In Kingdom of Thailand, the model project for high-performance industrial furnace in aluminum industry has entered a stage of demonstrated operation.
Prior to the demo, opening ceremony was held on October 28, 2009 at the site company, Varopakorn Public Co., Ltd. in Thailand.
The high-performance industrial furnaces, which have been introduced into Thailand for the first time, allow for combustion using highly preheated air (about 1,100℃) and thus are expected to promote energy saving and reduce NOx emissions.
We believe we will be able to contribute to significant energy savings and the reduction in greenhouse gas emissions through the promotion of broader use of the high-performance industrial furnace technology in Thai aluminum and steel industries.
