ABSTRACT:
A blast furnace cooling arrangemenet comprises a cooling screen which is disposed in an annular space between a furnace shell and its lining, and which is formed by vertically arranged rows of plates provided with main and additional internal ducts having common inlets and common outlets. Mounted above the cooling screen are drum separators which communicate through supply pipelines and take-off pipelines with the common inlets and outlets of the main and additional ducts of the plates of each vertical row, the above elements forming closed circuits of natural circulation of a cooling medium. Connected at the common inlets and outlets of the additional ducts of the vertical rows of the plates are circuits of forced circulation of a cooling medium. Each of the circuitsof forced circulation comprises a container communicating 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 additional ducts in the vertical row of the plates. The common inlets and outlets of the additional ducts are provided with distributing valves intended to selectively connect the additional ducts to the circuits of natural and forced circulation of a cooling medium.
