TY - JOUR TI - Concerning utilization of heat from low-potential sources AU - Alekseenko Sergey V AU - Ogurechnikov Lev A JN - Thermal Science PY - 2019 VL - 23 IS - 6 SP - 4023 EP - 4030 PT - Article AB - The possibility of using R245fa and n-pentane in the Rankine cycle to convert the heat of low-potential sources into electrical energy is analyzed. A multistage axial-type turbine is considered as a drive of an electric generator. The influence of initial pressure of working fluids on the efficiency of the expansion process is determined. The algorithm and characteristics of thermal calculation of the turbine are given.
