So I have had the pleasure to service and work on this one of a kind monstrosity, well make that 2 as they are right next to each other. This is a Bloom Regenerative Melt Furnace and to my knowledge, it is really the only one of its kind around. I have worked on many other tower furnaces that melt metal but not like this. The video is just of the stand by flame while making a pilot flame adjustment on the opposite burner. When the doors to this furnace close, an end switch is made to engage the main flame. The main flue exhaust damper is then opened wide to draw the main flame over the entire metal bath to a point you can see the flame licking up the flue vent😳. It was not something I could safely show back when this video was taken. This furnace maintains a bath of Molten metal. The metal is poured into a large “ladle” that is attached to a suspension car. The die cast plant is outfitted with a track that this “suspension car” can stop at each die cast machine and top up the molten metal for the creation of automotive parts. Unfortunately I cannot show much more beyond this as it can get the company I work for in some hot water. I do however, feel fortunate to be one of a literal handful of people that know how to safely operate and service this beast. Think an attic is hot? (Yes I know, they are very hot😳) but try working above a unit with an internal furnace temperature of 2100 degrees Fahrenheit in July, while using 4’ and 3’ pipe wrench to rebuild the gas train😅 The company I work for was able to put a strategy many years ago (before my time). The process was to recycle the internal heat of the furnace to maintain the bath temperature of 1425 degrees Fahrenheit. Without going into full detail, this was done with an extra high volume exhaust, multiple dampers and a few more PLC’s. This effectively would keep one burner operating for a timed duration before changing over to the second burner. Before, both burners would run constant where as now in the regeneration process, only one burner has to run. This process would effectively maintain the furnace temp and bath temp while saving roughly more then half a million dollars a year on the gas bill🤙 A bill I would never want to see in my mailbox😬😅 #hvac #hvacr #burners #industrialhvac #hvaclife #hvactechnician
