Abstract : This study identified various components of flue gas emission from small-scaled sound proof and locally coupled generators with different capacities. The analysed gases included methane (CH4), nitrogen dioxide (NO2), carbon monoxide (CO), Sulphur dioxide (SO2), hydrogen sulphide (H2S) and ammonia (NH3). The noise level and volatile organic carbon (VOC) were also analysed. The capacity of soundproof generators ranged from 20 to 60 KVA, while that of the locally coupled generators ranged from 7.5 to 10 KVA. The distances of the generator exhaust and the point of analysis ranged between 1m and 10m. The results indicated that the generators (locally coupled or sound proof) have greater influence on the emission rate gases, but the soundproof generators slightly released more gases than the locally coupled generators due to aging. For instance, the concentration of CO emitted from the soundproof generators at 1m distance ranged from 2 – 26 ppm, while for the locally coupled generators, it ranged from 8 – 15 ppm. The average value of 95.7Hz, from locally coupled generators shows that soundproof generators are better in sound pollution with an average value of 80.26H2. Generally, generators used beyond 7yrs have higher rate of gaseous emission.
