ABSTRACT:
The arrangement for cooling the bottom of a blast furnace comprises cooling plates mounted between the furnace lining and shell and forming vertical and horizontal rows. Each cooling plate incorporates coil pipes situated in two planes parallel to the furnace shell, the coil pipes being connected to each other in vertical rows. There are at least two coil pipes in one of the vertical planes in each plate. Such coil pipes in the plates mounted in the uppermost horizontal row are connected to coil pipes mounted in the top portion of the furnace in two different vertical planes. At least one coil pipe is situated in the other vertical plane in each cooling plate. The coil pipes in the plates mounted in the lowermost horizontal row are controllably connected to cooling medium feed collectors of the furnace common cooling system and to a high-pressure cooling medium source. Same coil pipes incorporated in the plates mounted in the uppermost horizontal row are controllably connected to the cooling medium return collector of the furnace common cooling system and to a high-pressure cooling medium receiver.
