摘要： The invention relates to a method and an arrangement for operating an industrial furnace (10) which is directly heated by means of at least one first burner (14). According to the invention, the burner is supplied with fuel and combustion air in a first heating phase of the furnace, and that the flammable mixture formed in this way in the burner is brought to a reaction, and that the combustion gases produced are directed into the furnace inner chamber to be heated. After reaching a predetermined operating temperature, at which the reaction partners can burn in a flameless manner, the supply of a first of the two reaction partners to the burner is reduced at least to such an extent that no reactive mixture is formed in the burner, wherein the first reaction partner, or part of the first reaction partner that is no longer supplied to the burner, is fed to the furnace via a feed device (15) spaced apart from the burner, and then reacts in the furnace inner chamber with the second reaction partner still supplied to the furnace by means of the burner. A flameless, nitrogen oxide-poor combustion is thus achieved in the relatively large volume of the furnace inner chamber and a resumption of the combustion in the clearly smaller volume of the burner combustion chamber is reliably prevented.
