Pollution Control
Thermal Oxidizer
Our client has an RTO on its aluminum window frame painting line, and we supplied a total hydrocarbon analyzer to meet compliance. We get a huge spike in the readings when the RTO chambers cycle every four minutes. We can go from 3 to 6 ppm for four min, then spike to 400 to 1,000 ppm for a few seconds. I don’t believe RTOs should work that way and that switching should have little or no effect on efficiency. I think the client’s unburned paint is contaminating our gas analyzer.
