Control method of suspended solids in floating melting furnace, floating melting furnace and concentrate burner

摘要

The present invention relates to a method for controlling suspended matter (8) in a floating melting furnace (1), a floating melting furnace and a concentrate burner (2). In this method, in addition to the finely divided solid (6) and the reaction gas (7), the reducing agent (13) is supplied into the floating melting furnace (1), and the reducing agent (13) is the reducing agent (13). It is supplied to the surface (9) of the lysate (10) through the suspended matter (8) of the reaction shaft (2) in the form of a concentrated flow, and the reduction zone (15) containing the reducing agent (13) is passed through the lysate (15). It is formed within the collection zone (14) of 10). [Selection] Figure 5
