【発明の名称】過熱された還元ガスの高炉への噴射方法
Document Type and Number:
Japanese Patent JPS58500412
Kind Code:
A
Abstract:
Overheated reducing gases are injected into the blast-furnace, at the main blast-pipes, at a temperature ranging from 1500 to 2800`C, produced from solid fuel, said gases containing essentially CO, Hu, Nu, COu and HuO. These reducing gases are obtained from a solid fuel, preferably dried and finely ground, injected in adequate proportions (O/carbon ratio) in a reactor where it is gasified by contact with an oxidizing agent such as air, over oxygenated wind or recycled top gases having a sufficient COu content. These reducing gases are preferably overheated by electric process, particularly in a plasma torch.
