Turn Waste Heat into Useful Energy
The Mine Exhaust Air Waste Heat Recovery Unit is based on heat pump and heat exchange technology. It recovers low-grade thermal energy from mine exhaust air and upgrades it into usable high-grade heat.
The recovered energy can be used for mine shaft heating, building space heating, or domestic hot water production. The exhaust air temperature remains relatively stable between 5°C and 30°C throughout the year, ensuring continuous and reliable operation.
The equipment provides an efficient solution for converting waste energy into usable thermal energy.
High Efficiency Performance
The system achieves a waste heat recovery efficiency of 60%–85%.
Key performance parameters include:
- Air volume range: 50,000–500,000 m³/h
- Heating COP: 3.0–5.0
- Energy conversion ratio: 1 kW electricity input generates 3–5 kW heat output
- Outlet water temperature: 45°C–55°C
- Fan pressure: 150–300 Pa
The system uses either heat pipe exchangers or plate heat exchangers, depending on application requirements.
The Mine Exhaust Air Waste Heat Recovery Unit delivers high-efficiency energy recovery with stable long-term performance.
Key Advantages and Strong Adaptability
The primary advantage of this system is its significant energy-saving performance. Compared with traditional electric heating or fuel boiler systems, operating cost is substantially reduced due to the high COP ratio.
Because mine exhaust air maintains a relatively stable thermal condition throughout the year, the system can operate continuously with high reliability.
In addition, the system is environmentally friendly, with zero direct emissions during operation.
We have been specializing in mining thermal systems since 1996 and hold multiple patents in waste heat recovery technology. The heat exchangers are designed with anti-corrosion and anti-clogging structures, specifically developed to handle the high dust and high humidity conditions of mine exhaust air systems.
This ensures stable operation even under harsh mining environments.
