Just found out our old cupola furnace from the 70s used 40% more coke than a modern one
I was going through some old plant records in the office, looking for a shipping date, and I found a stack of fuel logs from 1978. I started comparing the coke usage per ton of iron from back then to our numbers now. The old cupola we replaced five years ago was burning through almost 2,000 pounds of coke for a 5-ton melt. Our current induction setup uses the power equivalent of about 1,200 pounds for the same job. I knew it was less efficient, but seeing the actual numbers written down in that old ledger really hit me. Some guy was shoveling all that extra coke every single day for years. Makes you think about all the heat and money just going up the stack. Has anyone else dug up old records that showed how much the tech has really changed?

Wow, that's a crazy difference to see on paper. I mean, you always know it was worse, but the actual numbers make it so real. All that wasted effort just hits different.

Numbers don't tell the whole story though.
