LeanCarb™ · Decarbonization suite

The LeanCarb™ product line targets CO₂ reduction at existing blast furnaces — retrofitting hardware, not replacing the route.

01

Hot blast booster

Delivered with LuxPlasma

Air-plasma torch between cowpers and bustle pipe. Recovers lost hot-blast temperature on aging stoves, substitutes prohibitive natural gas or coke-oven gas with renewable electricity.

  • Recovering the nominal hot blast temperature of aging hot stoves
  • Increasing the hot blast temperature and saving coke (1 kg coke per 10 °C)
  • Substituting prohibitive natural gas or coke oven gas at hot stoves by renewable electricity

Injection

Plasma + H₂-rich fuel at tuyeres

Smart combination of plasma power and hydrogen-rich auxiliary fuel injected at the tuyeres. Reversible retrofit that pushes the H₂-injection limits set by the BF heat balance.

  • Up to 20% CO₂ reduction
  • Low CO₂ abatement cost
  • Reversible, no major changes at the BF
  • Flexibility to use cheap renewable electricity when available

Decarbonization · LuxPlasma

Century 21st will be electric.

For centuries the blast furnace has been the undisputed champion of ironmaking. Its electrification is an evidence to go along with CO₂ emission reduction.

Europlasma and Phoenix Technologies SA join their respective know-how and create a joint venture LuxPlasma.

LuxPlasma will supply the plasma torches producing the hot gas needed by the blast furnace and thus substitute fossil fuel by decarbonized electricity.
