Condensate purification such as demineralization, filtration or sterilization for use in a power plant of the type having at least one main condenser with a hot well as part of the steam cycle and in which the condenser is connected to receive steam from a turbine generator and the hot well is connected to discharge to a main condensate pump. Purification of the condensate is executed with improved method and apparatus comprising a side stream demineralization system. The improvement includes a baffle mounted within said main condenser defining an upstream portion of the condenser on one side of the baffle and a downstream portion of the condenser on the other side of said baffle. The condenser hot well is located on the downstream side of the baffle. A passageway is defined over the baffle for flowing fluid therethrough to the hot well. The passageway includes a weir cooperatively disposed therewith on the upstream side of the baffle to hold back a pool of fluid from flowing through the passageway. Apparatus for water purification comprising demineralizers is spaced apart from the condenser. A first pipe connects said pool of fluid with the purification apparatus. A pump is connected with the first pipe for causing fluid flow through the purification apparatus. A second pipe is provided for connecting the water purification apparatus with said pool for recirculating water back to the pool for further purification. A third pipe connects said purification apparatus with the downstream side of the baffle so that the condensate water can reach said hot well. Optionally the condensate can be reheated while flowing towards the hot well.
In a power plant steam cycle having at least one main steam condenser with a hot well, a side stream condensate purification system for clean-up of the feed water comprising:
Improved apparatus for purification of the condensate used in a power plant, said power plant of the type having a main condenser with a hot well as part of a steam cycle and in which said condenser is connected to receive steam from a turbine generator and said hot well is connected to discharge to a main condensate pump, said improved apparatus comprising:
A method for removing impurities from water in a steam generated power plant having a working fluid path including a condenser with a hot well and in which the fluid passes through the condenser to the hot well, said method including the steps of interrupting at least a part of the fluid flow through said condenser upstream of the hot well, withdrawing interrupted fluid from said condenser, separating impurities from said removed fluid at a location spaced apart from said condenser, and then returning said fluid to at least one of (a) the hot well of said condenser, (b) the upstream part of said condenser from which it was withdrawn thereby recirculating the fluid.
