Evaluation of NOx, SO2, CO and total greenhouse gases, emissions for thermal power plant units using natural gas and heavy fuel oil

Abstract

The environmental situation has become increasingly worrisome, even as great progress has been made in social and economic development. The objective of this study is to measure atmospheric emissions, NOx, SO2, CO, from thermal electricity generation. In this paper, a comparison greenhouse gases emission (CO2, N2O and CH4) (in terms of emissions factor) was carried out between thermal cycle for both natural gas and heavy fuel-oil consumption. Emission of flue gases were conducted for thermal power plant with the total installed capacity of 600 MW over the period 2011-2014 with regard to the power plant' operation characteristics including fuel type. The emission of NOx, SO2, CO and Greenhouse gases emission (CO2, N2O and CH4) emissions were found to be 357.55µg/m 3 , 2854.92μg/m 3 , 122.56µg/m 3 and 432036.4 Ton CO2 Eq. The emission factor was calculated Greenhouse gases emission (CO2, N2O and CH4) emissions was1420.75 g CO2 Eq/KWh -1 According to this comparison, emission of flue gases emitted from the thermal power plant will experience an intensive decline if heavy oil is replaced totally with natural gas, power plants' efficiency is increased and continuous emission monitoring systems and power plant pollution reduction systems are utilized..
