Enhancing Steel Production with Innovative Cooling Solutions
Jiangsu Yonggang Group, a prominent private steel enterprise in China, has been a leader in the industry since its establishment in 1984. With an annual production capacity of 9 million tons, the company continuously seeks innovative solutions to enhance efficiency and sustainability in its operations.
Addressing High Humidity Challenges with BROAD Absorption Chillers
Located in a coastal region with high humidity levels, Jiangsu Yonggang Group faced significant challenges in maintaining optimal operational efficiency. To combat these issues, the company implemented three BROAD BS600 absorption chillers, utilizing residual steam to dehumidify blast air for its three blast furnaces. This strategic approach has led to substantial improvements in energy consumption and environmental sustainability.
Significant Carbon Reduction and Energy Savings
The integration of BROAD absorption chillers has resulted in remarkable environmental and economic benefits:
- Annual Standard Coal Savings: 13,976 tons
- Annual CO2 Emission Reduction: 34,843 tons
- Equivalent Tree Planting Impact: 1,903,964 trees
These figures highlight the significant contribution of BROAD’s advanced dehumidification technology in reducing carbon footprints and promoting eco-friendly industrial practices.
Operational Benefits of Dehumidification in Blast Furnaces
Through the effective dehumidification of blower air, Jiangsu Yonggang Group has achieved notable improvements in blast furnace efficiency:
- Blower dehumidification amount: 7.4g/kg of dry air
- Reduction in blast furnace coke ratio: 8.2%
- Increase in coal injection amount: 1.3%
- Reduction in blower energy consumption: 7.4%
These enhancements have led to increased fuel efficiency, optimized resource utilization, and a more sustainable steel production process.
Conclusion: A Model for Sustainable Industrial Innovation
Jiangsu Yonggang Group’s adoption of BROAD absorption chillers serves as a benchmark for industrial sustainability and efficiency. By leveraging waste heat for dehumidification, the company not only reduces operational costs but also significantly lowers its environmental impact. This case study exemplifies how advanced technology can drive sustainable progress in the steel industry, setting a precedent for future innovations.
For industries looking to optimize energy usage and reduce carbon emissions, BROAD’s absorption chiller solutions offer a proven and effective strategy for achieving long-term sustainability goals.
