METHOD AND ARRANGEMENT FOR REMOVING OUTGROWTH IN A SUSPENSION SMELTING FURNACE.

摘要

The invention relates to method and to an arrangement for removing outgrowth in a suspension smelting furnace. The suspension smelting furnace comprising a reaction shaft (1) having a reaction shaft structure (9). The reaction shaft (1) comprises at least one opening (5) for an outgrowth removal means (6). The arrangement comprises at least one outgrowth removal means (6) comprising an outgrowth removal means (6) having a movable piston (7). The movable piston (7) of said at least one outgrowth removal means (6) being arranged such that the movable piston (7) of said at least one outgrowth removal means (6) can move in the opening (5) in the reaction shaft (1) and into the reaction shaft (1) to push possible outgrowth in the reaction shaft (1) by means of the movable piston (7) of said at least one outgrowth removal means (6).
