Currently, there are two technologies in waste treatment equipment: RTO and RCO, which are widely applied. Of course, there are some differences between them. Today, we will discuss these for you.
RTO, or Regenerative Thermal Oxidation technology, utilizes a novel non-steady-state heat transfer method to recover and utilize heat. The principle involves heating organic industrial waste gases to above 760°C, oxidizing VOCs within the waste gases into CO2 and H2O. The high-temperature gas produced during the oxidation process passes through specially designed ceramic regenerative beds, heating the ceramics and storing the heat. This stored heat is then used to preheat and further process organic waste gases, thereby saving fuel resources for waste gas temperature increase. RTO technology is primarily suitable for treating waste gases with medium to low concentrations (100-3500 mg/m³), achieving decomposition efficiency of 95%-99%.
Rco refers to regenerative catalytic combustion. The reaction principle of Rco is: the first step is the adsorption of volatile organic compound molecules on the catalyst, which increases the concentration of reactants, and the second step is the catalytic oxidation of activation energy, which enhances the reaction rate. With the assistance of the catalyst, organic waste gases can undergo anaerobic combustion at a lower ignition temperature, and then be decomposed into CO2 and H2O, producing a significant amount of heat. Sometimes, after reaching the ignition temperature, external heating is not required. The reaction temperature ranges from 250 to 400 °C.
Here are the differences between the RTO and RCO technologies shared by Beijing Waste Treatment Equipment Manufacturer.
