“…(1) Save energy. On the one hand, compared with the 30-45% energy utilization rate of typical large-scale power stations, the tri-generation system can realize the cascade utilization of energy, which can be utilized according to the different temperatures of the medium, so as to reduce the available energy loss of the system as much as possible [8]. The final total energy utilization rate can reach 70% or even more than 90%.…”

“…6,7 In the past decades, several approaches have been developed for low-grade heat utilization, such as the organic Rankine cycle, Kalina cycle and thermoelectric generators, etc. [8][9][10][11] However, these technologies still face several challenges including the huge size and weight of thermodynamic cycle systems or the low Seebeck coefficient of thermoelectric materials. 12,13 Signicantly, the thermo-electrochemical cell (TEC) is a technology that generates electricity through temperature-dependent redox reactions occurring at the surface of electrodes, with a Seebeck coefficient typically in the order of mV K −1 .…”

“…In recent years, the ORC and Kalina cycle have drawn much attention and been applied in geothermal power generations [1][2][3][4][5][6][7]. The Kalina cycle system can use low-temperature energies with higher cycle efficiency than those of ORC cycles [3,8] since it uses ammoniawater as the cycling medium with variable boiling and condensation temperature.…”

Multipoint Design Optimization of a Radial-Outflow Turbine for Kalina Cycle System Considering Flexible Operating Conditions and Variable Ammonia-Water Mass Fraction

et al. 2022

The radial-outflow turbine has advantages due to its liquid-rich gas adaptability when applied in the Kalina ammonia-water cycle system. However, the operational conditions of the turbine often deviate from its design values due to changes of the heat source or the cooling conditions, and such deviates may deteriorate the flow behavior and degrade the turbine performance. To enhance the turbine efficiency at complex conditions for flexible running of the Kalina cycle system, a multipoint design optimization method is developed: the flexible operating has been defined by three critical, dimensionless parameters, which cover a wide range in a 3D operating space; the representative off-design points are identified to define the objective function; and adaptive optimization methods are integrated to permit optimization searching using limited CFD callings. The developed multipoint design method is adopted to improve the turbine performance under complex operating conditions. The obtained results demonstrate that the application of the developed multipoint optimization method effectively eliminates the flow separation at various operating conditions; thus, the turbine off-design performance has been comprehensively improved.
