ABSTRACT:
A method of preventing occurrence of pulsation in a circulating liquid for evaporative cooling which, in the case of passing the circulating liquid received within a steam separator through a cooling stave of a blast furnace and feeding said circulating liquid back into the separator through an inlet thereof thereby to perform the evaporative cooling operation for said blast furnace, comprises the step of raising, where the fraction dryness of the circulating liquid fed back into the separator is not greater than a prescribed value, the surface level of the circulating liquid within the separator up to a position higher than said inlet, and the step of lowering, where said fraction dryness of said circulating liquid exceeds said prescribed value, said surface level up to a position lower than said inlet.
