Large Volume of Stable Heat
Mine drainage features a large water volume and relatively stable temperature. The Mine Drainage Heat Recovery Unit captures heat from this drainage and uses it as a heat source for heat pump systems. The drainage temperature typically ranges from 18℃ to 30℃, making it an excellent low-temperature heat source. The drainage flow rate ranges from 50 to 1000 cubic meters per hour. The equipment fully utilizes this abundant thermal resource.
High Recovery Capacity
The waste heat recovery efficiency is over 70%. The heat pump COP ranges from 4.0 to 5.5. The outlet water temperature is 45℃ to 55℃. The system includes automatic filtration and descaling for mine drainage treatment.
The heat recovery capacity ranges from 100 kW to 5000 kW. This level of output is sufficient for applications such as shaft freeze protection and building heating. The Mine Drainage Heat Recovery Unit enables large-scale heating through waste heat utilization.
Key Advantages and Stable Heat Source
The key advantage of mine drainage heat recovery is the stability and abundance of the heat source. Drainage is a continuous byproduct of mining operations and flows every day, while the associated heat is typically wasted.
By recovering this heat, operational heating costs can be significantly reduced. We have been in business since 1996 and have extensive experience in water-source heat pump systems. Our heat exchangers are designed with anti-clogging and anti-corrosion features to suit the water quality characteristics of mine drainage.
We have completed similar projects for Zijin Mining, with excellent performance results. The Mine Drainage Heat Recovery Unit is a proven and reliable solution in real-world applications.
