| Abstract | Flexibility is key to the future success of natural gas fired power generation. As renewable energy sources continue their penetration of the global energy market, the need for reliable, flexible generation will increase. Gas turbines equipped with a fuel flexible combustion system allowing the capability to extend in-emissions-compliance turndown limit, will have a significant advantage supporting todays and future energy market demand. The FlameSheet™ combustor incorporates a novel dual zone burn system to address operational and fuel flexibility with low emissions and extended turndown. FlameSheet™ is simply retrofittable into existing installed E/F-class heavy duty gas turbines and is designed to meet the energy market drivers set forth above. The operating principle of the new combustor is briefly described, and details of implementation and extended validation results on two General Electric 7FA heavy duty gas turbines operating in a combined cycle power plant since 2015 with over 36,600hrs of uninterrupted commercial operation is discussed, with special focus on operational profile optimization to accommodate the heat recovery steam generator (HRSG), while substantially increasing the gas turbine normal operating load range. Emphasis is also provided on performance assessment, combustion and downstream hot gas path component inspection and durability assessment after 16,600 hours of operation in a 7FA gas turbine. |

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.
