Abstract

This paper describes the literature review of a Design And Development Of Industrial Generator Silencer. Diesel engine generator sets in heavy industry plants and residential/official buildings can cause serious noise problems. Diesel generators are used very commonly in shops, offices and in industry, today in order to supply power during power shutdowns .Exposure to noise causes detrimental effects on neuroendocrine, cardiovascular, respiratory and digestive systems. Chronic exposure to noise causes fatigue and interferes with concentration, thus reducing work efficiency. Experimental studies on the assessment and control of near-field noise levels due to the operation of a generator were undertaken by employing ant vibration mounts (made up of rubber, polyurethane foam, wool– felt).The enclosure of generator is made up of CRCA sheet of 2mm thickness and use Polyurethane foam of 25mm thickness inside the enclosure which reduce noise level. The muffler is made up of CRCA sheet of 1.2mm thickness, inner assembly is made up of same material. The generator muffler is enclosed with 3mm thick wool-felt for better sound absorption and thermal resistant. The wool-felt reduce the noise level 2dB(A). Silencer is installed to reduce noise where large quantities of high pressure air or gas are discharged into the open air. In this paper CFD analysis technique is used to modify the existing geometry of silencer.
