Cooling arrangement for shaft furnaces

A cooler for a shaft furnace comprises a metal plate for protecting the furnace walls from the heat effect arranged in the way of heat flow and a means for cooling said plate. The plate is made in the form of metal pipes filled with a coolant and sealed at the ends thereof. The coolant-filled ends of the pipes are rigidly fixed to the plate, and the coolant-free ends of said pipes are mounted within a cooling chamber with the coolant circulating therethrough. The cooling chamber is arranged exteriorly of the furnace wall. The coolant-free ends of the pipes are disposed slightly above those filled with the coolant. The plate is formed of two layers, namely, a high-heat-conducting layer and a low-heat-conducting one, the former facing the furnace working space and the latter being presented to the furnace wall. The interfacial plane of the layers is parallel to the longitudinal axis of the pipes. The present invention can be advantageously used for the protection of blast-furnace shells.

Cooler for a shaft furnace

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.

Blast furnace bottom cooling arrangement

An evaporative cooler for a blast furnace which is provided with a stave having a projection extending crosswise adjacent to the stave end face. The stave and the projection are provided with built-in pipes for a cooling agent to pass therethrough, with the pipe built into the projection being so arranged that its inlet and outlet end portions are interposed between the outlet end portions of the pipes incorporated in the stave. Such an arrangement of the pipes in the cooler provides for its extended service life.
