Abstract:
A schematic diagram and description of the ORC installation incorporating a single turbine will be presented for the case where the saturated dry vapour is produced in evaporators with an internal circulation of the individual energy carrying fluids. In the case of the heat sources of different temperature the internal circulation coefficients of the evaporators can be selected for each energy carrying fluid in such a way that the saturated dry vapour at the outlet of evaporators will have equal values of pressure and temperature. An algorithm of calculations will be also presented to enable the determination of the output power and efficiency of the power plant that works according to the subcritical Clausius-Rankine cycle. Calculation results will be shown for the cases of one, two and three energy carrying fluids of different temperature. On that basis, final conclusions will be given in respect to the possibility of application of the heat sources of different temperature to co-fuel the ORC power plant.
