PROBLEM TO BE SOLVED: To provide a method for controlling inner pressure of a cooling chamber of a coke dry-cooling apparatus capable of preventing leakage of the inside gas of a cooling tower into the peripheral environment and air-inflow into the cooling tower. SOLUTION: This method for controlling inner pressure of a cooling chamber of a coke dry-cooling apparatus is characterized in that the opening X of a damper for controlling the inner pressure of the cooling chamber of the objective cooling tower regarding pressure control is set based on the following equation and controlled in advanced before red-heated coke is charged into another cooling tower. X=[1+k(PMAX-Pa)].X0 Here, X0: the opening of the damper for controlling the inner pressure of the objective cooling tower regarding pressure control during the previous charging of red-heated coke into the above- mentioned other cooling tower; PMAX: the maximum inner pressure of the cooling chamber of the objective cooling tower regarding pressure control during the previous charging of red-heated coke into the other cooling tower; Pa: the set value of the inner pressure of the cooling chamber of the objective cooling tower regarding pressure control; k: a fixed number.
