Ecopure® RTO – Regenerative Thermal Oxidizer
Ecopure® RTO Air Pollution Control Systems are based on a highly efficient thermal process, which is used to purify exhaust air containing solvents and unpleasant odors. They can achieve a purification level of over 99.8%. The key features of Ecopure® RTO systems are their high thermal efficiency, low-maintenance design, and low operating expenditure.
Operating principle Ecopure® RTO
First of all, the exhaust air to be treated flows through the hot thermal accumulator in the heat exchanger from the bottom to the top, where it almost reaches the combustion chamber temperature. A large proportion of the hydrocarbons are oxidized at this stage. In the combustion chamber of the Ecopure® RTO, the exhaust air is heated to the reaction temperature of 800°C which is required for complete conversion. If necessary, a burner is used for this purpose. This allows the pollutants to be fully converted into harmless substances. The clean, hot gas then flows through another part of the thermal accumulator from the top to the bottom, where the heat is extracted from it. After this, the clean air is discharged from the system.
Ecopure® RTO systems supplied by Dürr use less primary energy than conventional air pollution control systems, because they have a regenerative heat exchanger consisting of a ceramic thermal accumulator. A highly efficient process uses the energy in the hot exhaust gases to pre-heat the exhaust air that is being treated.
As a result of its high internal heat recovery rate, where the concentration of pollutants is above approximately 1.5 g/Nm3, the system operates in autothermal mode. This means that the energy in the pollutants is sufficient to run the system without additional fuel (for example natural gas).
