O&MDeaerator degradation: Managing remaining life and component replacement
Proper attention to dissolved oxygen levels in feedwater is fundamental for long-term equipment reliability, especially in a combined-cycle plant. When equipment approaches its design life, proper use of new analytic tools and technical expertise can identify impending corrosion and erosion problems and provide you with an estimate of remaining equipment life.

GasBugok II Power Plant, Dangjin County, South Korea
South Korea, one of the “Four Asian Tigers” known for their aggressive economies, is boosting its electrical capacity with the recent addition of the Bugok II Power Plant. Ranked as the top plant in South Korea because of its efficient, environmentally friendly operation, the 565-MW plant is powered by combined-cycle units that burn natural gas. Part of this project’s success derives from the fact that Bugok I and II were the first projects awarded to a foreign company by a South Korean independent power producer.
