Fuel Substitution for Energy Saving: A Case Study of Foundry Plant
Foundry based organizations consume significant amounts of energy for producing their final products. Recently, techno-commercial and environmental factors have started triggering change from fossil fuels to cleaner ones. In this paper, factors acting as driving forces for migration from one fuel to another in order to improve energy efficiency, including various performance parameters in support of environment preservation, have been identified. Focus is also given to challenges which encounter during fuel switching. A new framework has been applied that can be used for fuel switching in manufacturing organizations. A real case of switching from three types of fuels to a single fuel has been studied and the outcomes are evaluated. Analysis related to energy consumption before and after fuel switching with respect to corresponding production data have been performed.
