The case study of furnace use and energy conservation in iron and steel industry

This work was performed on-site energy audits of 118 firms in the Taiwanese iron and steel industry during 2000–2008. It was found that the total potential energy savings was estimated about 79,160.8 KL of crude oil equivalent (KLOE). It was identified to generate potential electricity savings of 170,322.8 MWH, fuel oil savings of 22,235.1 kL, steam coal savings of 4922 tons, and natural gas (NG) savings of 10,735 kilo cubic meters. It was represented a total reduction of 217,866.5 tons in carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 5836 ha plantation forest. This study has established a national database presenting information and energy saving methods for energy users and has identified the potential areas for making energy savings to provide a energy conservation reference. It can assist the energy users in performing energy audits and increasing energy utilization efficiency.
