| Abstract | Research conducted at the supercritical (SC) facility of MIT’s Energy Laboratory provided visual confirmation of a single phase, homogeneous water/fuel mixture near the critical temperature and pressure of water. This mixture was subsequently burned under atmospheric spray conditions with very low NOx, smoke, CO, and HC. Larger supercritical fuel systems were developed and tested in a 300 hp combustion turbine combustor simulator, and a 30 kW microturbine. Early results comparing combustion of this water/fuel mixture with standard #2 fuel operation in the 30 kW turbine generator were uniformly positive. At full load conditions, levels of under 2.5 parts per million (ppmv) of NOx were achieved, over 90% lower than the baseline emissions, with CO emissions under 5 ppmv. These emission levels were in fact lower than those recorded at full load with a similar model microturbine, fueled with natural gas. These low levels were achieved without the increase in CO that is typically observed with water injection. It is suspected that these results are caused not only by thermal effects of the steam but by altering reactions in the flame. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
