APPARATUS FOR BLOWING DUST COAL OF MELTING FURNACE, AND BLOWING METHOD THEREFOR

摘要

In order to blow dust coal at an upper part of a bed of a melting furnace so as to enhance ore reducibility while improving the oxidation degree of a reducing gas to be generated at the melting furnace, thereby enabling a portion of carbon dioxide inside the melting furnace to be lowered and, simultaneously, a portion of carbon monoxide to be increased, provided are: an apparatus for blowing the dust coal of the melting furnace, comprising at least one or more dust coal blowing burners, which are provided at the upper part of the bed of the melting furnace, and a control unit provided so as to control the blowing amount of dust coal to be supplied to the dust coal blowing burner; and a dust coal blowing method comprising: a step of blowing the dust coal by using the dust coal blowing burner provided in the melting furnace; and a control step of controlling the melting furnace blowing environment of the dust coal.
