Experimental Investigation of Micro-Gas Turbine Performance at Reduced Air Inlet Temperature

Gas turbines have long been utilized as the main device for power generator. High temperature of ambient air flowing into inlet can reduce their performance. The objective of this study is to investigate the performance of a 1.5 kW micro-gas turbine at reduced inlet temperature using dry-ice as the...

It was recorded that increase power output of 8.5 achieved from reduction of temperature of 7.5.
