Topic: 3Abstract:
In recent years, environmental issues such as global warming and the energy resource depletion have become serious matters. So the steelmaking industry is strongly required to develop new technologies for further energy conservation in view of energy security. A lot of energy used for industrial processes has been wasted as heat. Waste heat recovery can be one of the key technologies to meet the requirement. Thermoelectric generator (TEG) is one of the promising technologies expected to play an important role for steel plantfs waste heat recovery, particularly radiant heat from steel products which had not been used yet efficiently. A 10-kW class in plant grid-connected TEG system was constructed in the continuous casting line at East Japan Works (Keihin District) of JFE Steel Corporation. The performance and durability of the TEG system have been investigated under various operating conditions. This paper will describe results of the verification tests at the continuous casting line.
