Abstract

The present invention generally relates to apparatuses and methods for use in metal melting, refining and / or other processing, such as, for example, steel making in an electric arc furnace (EAF), and more particularly, to improved burner panels and related methods for the introduction of various energy sources, such as, for example, chemical energy and particulates.

Description

technical field [0001] Various embodiments of the invention generally relate to apparatus and methods for melting, refining and processing metals. More specifically, embodiments of the present invention generally relate to burner panels for use in metal furnaces and / or the like. Background technique [0002] The field of steelmaking has been very well developed. Typically, and most commonly, an electric arc furnace (EAF) is used to make steel by applying an electric arc to melt one or more scrap metals and / or other pig iron products and alloys placed within the furnace. Other methods include modified EAF to make steel by melting DRI (Direct Reduced Iron) combined with molten metal from a blast furnace. In order to improve the steelmaking process, additional chemical energy is supplied to the furnace through auxiliary devices. The most commonly used forms of auxiliary devices include burners, injectors, and nozzles, which use fuel and oxidizing gases to produce combustion ...
