A Study on Global Warming Effect of Combined Cycle Power Generation Process

Abstract

In this paper, global warming effects of the Al-Musaib thermal power plant in Iraq was inspected. In this regard, two system models for power generation were taken into consideration while accounting for the necessary assumptions.<br><br>The two models are (i) simple cycle steam turbine power generation in the first model and (ii) combined cycle power generation. According to the outcomes of the indicator study, model 2 produced the best results. As a result, the total waste exergy ratio decreased from 79.24% to 68.86%, the environment effect factor decreased from 3.824 to 2.216, the exergetic sustainability index increased from 0.262 to 0.451 and the global warming effect decreased from 0.804 gCO2e/kWh to 0.616 gCO2e/kWh. Based on the results of the analysis, it can be concluded that model 2 is an eco-friendly, long-lasting, and low-emission (global warming effect) system that can be a useful reference for the Al-Musaib thermal power station in Iraq. As a result, it can be said that a system like this may be employed to increase environmental sustainability while reducing the effects of CO2 driven global warming.
