Energy recovery in the high temperature furnace using a high-emittance fiber (HEF) unit

Nihon Kikai Gakkai ronbunshu, 2016
We have studied the energy recovery effect in high-temperature furnace using a high-emittance fiber (HEF) unit. Previous studies have shown that energy recovery effect occurs as placing the HEF unit perpendicular to the gas flow.
