Description

METHOD FOR MOUNTING A BURNER FOR FEEDING OF REACTION GAS AND FINE SOLIDS INTO IN A REACTION SHAFT SPACE OF A REACTION SHAFT OF A SUSPENSION SMELTING FURNACE AND SUSPENSION SMELTING FURNACE
Field of the invention
The invention relates to a method for mounting a burner, such as a concentrate burner or a matte burner, for feeding of reaction gas and fine solids into in a reaction shaft space of a reaction shaft of a suspension smelting furnace as defined in the preamble of independent claim 1.
The invention also relates to a suspension smelting furnace as defined in the preamble of independent claim 9.
The straightness of a burner, such as a concentrate burner or a matte burner, for feeding of reaction gas and fine solids into in a reaction shaft space of a reaction shaft of a suspension smelting furnace is important in order to achieve even distribution of the feed of reaction gas and fine solids in the reaction shaft and in order to achieve a well-directed flame at the vertical center line of the reaction shaft space.
Traditionally the burner has been mounted at the top of the reaction shaft of the suspension smelting furnace so that the burner has been supported by the reaction shaft structure of the reaction shaft. A problem with such supporting is that because of thermal expansion of the reaction shaft structure of the reaction shaft, the straightness of the burner shifts as a result of thermal expansion of the reaction shaft structure of the reaction shaft.
Objective of the invention
The object of the invention is to provide a method for mounting a burner, such as a concentrate burner or a matte burner, for feeding of reaction gas and fine solids into in a reaction shaft space of a reaction shaft of a suspension smelting furnace and a suspension smelting furnace, where the thermal expansion of the reaction shaft structure of the reaction shaft has no or at least less effect on the straightness of the burner than in a traditional suspension smelting furnace.
Short description of the invention
The method for mounting a burner, such as a concentrate burner or a matte burner, for feeding of reaction gas and fine solids into a reaction shaft space of a reaction shaft of a suspension smelting furnace of the invention is characterized by the definitions of independent claim 1.
Preferred embodiments of the method are defined in the dependent claims 2 to 8.
The suspension smelting furnace of the invention is correspondingly characterized by the definitions of independent claim 9.
Preferred embodiments of the suspension smelting furnace are defined in the dependent claims 10 to 16.
The invention is based on supporting the burner of the suspension smelting furnace at the reaction shaft supporting metal structure for supporting a reaction shaft of a suspension smelting furnace. The reaction shaft supporting metal structure may be a part of a suspension smelting furnace supporting metal frame structure for supporting a reaction shaft structure of the reaction shaft of the suspension smelting furnace, for supporting an uptake shaft structure of an uptake shaft of the suspension smelting furnace, and for supporting a lower furnace structure of a lower furnace of the suspension smelting furnace. By supporting the burner in this manner, thermal expansion of the shaft structure of the reaction shaft will not have effect on the straightness of the burner. By supporting the burner in this manner, centralizing of the burner with respect to the reaction shaft space of the reaction shaft is additionally easier.
