Performance Evaluation Of Industrial Thermal And Electrical Systems

Abstract

Energy Audit is an essential task to assess the performance of the continuously operating thermal and electrical utilities. In this work both electrical and thermal utilities are assessed and the documentation of the results are produced. Trials of the utilities such as Chillers, Transformers, Compressors, Air handling utilities, Thermopac, Boiler, etc.., are conducted to acquire the data required for computation. In addition, billing analysis to validate the opportunity to increase the Power Factor and reduce the Sanction Load is carried out. Improving the efficiency of the Utility in the industries is a highly recommendable way to mitigate carbon emissions in the environment without compromising the quality of production. This in turn helps a country to retain its pace of GDP growth at reduce emission rates. Efficient utilities gives maximum output for the energy consumed, which reduces the load on the network. Furthermore, this contributes to reduce the overall load on the network. In addition, the number units of energy generated at the generating side also decreases which leads to reduction in fuel as well as carbon emissions. Microsoft Excel is used as a tool for computation. Standard prescribed equations from Bureau of Energy Efficiency to assess utilities are used to create tools in MS Excel for individual Utilities. Onsite measurement of the different parameters required for the assessment of the utility was taken. The measured parameters were used in MS Excel tool to compute the performance levels. Post assessment the results are compared with the standards to understand the % deviation in the performance and the root cause of it. Based on the observation and the mathematical conclusions changes are recommended to improve the performance with feasible monetary investments. Next, simple payback period is projected with respect to savings achieved after assessment. The assessment showed that the Energy Management in both the industries were significantly poor and energy saving opportunity is very high. After computation it is observed that the proposed monetary savings for the proposed investment needed to improve the utilities performance is feasible. In addition, it was found out that by implementing the recommendation given for these industries will mitigate Co2 emissions nearly 655 tonnes annually.
