In many industrial applications such as drying, pelletizing, textile finishing, food processing, and ventilation systems, a large amount of high-temperature exhaust gas is discharged continuously during operation. This exhaust gas contains valuable sensible heat, which is often released directly into the atmosphere, resulting in significant energy waste and high operating costs.
The Exhaust Gas Heat Recovery System is designed to capture and reuse this wasted heat, improving overall energy efficiency and reducing fuel and electricity consumption.
The system is built around a plate-type air-to-air heat exchanger core. High-temperature exhaust gas and fresh intake air flow through separate and fully isolated channels within the heat exchanger. Heat is transferred through the plates without any mixing of air streams, ensuring clean operation and preventing odor, moisture, or contaminant carryover.
Recovered heat is used to preheat fresh air supplied back into the production process, such as drying chambers, pellet coolers, or make-up air systems. By increasing the inlet air temperature, the load on heaters, burners, or steam systems is significantly reduced, leading to lower energy consumption and operating costs.
The plate heat exchanger core features a compact structure, large heat transfer surface, and low air resistance, making it suitable for continuous industrial operation. The system also helps reduce exhaust gas temperature and humidity, easing the burden on downstream cooling, deodorization, or dehumidification equipment.
One of the key advantages of the Exhaust Gas Heat Recovery System is its low operating cost. No additional heating or cooling energy is required, and power consumption is mainly limited to fans. The modular design allows flexible configuration according to air volume, temperature, and process requirements, making the system suitable for both new installations and retrofit projects.
By recovering waste heat that would otherwise be lost, the Exhaust Gas Heat Recovery System provides a practical solution for energy saving, cost reduction, and sustainable industrial operation, while maintaining stable process performance and improved working environments.
