sought after or written about is recuperative thermal oxidizers as well as regenerative.
However, do we really know how they are different from each other?

Let us chart the difference between these two oxidizers and their respective advantages.

Design

Recuperative oxidizer, as the name implies, recovers heat from the combustion of the hazardous gases. The primary thermal oxidizers did not have recovery stage and what all they did was decomposing half-burnt gases by exposing them to the high temperatures. However, designers came with modern oxidizers that make use of the heat produced by the combustion of gases for other purposes in a plant as well efficiently use the heat for decomposition of gases. Recuperative design has a couple of heat exchangers in the form of pipes and shells, which recovers the excessive energy and sends it to the plant.


Whereas the regenerative design has a ceramic bed that acts as a heat exchanger, the design makes it more efficient at recovering heat, and that is why it is named regenerative. The exhaust gases are pre heated as they move over the heated ceramic bed, and is partially oxidized, and then it enters the center of the unit, which has combustion center. In the chamber, a fuel is used to increase the temperature further high, so the gases are combusted completely.

Advantages of recuperative oxidizer

•    This design needs lower amount of fuel for combustion
•    The system has catalyst that destroys carbon monoxide in the waste stream
•    It has lower oxides of nitrogen emissions than regenerative

Advantages of RTO

•    Lower fuel requirement than traditional oxidizer, however, larger than recuperative design
•    Not much susceptible to chlorinated compounds
•    High-temperature efficiency

Both of these designs, evidently, have their own sets of advantages; therefore, choosing which design will work better under certain conditions require further analysis. Meet a supplier to understand to know details.
