Abstract
A condenser that restrains fluctuations in the condenser vacuum in a power generating installation. In particular, the condenser has a circulating path through which cooling water flows; a tube nest for condensing steam from a steam turbine with the cooling water; and a discharge path. Additionally, a bypass tube; a control valve for controlling the flow rate of the cooling water supplied from the circulating path to the discharge path; a recirculating path; and a booster pump that controls the flow rate of the cooling water are provided. One of the temperature, the flow rate and both the temperature and the flow rate of the cooling water to flow through the two tube nests is deviated from the temperature and the flow rate of the cooling water on the upstream side of the circulating path using the control valve and booster pump.
