Problems solved by technology

Electrical heating however has the disadvantage that the efficiency is particularly low, so that the initial energy requirement is relatively high and the method is therefore also less economical

Embodiment Construction

[0021] figure 1 A sectional view shows a burner arrangement 1 , in particular for heating or keeping a radiation protection device for castings and / or a submerged casting device, in particular a continuous casting plant. In this case, the burner arrangement 1 is provided with a burner 3 arranged around the submerged nozzle 2, which according to the invention forms a microporous burner. The microporous burner has the advantageous property that, as a gas burner, it permits the combustion of a gas-air mixture in a porous structure or structure which does not form an open flame to some extent or at all. As a result, a flameless volumetric combustion of a gas-air mixture is achieved. In this way, a combustion in the porous structure takes place, so that after the introduction of the gas-air mixture, an exhaust gas flow is produced on the outlet side as a reaction product.

[0022] exist figure 1 The microporous burner 3 represented in is composed of multiple sections. The indiv...

Abstract

The invention relates to a burner arrangement (1) in particular for heating or keeping warm, in particular casting stream protection devices and / or immersion casting devices of a continuous casting plant, comprising a reservoir (5) that can receive, in particular a shroud tube or an immersion tube, said reservoir comprising a base (6) and a cover (7). The wall (8) of the reservoir (5) is formed byat least one porous burner.

Description

technical field [0001] The invention relates to a burner arrangement, in particular for heating or keeping warm a continuous casting plant, in particular a casting radiation protection device and / or an immersion casting device. Background technique [0002] During melting operation, for example in a steelworks with a continuous casting plant, molten metal is usually conveyed by means of a ladle to the pouring point of the continuous casting plant. At the same time, the molten metal flows from the ladle into a distributor via a casting radiation protection device, for example a submerged tube. From the distributor, the metal flows into the mold of the continuous ingot casting plant through a submerged nozzle, for example a submerged tube. The submerged sprue and possibly the submerged tube are preheated before casting starts and are not normally used in casting runs. In this case, a burner is operated with a fossil fuel, such as natural gas, and an oxygen carrier, such as a...
