| Abstract | As many Combined Cycle Power Plants have come into operation over the last 10 years, premature condenser tube failures have been experienced at several installations. This paper reviews factors and mechanisms contributing to such failures. The steam turbine condenser must operate under a demanding, wide range of conditions. Tubes within the condenser experience cyclic stresses, direct contact from admission of high-energy steam into the condenser, and the effects from a wide service range beginning with start-up and commissioning through continuous or intermittent daily operation. A number of factors go into properly designing condenser related sub-systems as required by the functional operation of the combined cycle plant. The condenser bypass system is a critical component directly affecting the operation, maintenance and control of conditions experienced by the condenser. Part 1 of this paper identifies related problems experienced, in the field, within the condenser considering operation and maintenance, and also provides design considerations to avoid occurrence of tube failures. Part 2 of this paper addresses many key points for consideration with respect to the design and implementation of the high-energy bypass system leading into the condenser. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
