BLAST FURNACE COOLING ARRANGEMENT Abstract of the Disclosure A blast furnace cooling arrangement comprises a cooling screen which is disposed in an annular space between a furnace shell and lining and formed by vertic- ally arranged rows of plates provided with main and ad- ditional internal ducts having common inlets and common outlets. Mounted above the cooling screen are drum sep- arators which communicate through supply pipelines and take-off pipelines with the common inlets and outlets of said main and additional ducts of the plates of each vertical row, the above elements forming closed circuits of natural circulation of a cooling medium. Closed at the common inlets and outlooks of the additional ducts of the vertical rows of the plates are circuits of forced circulation of a cooling medium. Each of the circuits of forced circulation comprises a container communicat- ing with the common outlet of the additional ducts, a heat exchanger connected with the container, and a pump communicating through its inlet with the heat exchanger and through its outlet, with the common inlet of the ad- ditional ducts in the vertical row of the plates. The common inlets and outlets of the additional ducts are provided with distributing valves intended to select- ively connect the additional ducts to the circuits of natural and forced circulation of a cooling medium.
