Background
The present phase of the energy efficiency intervention program has been designed to implement and commission the technology researched and developed as part of the previous phase of the program. In the first phase, in order to tackle the collective harmful GHG emissions from a cluster of about 100 steel rerolling mills in Bhavnagar, a planned intervention was initiated by WII with support from International Centre for Environment Technology Transfer (ICETT), an entity of the Japanese Government working in collaboration with the global Climate Technology Initiative (CTI). During the current phase of the program, WII undertook the task of developing scientifically designed reheating system customized for the small-scale operation of these MSME units and demonstrating the profitable implementation of the designed system in a full scale operational rerolling unit.
Objective
The specific objectives of the project were two-fold: - To research, develop, implement and demonstrate the systems with lower specific energy consumption, lesser breakdown, increased productivity and reduced GHG emissions.
- To propagate the project outcome for replication of the developed technology.
Project Outcome/ Activities
The project outcome was determined by measuring the specific fuel/energy consumption by the modified system against the baseline specific fuel/energy consumption. The following results were obtained: - Reduction in specific fuel consumption by 30 percent from the baseline value
- Threefold increase in furnace efficiency
- Reduction in scale loss by 3.5 percent
- Improvement in environmental performance of the furnace by reduction in the emissions of SOx, NOx, SPM, RSPM and high temperature GHGs into the atmosphere
Apart from the technological impacts as mentioned above, the project has also been successful with regard to the following subjective impacts: - Efficient energy use has ensured the long term sustenance of small-scale rerolling mills in the cluster
- Change in industries’ perception towards cleaner production technologies, from non profitable and cost intensive ones to profitable and increased capacity ones
- Generation of enthusiasm among the stakeholders for further replication and improvement of the technology, specific to the needs of the cluster
- A roadmap has been developed for replication of the improved technology in other segments of the rerolling industry in the cluster so as to create a framework for sustained improvement and technology transfer in the smallscale rerolling sector
Participation Incentives
Vijay Steels, Bhavnagar was selected as a model unit for implementation of long-term energy conservation measures. These measures were researched and developed specifically for the unit by undertaking focused study and research on various operational parameters of the unit. The following specific activities served as important milestones during the project implementation: - Re-designing of the furnace for improved combustion and heating and waste heat recovery
- Erection and commissioning of new and modified systems in the model unit
- Performance evaluation and assessment of quantum of energy savings
- Organizing cluster level dissemination workshops and developing of a roadmap for further replication
