Exhaust system performance optimization of the domestic electric generating plant

Abstract

Sound is a common part of everyday life, but when a sound is unwanted, it is considered noise. When
noise in a room is at unacceptable levels, it can be an annoyance, distracting the occupants and in
industry, it results in higher stress levels and decreased productivity. In this study, an exhaust/silencer
system, that is capable of reducing exhaust noise, was fabricated for use in a domestic generator.
Experiment was carried out with the factory fitted silencer and the fabricated silencer. The fabricated
exhaust system was able to reduce noise of 8.06% compared to 4.16% obtained with the factory fitted
silencer. Also, the fuel consumption rate of the generator is lower when the fabricated exhaust system is
used. This showed that (in the long-run) the new exhaust system would efficiently serve as alternative to
the old system.
