Abstract

PURPOSE:To prevent the load on a generator from becoming astable by a method wherein a plurality of inlets for receiving cooling water are provided in a direct contact type condenser and the vacuum degree of the condenser is controlled by controlling collectively or individually the flow rates of the cooling water at the inlet ports. CONSTITUTION:Adjust valves 3 and 13 for controlling the flow rates of the cooling water are provided in a pipe 5 leading to the condenser 4 such that the valve 3 opens wider gradually in response to the output signal of an adjust more 2 when the vacuum degree within the condenser 4 lowers while the valve 13 opens after the flow rates of the cooling water reach the values around the turning points of curves 6 and 7 of the attached graph. With the above structure, the cooling water is introduced into the second stage tray 11 only when the valve 13 opens immediately after the valve 3 opens to a predetermined degree so that the cooling water in the second stage tray 11 is mized with the cooling water fqlling from the first stage tray 10 to thereby lower the temperature of itself and as a result, the condensing capacity of the cooling water in the second stage tray 11 and downward is increased. Accordingly, the vacuum degree of the condenser increases or decreases in response to the increase or the decrease of the quantity of the cooling water and a wide range of control over the vacuum degree can be performed.
