Comments on “Experimental study of flow boiling of FC-72 in parallel minichannels under sub-atmospheric pressure”

Results of experimental investigations of the ORC power plant operating with R227ea as the cycle working fluid are presented. The ORC power plant was fuelled with hot water of the temperature ranging from 66 °C up to 111 °C, at the maximum volume flow of 106 L/min. The ORC research installation was provided with a hermetic turbogenerator of special design to run at 3000 rpm in the nominal operating point. Detailed scheme of the research installation together with the measurement points locations are presented in the paper. The experimental results are supported by relevant calculation results that include an analysis and discussion of the quantities affecting the ORC power plant operation.
