Abstract
- Iron furnace gases, a byproduct of the steel and iron industries, have been the subject of research on employing them to power some of the factory's internal needs. The rise in fuel costs and focus on energy system sustainability have created distinct frameworks for heat loss sources and low-value fuels. In this study, iron furnace gas produced in steel and iron factories has been used to produce additional power to provide part of the domestic power consumption of these factories. The supercritical carbon dioxide cycle has been used to generate power. The results show that at the optimal point, the system has emissions of 0.52 and a net power output of 22100 kWh. Also, the system's efficiency is 38.56% and carbon dioxide emission is 0.510 tons/MWh. Also, by increasing the exhaust gas temperature by 150 degrees, it is clear that 2 MW of recycled heat can be obtained. Also, in this regard, the output work of the turbine has increased by 0.8 kW and increases the efficiency of the whole cycle by 31.5% to 37%. [ABSTRACT FROM AUTHOR]
