That is not in any way related to the theoretical efficiency of resistance heating and not really of any help here unless there is some working fluid which allows for the temperatures needed for industrial processes. It might be possible to recuperate process heat if a suitable working fluid can be found which evaporates at the temperature of the product leaving the process chamber and condenses at a temperature suitable for (pre-)heating the process chamber. I have not heard of such though. |
