How does a condensate polishing unit work?
Condensate polishing typically involves ion exchange technology for the removal of trace dissolved minerals and suspended matter. During the process of steam generation in power plants, the steam cools and condensate forms. The condensate is collected and then used as boiler feed water.
What is the purpose of condensate polishing unit?
Condensate polishers are used to maintain a proper quality of water by removing impurities from return condensate. The decision to polish return condensate for re-use is purely economical. The condensate can be returned to an ultra pure state by simple polishing rather than using fresh make up process water.
What does a water polisher do?
The Water Polisher is an advanced stormwater treatment system utilizing an up flow media filter with built-in pretreatment. This patented design provides double-chambered separation to remove large to fine sediments and prevent clogging challenges found in downward flow media filters.
What is a polishing unit?
Fuel polishing units remove water and particulates from diesel fuel which is stored for the medium to long term. Over time, stored fuel for back up generators or on boats degrade and become infected with water from condensation.
What is condensate in a power plant?
The condensate system includes anywhere that the steam condenses to form liquid water. As the vapor leaves the low-pressure turbine it contains droplets of water. It is passed outside of homogenated tubes in the condenser through which certain water is passed.
What is suspect condensate?
In case the process side operating pressure is lower than the steam side one, the possibility of condensate contamination with the process fluid is minimal and the condensate produced from such a source can be deemed ‘clean condensate’; on the contrary, in case the process side operating pressure is higher than the one …
What is CPU in water treatment?
Condensate polishing typically involves Ion Exchange technology for the removal of trace dissolved minerals and suspended matter. During the process of steam generation in power plants, the steam cools and condensate forms. The condensate is collected and then used as boiler feed water.
How can I naturally clear my fish tank water?
Keeping the aquarium very clean by removing debris such as decaying plants and uneaten food, vacuuming the gravel regularly, and performing partial water changes will quickly resolve most cases of bacterial bloom. Cut back feeding to every second or third day, which will reduce excess food decay.
What is condensate polishing plant?
A condensate polisher is a device used to filter water condensed from steam as part of the steam cycle, for example in a conventional or nuclear power plant (powdered resin or deep bed system).
What is condensate water?
When water vapor in the air (often described as humidity) comes into contact with a colder surface, the water changes from a gas to a liquid and collects onto the cold surface. This water vapor in the air that becomes liquid is referred to as condensate.
What is hotwell power plant?
The condenser hotwell serves as a water reservoir for the turbine cycle. When hotwell level reaches the low point, a valve opens to supply make-up water to the cycle. When hotwell level reaches the high end of the level range, a dump valve opens to move the condensate from the hotwell to a condensate storage tank.
What is the condensate polishing unit used for?
Which is the best industrial softener for condensate polishing?
NECO industrial water softener condensate polisher systems are the perfect solution for cleaning boiler condensate return water. These stainless steel industrial softeners for condensate polishing are often used in power generation, co-generation plants and several heavy industries with large boiler systems.
What’s the difference between ion exchange and condensate polishing?
Condensate polishing is a proven method of producing high purity demineralized water from recovered boiler condensate. Condensate polishing differs from regular ion exchange in that ion exchange is only part of the overall process as the condensate is already of high quality and only requires polishing.
What causes corrosion in a condensate polisher?
Both dissolved (i.e. silica oxides) and suspended matter (ex. iron oxide particulates from corrosion, also called ‘crud’), as well as other contaminants which can cause corrosion and maintenance issues are effectively removed by condensate polishing treatment. ^ a b Perrow, Charles (1999).
