Problems solved by technology

However, when the coal used has a high caking property, the molded carbon is softened and melted in the shaft furnace, which makes it difficult to operate the shaft furnace and causes deterioration of coke quality such as deformation or cracking.

Embodiment

[0067] In order to confirm the effect of the present invention, use Figure 4 In the ferrocoke manufacturing test apparatus shown, the ferrocoke manufacturing test was carried out in the case where the high-temperature gas blowing tuyeres were in two stages and in the case of one stage. Figure 4 neutralize figure 1 The same parts are marked with the same symbols. for Figure 4 The vertical shaft furnace 1 shown has a total length of 13.0m. The horizontal line from the upper end of the furnace to the feed line is set at 0.65m, and the horizontal line from the feed line to the center of the low-temperature gas blowing tuyere 9 is set at 3.5m. , Set the center of the low-temperature gas blowing tuyere 9 to the center of the upper high-temperature gas blowing tuyere 11 at 3.0m, set the center from the high-temperature gas blowing tuyere 11 to the center of the lower high-temperature gas blowing tuyere 13 2.0m, the center of the lower high-temperature gas injection tuyere 13 t...

Abstract

The object of the present invention is to provide a vertical shaft furnace, which can simplify the equipment and not complicate the operating conditions; A vertical shaft furnace for continuously producing target products through combustion, gasification, dry distillation, or reduction. It is characterized in that two high-temperature soaking zones are installed in the length direction of the furnace in order to form a high-temperature soaking zone of a predetermined length below the center position in the length direction of the furnace. Gas is blown into the tuyeres 11 and 13.

Description

technical field [0001] The present invention relates to a vertical shaft furnace, an iron coke manufacturing facility equipped with the vertical shaft furnace for producing iron coke, and a method for manufacturing iron coke using the same. Combustion, gasification, dry distillation or reduction of the charge to continuously manufacture the target product. Background technique [0002] In the blast furnace operation, metallurgical coke produced by dry distillation of coal in a coke oven is generally used. Coke for metallurgy has functions as a spacer for improving ventilation in the blast furnace, a function as a reducing material, a function as a heat source, and the like. [0003] In recent years, from the viewpoint of improving the reactivity of coke, a technique of mixing iron ore with coal to obtain iron coke for metallurgy has been known. As a technology for producing iron coke by dry distillation of iron source materials such as coal and iron ore using a common cham...
