JK LAKSHMI CEMENT LIMITED
Bureau of Energy Efficiency (BEE) in partnership with Institute of Industrial Productivity (IIP) has established a Knowledge Exchange Platform (KEP) to promote transfer and uptake of best practices and technologies in industries covered under the Perform Achieve and Trade (PAT) scheme. As part of its mandate, KEP has organized various sector level best practice exchange workshop, technology exhibitions, policy discussions, exchange visits, communication and other outreach activities, which has been helping the industries in meeting their objectives of achieving energy efficiency.
As PAT is moving into second and subsequent cycles of implementation, the targets for energy efficiency at industry level are expected to become challenging, more so, for the cement sector. KEP has always tried to improvise its strategy to meet the continuously changing needs and requirements of the industry with regard to achieving energy efficiency and with this mandate KEP is providing value added services for training and capacity building of the industries under the SPARC model (Service Package for Advancing Resource Conservation). The whole idea behind organizing such training programs is that, with the enhanced target under the PAT scheme in each cycle the industry will need much more customized and hand holding support to identify their plant specific opportunities for energy efficiency. The two days training and capacity building workshop was organized at JK Lakshmi Cement Limited, Durg plant on 6th and 7th June, 2017 which was attended by 22 officials working in mechanical, electrical, instrument and process departments
The workshop was organized to achieve the following objectives:
1. To create awareness in the plant personnel at operational level on various provisions of PAT scheme, international standards and energy management approaches such as ISO 50001, Total energy management approaches etc. – the challenges and opportunities
2. Identify and assess plant specific opportunities and potential for achieving energy efficiency under PAT scheme (2nd and subsequent cycles)
3. New, cutting edge and innovative technologies on Thermal & Electrical efficiency suitable for the specific to the plant operations.
4. Build the capacity of the plant personnel to handle the operational and technical aspects of implementing new energy efficient technologies and approaches.
The welcome address was presented by Shri Ashish Sharma, Sr. Manager (HR), JK Lakshmi Cement Limited. He welcomed Shri Mukul Srivastava, Vice President; Shri Sanjay Sud, Senior General Manager- Electrical; and KEP faculty, Shri Nagesh Kumar and Shri K. K. Chakarvarti. In his address he highlighted the contribution made by KEP in promoting energy efficiency in Indian Industry and hoped that under KEP-SPARC membership, Durg plant will also be greatly benefitted through the proceedings of 2 days’ Training and Capacity building program followed by 3 days’ Small Group Activity program.
The workshop was inaugurated by Shri Mukul Srivastava, Vice president (Engineering), JK Lakshmi Cement Limited, Durg. In his inaugural address, Shri Srivastava mentioned that the participants of this capacity building program are young engineers and are willing to learn new methods and techniques to improve plant energy performance. He thanked the Corporate office in supporting this initiative and felt that energy saving opportunities will be identified by the participants with the support and inputs provided by the faculty from Knowledge Exchange Platform (KEP).
Shri K.K. Chakarvarti, Expert Consultant, and Shri Nagesh Kumar, Expert Consultant, while giving the introduction to the workshop, in the inaugural session explained the participants about the importance and need for capacity building of plant engineers. Shri Chakarvarti pointed out that development of 98 Smart Cities are expected to provide a major boost to the sector and cement demand is expected to touch 550 million tonne by 2025. This may also raise the energy requirement of the sector to 41 million tonne of oil equivalent energy (mtoe). This may be a big challenge for the entire sector and therefore calls for rational use of energy and consistent improvement in energy performance indicators.
Dignitaries at the inaugural of the capacity building program
Before beginning the technical sessions of the workshop, Shri Sumit Ganguly, DGM (Production), JK Lakshmi Cement Limited, Durg, provided an overview on the design and operation of different processes and utilities in the plant so that the participants could keep the plant specifications and needs in perspective while understanding and relating with the suggestions/ opportunities identified in the technical sessions.
The two day workshop was divided into 8 technical sessions carefully designed to meet the plant specific needs. The first technical session was focused on providing an overview to the participants on energy management and approaches and how they relate with the PAT scheme. It covered various EnMS approaches like ISO 50001, standards, energy audits etc., which could help industries not just achieve some of the international standards and continuously improve their energy performance but also meet their PAT targets.
The 2nd technical session was focused on Fuel and combustion systems covering the aspects of optimizing these operations in Cement Kiln as well as achieving heat balance of kiln. The 3rd session covered electrical systems specifically focused on transformers, how to avoid distribution loss and power factor improvement. Electrical motor efficiency is increasingly becoming important for enhancing the overall energy performance of any plant. BEE is also advocating the use of energy efficient motors viz. IE3, IE4. The session therefore focused on energy efficiency issues and conservation aspects with regard to electrical motors. The resource persons (Shri Chakarvarti and Shri Nagesh Kumar) illustrated this through various case studies and examples.
The fourth technical session on Day 1 was focused on energy efficiency of utility systems particularly the pumps, pumping system and VFDs. In this session also the participants were provided practical understanding of these aspects through case studies.
The second day was designed to cover four technical sessions. The first and second technical session was focused on enhancing electrical savings in compressors and compressed air systems which was illustrated through both technical options as well as how they can be implemented through practical examples. The third technical session covered the energy efficiency improvement in electrical systems such as fan systems and cooling towers. The potential for energy savings in these utility areas was explained through case studies. The last technical session covered the best practices and case studies of successful applications (avoiding the pressure drops in dampers fitted in fans which are already provided with VFDs, restricting the false air infiltration in preheaters, optimizing the operation of coal firing blowers, increasing the efficiency of preheater top cyclone, reducing the pressure drop in preheater down comers etc.) and how the power can be saved, explained through relevant case studies. Detailed discussions were held with the participants to explain how these best practices can be implemented in plant’s context.
Participants during the 2 Days’ Training & Capacity Building workshop
Shri D. K. Mehta, Plant Head and Sr. Vice President (Works), along with Shri Mukul Srivastava, Vice President (Engineering) interacted with the participant in the concluding session of Capacity Building Program and was pleased to note the positive feedback of the participants. He mentioned that this is a good opportunity for plant engineers to strengthen their capacity building on energy cost reduction and thanked the corporate office for taking this initiative through KEP. Shri Mehta mentioned that opportunity for saving energy is always there and we need to identify the areas for improvement. He said that the case of a fan fitted with VFD and Raw meal Silo aeration system, blowers, where participants have identified the energy saving opportunities. He urged the participants to take up more initiatives during SGA activity so as to utilize the knowledge gained in the capacity building program.
The workshop was concluded with a feedback session where the participants were requested to provide their inputs/suggestion for improving and enhancing the effectiveness of such in plant training and capacity building programs.
