For the experimental verification of the effect of adjustable compressor inlet guide vanes combined with adjustable turbine outlet guide vanes for reducing the fuel consumption at idling, an 8 kW test gas turbine was designed and built up. The data of the experiments with the test gas turbine was compared with experimental data acquired by the author from another gas turbine. Additionally, experimental data was compared with external data of other heat engines. Using the newly introduced dimensionless Kruschik number, the test gas turbine, two series gas turbines and an internal combustion engine was compared in terms of their required heat supply at idling.
