What are the operating parameters for RTO with heat recovery?

Regenerative Thermal Oxidizers (RTO) with heat recovery are commonly used to treat VOC emissions from industrial processes. For optimal performance, certain operating parameters must be considered and maintained. In this article, we will discuss the key parameters for operating RTOs with heat recovery.

1. Chamber Temperature

The chamber temperature is the most critical parameter for RTO operation as it directly impacts the destruction efficiency of VOCs. The temperature should be maintained at a level that promotes the complete oxidation of VOCs. The ideal operating temperature range for an RTO is typically between 760-820¡ãC (1400-1500¡ãF).

2. Residence Time

The residence time is the length of time that the gases spend in the RTO chamber. This parameter is important because it allows for the proper mixing and oxidation of VOCs. The residence time should be long enough to ensure complete oxidation of the VOCs. Typically, residence times of 0.5 to 1.5 seconds are recommended for RTOs with heat recovery.

3. Airflow Rate

The airflow rate is the volume of gas flow through the RTO chamber. The airflow rate must be sufficient to ensure that the VOCs are fully oxidized. This parameter is typically measured in cubic feet per minute (CFM). The airflow rate should be adjusted to meet the specific process requirements.

4. Heat Exchanger Efficiency

The heat exchanger is responsible for recovering the heat generated during the oxidation process. The efficiency of the heat exchanger affects the overall energy consumption of the RTO. A higher heat exchanger efficiency will result in less energy consumption and lower operating costs.

5. Control System

The control system is responsible for maintaining the operating parameters within the required range. The control system should be equipped with alarms and safety interlocks to prevent hazardous conditions. The control system should be regularly checked and calibrated to maintain proper operation.

6. Maintenance

Routine maintenance of the RTO is critical for optimal performance and longevity. Maintenance tasks include regular cleaning of the heat exchanger, chamber inspection, and replacement of damaged or worn components. A regular maintenance schedule should be established and followed to ensure proper operation.

7. Process Changes

Any changes to the process being treated by the RTO can impact the operating parameters. It is essential to monitor the process and adjust the RTO parameters as needed to ensure proper operation and compliance.

8. Monitoring and Data Logging

Monitoring and data logging are critical for maintaining the RTO’s operating parameters and ensuring compliance with regulatory requirements. The system should be outfitted with sensors and instruments to monitor the temperature, airflow rate, and other critical parameters. A data logging system should be used to record the system’s performance and identify any deviations from normal operation.
