Energy Saving in A Glass Bottle Manufacturing Plant

摘要

Energy saving is very essential in the present scenario for all industries. Global warming and higher carbon footprint is resulting in climatic changes across the world. In a glass bottle manufacturing plant, compressed air system is very critical for getting good quality bottles. Leakages and pressure drop are the main cause for energy loss in compressed air system and it increases the percentage of defective bottles. The objective of this work is to save the energy by reducing the pressure drop and thus reducing the percentage of defective bottles manufactured due to insufficient pressure. In a glass bottle manufacturing plant in Pondicherry, high-pressure lines and low-pressure lines are used for forming various size bottles. Annual energy consumption, leakage percentage and the energy loss of the existing arrangement of compressed air system were calculated with the measured data. The pressure drop in the system was reduced by modifying this system by adding a secondary air receiver. The annual energy consumption leakage percentage and energy loss are calculated for modified arrangement at the same operating pressure and increased operating pressure. On analysis, it is found that energy loss is reduced by 18.1% in the modified compressed air system.
