Operational Principle

The RCO furnace consists of a heat storage tank and an oxidation tank. The heat storage tank is filled with high-temperature resistant ceramic, which can store the energy released from cooling high-temperature flue gas, used to preheat the incoming exhaust gas. The VOCs-containing exhaust gas is gradually heated as it moves from the heat storage tank to the oxidation tank. A catalyst is placed on top of the ceramic layer in the heat storage tank. Under its catalytic action, the exhaust gas is decomposed into CO₂ and H₂O in the oxidation tank, releasing a significant amount of heat energy. The purified high-temperature flue gas, after passing through the heat storage tank on the other side, stores the heat in the ceramic layer, which is used to preheat the exhaust gas for the next cycle. Due to the lower temperature of the catalytic oxidation reaction, the combination of the catalyst layer and the ceramic in the RTO significantly reduces the fuel required for the preheating process and the oxidation reaction of the exhaust gas, further reducing carbon emissions and the operating costs of the incinerator.

Applicable Scope

1. Low concentration VOCs waste gas.

2. The waste gas to be treated can be the process waste gas that can be removed by catalysis.

3. The waste gas does not contain substances that are easy to cause catalyst poisoning.

Characteristic

1.RCO furnace heating heat source can be selected from oil, gas, electricity and other ways.

2. Compared with other oxidation processes, energy consumption is significantly reduced.

3. Flexible design that can be converted to RTO operation.

4. Low nitrogen oxide emissions.

5. The equipment size can be customized according to the floor area provided by the owner.
