Energy Analysis of Non-Ferrous Piston Foundry - a Case Study

Abstract

The whole world is passing through an acute energy crises . The situation is going to worsen in the near future because the finite quantity of fossil fuels are fast exhausting . With the development of science and technology the manual work is being replaced by machines thus increasing the demand for energy . While on one hand the effects are on to produce more energy through conventional and non-conventional sources , it is necessary , on the other hand , to use the available energy in the most efficient way and conserve it Before we apply any conservation measures , it is necessary to know how much energy should be theoratically used and how much is being used with a breakup of energy consumption at various level . Energy analysis is the technique for examining the way in which the energy sources are harnessed to perform useful functions. In this study energy analysis of a non-ferrous piston foundry has been conducted . All inputs and outputs of energy and matherials for a period starting January 86 , have been collected . The system has been divided into various sub-systems and energy consumption of each type of piston blank in each sub-system have been calculated . From the manner the sub-systems are linked to each other the total energy consumption of type of piston blank has been calculated. The total energy values , thus calculated , are critically examined and areas of wastage have been found out. Ways and means are then suggested to avoid or at least minimise the energy wastage . Scope for further study has also been given.
