Investigations On Gas Turbine Inlet Air Cooling Technology Based On Lithium Bromide Absorption Chiller With Heat Pipes

With the aim to probe into the issue on performances of the gas turbine combined cycle, appearing to be a drop whilst an increment of ambient temperature, a novel inlet air cooling technology for gas turbine combined cycle using exhaust heat was presented. Noteworthy, the refrigerating process on the exhaust heat recovery via Lithium Bromide absorption chiller with additional heat pipe outfit would be implemented to the reduction on the compressor inlet air temperature. The model for simulation of the combined cycle plant fuelled by natural gas was developed using the Aspen Plus software. Moreover, based on this model, the atmosphere temperature effect on the combined cycle performance was analyzed. And then, the calculation software for design of the new chiller was programmed with VB programming language. At last, the performance analysis of different working conditions and the technical & economic analysis were carried out. The results indicate that, with the gas turbine inlet air cooling system with heat pipe, the inlet air temperature makes an apparently decline from 10 to 15 centigrade, the power output of the GTCC increases remarkably and the inlet air temperature amplitude goes a steady increase accompany with increases in gas temperature.
