Induration Furnace fun factsThe typical furnace has anywhere between 25-40 fuel burners. Each burner is pumping out a whooping 15,000,000 btu/hr. Divide that by 140,000 btu and u get 107 gallons per hr. Times that by 4 and you get , let's say 400L to be nice. So that's 400L per burner per hr. Now times say 20 burners(small furnace). Ok so 8000L per hr for the induration furnace. But wait. It runs 24 hrs a day. Oh my. 8000x24=192000L per day. Those dual tanker trucks you see at your favourite gas station are 50000L trucks. So thats a grand total of 4 dual tanker trucks per day in one small induration furnace. Wowzers. Now 192000L x $1.50 = $288,000 per day. It shouldn't be a surprise that these companies want to switch out heat sources. They have a dirty little secret. Once the masses find out they be begging for plasma torches.
