| Abstract | Pilot-scale pulsed corona discharge process was applied to the removal of SO/sub 2/ and NO/sub x/ from iron-ore sintering due gas. We made use of a two-stage magnetic pulse compression modulator to produce repetitive high voltage pulses. The dependencies of variables such as channel width, voltage level and dust content on power delivery were examined. In this system, we were able to deliver pulse power with peak voltage of 140 kV and peak current of 3.3 kA to the corona reactor. Under spark-over voltage, the energy delivered per pulse was almost similar regardless of the channel width. The energy conversion efficiency of the magnetic pulse compression modulator was not largely affected by the voltage level and the channel width, and around 65%. The dust content in the flue gas up to 4.6 g/Nm/sup 3/ did not have any influence on the power delivery. The maximum energy intensity that can be obtained was 0.5 J/pulse/m and 0.44 J/pulse/m when the channel width was 300 mm and 200 mm, respectively. More than 90% and 80% of SO/sub 2/ and NO/sub x/ could be removed in the corona reactor in the presence of additives such as ammonia (NH/sub 3/) and propylene (C/sub 3/H/sub 6/). |

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.
