Abstract

The invention relates to a method and an industrial plant for separating a waste material (1) comprising at least one metal (2) and at least one organic material (3). A separation fraction (4) of the waste material (1) is provided, said separation fraction being separated from the waste material (1) during mechanical preparation. The separation fraction (4) comprises briquets (5) made from the waste material (1) and optionally a coarse fraction (6) of the waste material (1) or of a further waste material (7). The separation fraction (4) has a calorific value of 5 MJ/kg to 30 MJ/kg and a maximum copper content of 0.1 wt% to 20 wt%. A reactor (8) is charged continuously or batchwise with the separation fraction (4), and the separation fraction (4) is combusted. In addition, the separation fraction (4) is melted into at least one liquid slag phase (10) and into a liquid metal-containing phase (11). At least one portion (12) of an incompletely combusted flue gas (13) is conducted out of the reactor (8) and into a thermal post-combustion plant (14), where a portion (12) is post-combusted.

Abstract

The invention relates to a process for producing briquettes (1), to a briquette (1) made of a waste material (2) and to the use of a briquette (1) in the process according to the invention. The process provides for providing a waste material (2) comprising at least one metal (3) and at least one organic material (4). It comprises performing a single- or multistage mechanical workup of the waste material (2) and a separation of at least one first fraction (5) from the waste material (2). A briquette mixture (6) containing the at least one first fraction (5) is produced, wherein the at least one first fraction (5) has a heating value of 0 MJ/kg to 30 MJ/kg. A heating value of the briquette mixture (6) is adjusted by varying at least the first fraction (5). The briquette mixture (6) is introduced into a briquetting apparatus (7) and pressed into briquettes (1) therein. This affords briquettes (1) having a heating value of 5 MJ/kg to 30 MJ/kg and having a maximum copper proportion of 0.1% by weight to 20% by weight.

Abstract

The present invention relates to a method for pneumatically blowing a powdery substitute reducing agent into a gasification reactor in a dense flow method by means of a transport gas or via a tuyere into a blast furnace such that the substitute reducing agent is gasified in a gasification reaction. The transport gas comprises a fuel gas the constituents of which or the oxidation constituents of which are at least partly involved in the gasification reaction.
