Why Exhaust Gas Treatment Equipment Is a Prime Scenario for Waste Heat Recovery
When RTO, RCO, CO, and other organic exhaust gas treatment devices treat VOCs, the inlet exhaust gas often needs to be heated to 760–850°C (RTO) or 300–400°C (catalytic combustion). The treated high-temperature purified gas (300–600°C) is discharged directly, causing huge thermal energy waste. Installing an air-to-air plate heat exchanger before and after the system enables "preheating before treatment and cooling after treatment," saving energy while meeting emission temperature requirements.
