Technical Field

[0002] Electric heating RTO (Regenerative Thermal Oxidizer) purification is a method for waste gas treatment and air pollutant purification using electric heating technology. It is a variant of the RTO system that uses electric heating elements instead of traditional burners to provide high-temperature oxidation conditions. The ceramic regenerators used in the RTO purification process are usually key components, which are used for heat recovery and thermal energy utilization. The ceramic regenerators have high heat capacity and thermal conductivity, can absorb the thermal energy in the waste gas, and release heat during the cycle reversal process to preheat the fresh waste gas.
