2. Resistor/load heat exchange

In most industrial electric furnaces, the heat flow is the result of heat exchanges by conduction, radiation and convection, which need to be evaluated as accurately as possible. The main rules governing these heat transfer modes are described in the following paragraphs. For further details, please refer to [BE 8 200] Transmission of thermal energy – Conduction, [A 1 540] Convective heat transfer, [BE 1 544] Convective heat transfer – Appendix...
