The study analyzes the theoretical gain of the gas turbine inlet cooling system using a single absorption double-effect lithium bromide chiller based on real climatic data and gas turbine technical parameters, and through rational logical analysis and calculations, using the annual fuel savings ΣB as the criteria. The calculation uses the technical parameters of UGT 10000 (NISO =10.5 MW) to derive the optimal design value and the corresponding gain of the intake air cooling system. The results show a fuel saving of 26,359.2 g per 1 kW power output of the unit in year-round operation, for a total annual fuel saving of 354.6 t.
