Document Type and Number:
WIPO Patent Application WO/2013/079762
Kind Code:
A8
Abstract:
The invention relates to a method for controlling suspension (8) in a suspension smelting furnace (1), to a suspension smelting furnace, and to a concentrate burner (2). The method comprises feeding additionally to pulverous solid matter (6) and additionally to reaction gas (7) reducing agent (13) into the suspension smelting furnace (1), wherein reducing agent (13) is fed in the form of a concentrated stream of reducing agent (13) through the suspension (8) in the reaction shaft (2) onto the surface (9) of the melt (10) to form a reducing zone (15) containing reducing agent (13) within the collection zone (14) of the melt (10).
