RTO with Heat Recovery Unexpected Issues

RTO with Heat Recovery

Introduction

Regenerative Thermal Oxidizer (RTO) with heat recovery is an effective and popular approach for industrial air pollution control. However, despite its advantages, unexpected issues can arise during its operation. This article aims to explore and explain in detail the problems that can occur with RTO with heat recovery and how to address them.

Heat Recovery Efficiency Reduction

Thermal energy loss due to leakage and insufficient insulation
Inadequate maintenance of the heat exchanger
Contamination of the heat exchanger by the process air stream
Solution: Regular inspection and maintenance, including cleaning, repairing, and replacing the heat exchanger and insulation materials

Corrosion and Scaling of the Heat Exchanger

Prolonged exposure to high-temperature gases and moisture
Chemical reactions and deposits on the heat exchanger surface
Material degradation and mechanical failure
Solution: Selecting appropriate heat exchanger materials and coatings, implementing proper cooling methods, monitoring and controlling the process gas composition and heat exchanger condition regularly

Carbon Monoxide (CO) and Volatile Organic Compounds (VOCs) Emissions

Incomplete combustion due to insufficient oxygen supply, low temperature, or short residence time
Malfunction of the burner, valves, or controls
High VOCs concentration or unstable composition
Solution: Optimizing the combustion conditions, adjusting the air-to-fuel ratio, maintaining and upgrading the combustion system, controlling the VOCs source and composition, installing additional emissions control devices if necessary

Excessive Pressure Drop and Fan Overload

High resistance and clogging of the heat recovery media
Defective fan or motor, improper fan speed or size
System overloading and imbalanced airflows
Solution: Monitoring and cleaning the heat recovery media regularly, replacing damaged or ineffective media, selecting suitable fans and motors, balancing the airflows and pressure drops, optimizing the ductwork and stack design

Electrical and Instrumentation Failures

Wiring problems, grounding errors, and power surges
Faulty sensors, transmitters, and controls
Human errors and insufficient training
Solution: Conducting regular electrical and instrumentation inspections and maintenance, testing and calibrating the sensors and controls, providing adequate training and safety procedures

Odor and Noise Pollution

Inadequate odor control and ventilation
Excessive noise from the combustion, fan, or process equipment
Unacceptable impact on the neighboring community
Solution: Installing and maintaining odor control devices such as carbon adsorption, biological treatment, or thermal oxidizers, monitoring and enforcing the noise regulations and standards, communicating and addressing the concerns of the community

Conclusion

Regenerative Thermal Oxidizer with heat recovery is a reliable and efficient technology for air pollution control in industrial processes. However, various unexpected issues can arise during its operation, which requires proper monitoring, maintenance, and troubleshooting. By addressing the common problems of RTO with heat recovery, we can improve its performance, safety, and environmental impact, and ensure the compliance with the regulatory requirements.
