What role does a large tube play in an industrial furnace?
Here's an example:

http://www.thalesgroup.com/Portfolio...K112/?pid=6903

"The new ITK 112 triode, intended for high-power induction and
dielectric heating applications, delivers continuous RF power of 280 kW.
It is especially well suited to industrial applications such as the
manufacture of rolled welded tubes, heat treatment of metals, and
textile and wood drying."

I see - so it actually powers an RF heating element? Pretty slick!


I would think it's an induction thing. The circulating currents set up
in the metal do the heating. With wood, it may well be something like
microwaves, heating the water content.

I think that's what I was thinking, except you put it a bit more
elegantly :-)
