[Consultation Case] Achieving Energy Savings by Improving the Heat Transfer Rate of Air Heaters
A case where the improvement in heat transfer rate led to a 15% enhancement in heat exchange rate, achieving energy savings.
Here is an example of proposing "Kurita Dropwise Technology" to a steel manufacturing plant. In the company's continuous hot-dip galvanizing line, there is an air heater that uses steam for the drying process after galvanizing, consuming a large amount of steam. They consulted us to find a way to reduce steam usage to achieve energy savings. By applying this technology, the heat transfer rate of the heat exchanger inside the drying air heater improved, leading to a 15% reduction in steam usage. [Case Summary (Partial)] ■ Consultation Details - They wanted to improve operations in the continuous hot-dip galvanizing line. ■ Solution - Application of Kurita Dropwise Technology to impart water-repellent properties to the metal surface and suppress water film formation. *For more details, please download the PDF or feel free to contact us.
