Abstract:
The condition assessment of condensers in thermal power plants presents significant challenges, primarily due to the lack of comprehensive data, particularly in the context of non-destructive testing (NDT), which is often not collected consistently or systematically. This paper addresses these challenges by thoroughly reviewing available non-destructive test reports and microstructure analysis data to evaluate the health of the condenser in a 300MW thermal power plant. Key operational and performance parameters, such as back pressure, terminal temperature difference (TTD), temperature rise (TR), and chlorine content of colling water, have been analyzed to assess the condition of the condenser. Additionally, a degradation growth model is developed to predict tube failure, and a retubing strategy is proposed to mitigate the risk of failure and optimize performance.
