METHOD FOR RECOGNIZING DISPERSION STATE OF MINERAL CONCENTRATE IN MINERAL CONCENTRATE BURNER OF FLASH SMELTING FURNACE, AND SYSTEM FOR RECOGNIZING DISPERSION STATE OF MINERAL CONCENTRATE IN MINERAL CONCENTRATE BURNER OF FLASH SMELTING FURNACE

摘要

To provide a method for recognizing a dispersion state of a mineral concentrate in a mineral concentrate burner of a flash smelting furnace and a system for recognizing a dispersion state of a mineral concentrate in a mineral concentrate burner of a flash smelting furnace, capable of controlling state of a powder discharged from an opening by adjusting a fluid state of the powder.SOLUTION: A mass flow rate distribution and a temperature distribution of mineral concentrate particles M in a mineral concentrate burner 10 when an input condition of the mineral concentrate particles M supplied to the mineral concentrate burner 10 and an input condition of a gas supplied to the mineral concentrate burner 10 of a flash smelting furnace for measuring a dispersion state of the mineral concentrate particles M are calculated by a numerical simulation in advance, temperature distribution of the gas in the mineral concentrate burner 10 is measured, and dispersion of the mineral concentrate particles M in the mineral concentrate burner 10 is evaluated based on a numerical simulation result of the mass flow rate distribution of the mineral concentrate particles M in the mineral concentrate burner 10 at an input condition with which a temperature distribution equal to the measured temperature distribution is formed.SELECTED DRAWING: Figure 1
