Regenerative Thermal Oxidizer (RTO) uses the ceramic regenerators to store the heat generated by the decomposition of VOCs, and uses the thermal energy stored in the ceramic regenerator to pre-heat and decompose the untreated VOCs, thereby achieving high thermal efficiency.
System structure
1. regenerator
The regenerator is the heat carrier of RTO system, which directly affects the heat utilization rate of RTO. Its main technical indicators are as follows:
(1) heat storage capacity: the larger the heat stored by the unit volume of the regenerator, the smaller the volume of the regenerator;
(2) heat transfer speed: the thermal conductivity of the material can reflect the speed of heat transfer, the greater the thermal conductivity, the faster the heat transfer;
(3) thermal shock stability: the regenerator switches continuously between high and low temperature for many times. Under the condition of huge temperature difference and short time change, it is easy to deform and break, block the air flow channel, and affect the heat storage effect;
(4) corrosion resistance: the gas medium contacted by the heat storage material is mostly highly corrosive, and the corrosion resistance will affect the service life of RTO.
