PURPOSE:To improve the deaeration effect by a method wherein condensed water collected in a hot well is flowed uniformly, and the agitation by steam as well as boiling and evaporation on the outside of heating pipes arranged in a condenser is acceralated. CONSTITUTION:Partition plates 11, a covering plate 12 are compared at the inside of the hot well 3 situated at the lower part of the condenser 1, and heating pipes 10 are provided in the passage which is divided with partition plates 11 at the lower part of the fluid surface of the stagnant and at the opposed position of an outlet 4 of the condensed water. The heating pipes 10 are connected to a heating medium system 23, and the introduction of heating medium is carried out at will by an ON-OFF valve 33. Heating medium is composed of coarse steam, heated water or high temperature gas etc. and is used appropriately. When the plant is started, the condensed water in the hot well 3 is taken out by a condenser pump 5, and is introduced to a condensed water re-circulate system 22 from a condensed water system 21, and is supplied to spray system 22, and is supplied to sprayers 6, 7 and is dispersed in the condenser 1. When the plant is started, the vacuum rate is increased in the condenser, and soluted oxygen is released from the interface of sprayed fluid. Subsequently, the condensed water which flows down on the upper surface of the covering plate 12 is boiled and evaporated due to the heat from the heating pipes 10, and the fluid at the outside surface of the heating pipes 10 is agitated by the bubbles thereof. |
