Abstract
For one method of a cost reduction, we focused on the electricity cost, which had a high ratio in our total cost,. We have introduced ‘Co-generation System by ESCO’ , which aimed to utilized the unused waste heat of generator for the support of dryer in our plants effectively.
By the introduction of this system, our electricity cost in 2004 reduced approximately 17.4% and our fuel cost by approximately 1.6% in our plants by the way of waste heat recovery.
Also, we have reduced the fuel cost by 100% in our plants' dryer since August, 2005.
The introduction of “Co-generation System” has brought benefits for us.
