Doosan Heavy Industries & Construction has awarded Siemens Water Technologies with a contract to provide a condensate polisher package with external regeneration facility to GMR Chhattisgarh Energy Private Limited.

The polishers will be used at the 1,370 MW Raipur Super Thermal Power Plant in the state of Chhattisgarh, India,.

Siemens will design, engineer and fabricate the condensate polisher system, which is currently scheduled for start up in June 2014.

For the Raipur power plant, Siemens Water Technologies will provide six condensate polishers that will treat over 3,100 m3/hr of return condensate. Condensate is formed when the steam from the boiler cools. To reuse it, impurities such as metal oxides, trace ionic impurities and silica have to be removed by condensate polishers. They help to improve and maintain the boiler feed water chemistry.
