Energy Management Studies in an Engineering Industry

Abstract

As an M.Tech student of Energy Technology and Management course, engineering industry is joined where manufacturing process and surface platting occur. For doing these things, many energy resources are consumed. In order to save and use these energy resources, appropriate steps are suggested. Electrical, thermal and renewable energy sources are considered in this engineering industry. I had a chance of being an intern at Hero Cycles Ltd. Ludhiana during this training. After being a part of 10 days induction of the entire industry, many innovative ideas and suggestions were presented. These ideas and suggestions were necessary for energy saving projects and saving the wasted energy of the industry. Thereafter, many energy saving projects, which would be beneficial for the industry were proposed and implemented. Daily energy consumption data was prepared in a suitable format. Doing this, the energy consumption (before and after implementation of saving projects) was clearly understood. I had done many valuable and innovative energy saving projects (Electrical, thermal and renewable energy) in engineering industry. Main energy consuming device are motors in this industry. As behalf of this concept, specification of all motors is collected. After this, the present efficiency of motors are evaluated and compared with mentioned efficiency on name plate of motors, the convectional motors/ low efficiency motors were replaced with energy efficient motors. Some of the heavy motors, where damping valves are being used (like ASU, ID & FD fans of Boiler and Blowers), are connected with VFD (Variable Frequency Device) controller. Dip brazing is the process for robust and smooth joint of works. Lots of thermal energy is wasted. For reusing of this energy, an energy efficient design is architected. By this design, fuel is heated with this wasted energy rather than electrical heater. I had an attention on changing the fuel, LPG to Propane. This project was also completed in my supervision. For learning of boiler and its functions, I had formulated boiler’s efficiency. As well as electrical and thermal energy projects, Renewable energy projects are implemented. A small solar PV (photovoltaic) power system was established in industry in my supervision. Energy saving reading, calculating, energy flow diagram, energy cost is evaluated at daily basis. These above projects are useful and valuable for enhancing my knowledge and supervision. The theoretical and practical knowledge should be balanced.
