摘要： The invention relates to a device for directly monitoring the charging process on the inside of a shaft furnace (2), in particular a blast furnace, while said furnace is in operation. Said device comprises a measuring lance (12) mounted above the charge column (4) in the shaft furnace (2) in such a way that during the charging process it is subjected to the charge (8) falling out of a charging device (6), and sensor means (14) which detect the position of the falling charge (8) in relation to the measuring lance (12).

摘要： The present invention proposes a method for feeding pulverised coal into a blast furnace, wherein the method comprises the following steps: providing a tuyere stock (14) for blowing hot blast air from a bustle pipe (12) into a furnace hearth of a blast furnace through a tuyere (15) in an opening in the furnace wall (16); providing a pulverised coal injection lance (18) for feeding pulverised coal into the tuyere (15), the pulverised coal injection lance (18) comprising an inner pipe (20) for conveying pulverised coal and an outer pipe (22), coaxially arranged around the inner pipe (20), for conveying combustive gas, the inner pipe (20) forming a separation wall for separating the pulverised coal from the combustive gas, the pulverised coal injection lance (18) having a lance tip (24) arranged in the tuyere (15); allowing the pulverised coal and the combustive gas to form a mixture of pulverised coal and combustive gas at the lance tip (24); burning the mixture of pulverised coal and combustive gas in the tuyere (15); monitoring whether or not a flame at the lance tip (24) is burning; and upon determination that the flame at the lance tip (24) is not burning, reigniting the flame by temporarily reducing the flow of combustive gas through the pulverised coal injection lance (18).
