Abstract
A method for heating a furnace (40) used for metal processing by combusting a fuel in the furnace (40) by supplying an oxidizing gas through an oxidizing gas supply line (20) into the furnace (40) and by supplying a fuel through a fuel supply line (30) into the furnace (40), wherein the oxidizing gas is supplied in form of a central oxidizing gas flow (24) together with a first shroud gas flow (25), and/or the fuel is supplied in form of a central fuel flow (34) together with a second shroud gas flow (35), and to a corresponding burner (10).
Claims13
A method for heating a furnace (40) used for metal processing, comprising:
- supplying an oxidizing gas through an oxidizing gas supply line (20) into the furnace (40), the oxidizing gas supplied as a central oxidizing gas flow (24) together with a first shroud gas flow (25) for the central oxidizing gas flow (24),
- supplying a fuel through a fuel supply line (30) into the furnace (40), the fuel supplied as a central fuel flow (34) together with a second shroud gas flow (35) for the central fuel flow (34),
- initially sucking the first shroud gas flow (25) into itself, and subsequently sucking an atmosphere of the furnace (40) into itself for moving a point of recirculation of the atmosphere away from a refractory wall of the furnace, and
- reducing particles in the atmosphere of the furnace (40) where the first shroud gas flow (25) is occurring in the furnace atmosphere.
