Abstract | Summary form only given. The twin torch plasma arc can generate a wide space of high temperature and treat non-conducting material, and also a mixture because it is a non-transfer type. Therefore, the twin torch plasma arc is a more effective device for treatment of hazardous waste. In this paper, a 300 kW twin torch plasma arc furnace was developed. This facility was designed to enable to be mounted on commercial trucks. A set of two DC power supplies is used to generate the arc. The arc is generated between a tungsten tip cathode with a nozzle and a hollow carbon anode. The electrode angle is 60 degree, and it is adjustable. The crucible in an inner diameter of 1 m can rotate in order to treat the waste easily. The crucible and a chamber (length=2 m, width=1.5 m, height=1.5 m) have firebrick in order to keep the high temperature. The off gas can be treated by bag filter and scrubber. The gas is analyzed by using a GC-MS. The arc temperature is measured by spectroscopy. As a result, the arc temperature is 11,000 K. The SS and SUS were melted at 200 A, 200 V. The injection needle and diaper were treated at 200 A, 100 V in success. The off gas does not violate relevant law |

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.
