Sažetak
Combined-cycle power plants use fossil fuels as an energy source and account for a significant share of global electricity generation. They represent the one of the most efficient energy conversion technology and the most sought-after option for meeting the world's growing electricity consumption. The aim of this research is to model an integrated gas-, steam- and absorption refrigeration cycle combined power plant with the combustion of syngas, instead of with conventional fossil fuels, integrating a coal gasification cycle into it. Performance analysis of the overall IGCC plant with cogeneration and absorption cooling will be performed by changing the parameters of gasification and combustion, input fuel type (coal) and introducing two-stage compression with one and two intercoolers in the combined cycle. Improvements in efficiency were observed by applying two-stage compression with two intercoolers as well as increasing gasification pressure. The obtained results are compared with the basic model when the IGCC one-stage compression plant operates at full load using Tuzla lignite as fuel.
