The condensate and feed water chemistry is critical to the overall corrosion and reliability of the thermal power generating units. The effect of dissolved oxygen on corrosion of WB 36 material and carbon steels in feed and condensate water system. The presence of high levels of dissolved oxygen within condensate can quickly contribute to; accelerated corrosion, the need for additional treatment requirements, increased maintenance, operational challenges and even early equipment failure. The condenser water cycle, dissolved oxygen started increasing at Unit 2 of the VIPL, Butibori. An evaluation of the high condensate dissolved oxygen levels that were being experienced at Unit 2 indicated of the Condensate extraction pump system include mechanical seal vent line, connector, valve gland, dummy plug etc. A new approach to dissolved oxygen control was necessary in the condensate and feed water cycle could be controlled satisfactorily. This paper describes the various corrective actions undertaken as well as proposed for future implementations are discussed and recommendations are provided for proper operation and maintenance.
