I finally saw the new cupola upgrade at the local foundry.

Its heat recovery system is a game changer.

At the Riverside foundry, I heard the heat recovery only cuts about 10% of energy use, @murray.troy. I mean, that's okay, but it's not the huge change people are talking about. Maybe it's just me, but I've seen older systems that did almost as well.

How much energy does it save?

Actually got closer to 20% at our place after some fine tuning. The older gear just can't hit those numbers. Key was matching the recovery rate to our actual melt shop schedule.
