Energy Audit in Casting Industry

Energy Audit in Casting Industry
Energy today has become a key factor in deciding the product cost at micro level as well as in Casting Industry. Energy cost is a significant factor in economic activity at par with factors of production like capital, land and labor. Energy Audit attempts to balance the total energy inputs with its use and serves to identify all the energy streams in the systems and quantifies energy usage’s according to its discrete function. Energy Audit helps in energy cost optimization, pollution control, safety aspects and suggests the methods to improve the operating & maintenance practices of the system. It is instrumental in coping with the situation of variation in energy cost availability, reliability of energy supply, decision on appropriate energy mix, decision on using improved energy conservation equipment’s. instrumentation’s and technology. Energy audit is a vital process, which enables a comparative estimation of future energy efficiency improvements. In energy conservation project a systematic audit ensures that every opportunities of benefiting from project synergies are explored.
