Studies on energy conservation aspects in industrial compressed air supply systems

Abstract

Need to conserve the natural resources and environment has shifted newlinethe focus on conserving energy in all domains The present work aims to newlinereduce energy usage in industrial compressed air supply systems by various newlinepossible means Compressed air is used in almost all sections of industry In newlinethe recent years as industries are moving towards automation the compressed newlineair usage is also increasing It has found that electricity usage accounts for 10 newlineto 70 of total electricity in industries Studies have shown that there exists newline15 to 50 energy saving potential in the industrial compressed air systems newlineA review of available literature has shown that i considerable newlinepotential exists for saving energy in industrial compressed air systems newlineii reducing the delivery pressure settings and pressure bandwidth are found newlineto offer considerable energy savingsiii variable frequency drives are found newlineto be advantageous in certain casesiv uncertain variations in compressed newlineair usage makes the user to set the higher delivery pressures newline newline
