A solução de aquecimento certa para processos de secagem na fabricação de cátodos

Daniel Burton, Business Development Manager, KanthalGas burners have long been the traditional choice of heating solution for ladle preheating. This is despite their poor thermal efficiency since most of the heat generated is lost through exhaust gasses rather than used to heat the actual ladle. Not only does this increase energy costs, but also results in high emissions.

“With gas burners, you’re releasing all these poisonous gasses into the factory and into the atmospheres, such as carbon dioxide, monoxide and nitrous oxides,” says Daniel Burton, Business Development Manager, Kanthal. “This is not only harmful for the environment but also creates a potentially hazardous working environment inside the factory.”

A cleaner, more efficient alternative

By replacing gas burners with electric heating, such as Kanthal’s Tubothal® and Kanthal® Flow Heater, aluminum producers can benefit from a huge improvement in thermal efficiency.

By replacing gas burners with electric heating, such as Kanthal’s Tubothal® and Kanthal® Flow Heater, aluminum producers can benefit from a huge improvement in thermal efficiency – from around 40 per cent up to over 95 per cent. This translates into an energy saving of around 60 per cent. Furthermore, all exhaust gasses and emissions are reduced to virtually zero.

“There are a whole host of environmental benefits to electric heating, namely the elimination of carbon dioxide emissions. But it also makes the factory a much safer, cleaner and quieter work environment,” adds Daniel. “You’re removing all the harmful gasses as well as reducing the noise levels significantly. On top of that, you can also free up a lot of space on the factory floor as you no longer need to reroute gas pipes and so on.”
