An experimental study on electricity generator emissions and their environmental impact in Kirkuk city

Abstract

This article evaluated the environmental impact of emissions from private electric generators, focusing on the amount of toxic gas they contribute to the surrounding environment. In the research, the number of generators used in the study was fifteen diesel-powered generators confined within specific residential areas in the city of Kirkuk (Iraq). The study included a field survey and measurements using air pollution standards. The amounts of HCl, H2S, SO2, NO2, NO, CO2, CO, O2, temperature, and relative humidity in the exhaust gases to illustrate the pollutants and compare them to the normal case were measured. It was found that the concentrations varied depending on the generators' parameters and they were high. The diffraction values were distinguished in location A4 (generator manufacturing company – Scania, generating capacity 250 kVA, voltage 200 V, number of residential units consumed - 500), which was characterized by higher concentrations of contaminants than in the standard case. In the remaining cases, this was due to a variety of factors, including the generator's operational age and the higher number of houses it served compared to its generating capacity, which exceeded its design limit.
