Application Case

In October 2013, the technology was successfully implemented at Laigang Section Steel Company’s Ironmaking Plant, where three sintering machines were equipped with the system. The recovered low-temperature flue gas heat is transferred through specially designed heat exchangers to produce 80 ℃ hot water, which is then supplied to the production area for winter heating.

Results and Benefits

• Heating Area: 180,000 ㎡ of production facilities

• Hot Water Supply: 80 ℃ water generated continuously from waste heat

• Economic Savings: Annual steam-saving benefits exceeding RMB 10 million during the heating season

• Sustainability: Significant contribution to energy conservation and emission reduction in steel production

Technology Development

BOOYO Industry, in collaboration with Shandong Metallurgical Design Institute and the leadership of Laigang Ironmaking Plant, developed an innovative non-power flue gas heat recovery technology. Unlike conventional methods requiring additional energy input, this system utilizes the residual pressure of the cooler fans to recover heat without external power, significantly improving efficiency and sustainability.

Conclusion

The successful application of BOOYO Industry’s non-power flue gas heat recovery technology demonstrates its practical value and scalability in the steel industry. By turning waste heat into a reliable energy source, the technology not only reduces operating costs but also aligns with global sustainability goals.
