Theoretical thermodynamic analysis on resorption power generation and pumpless ORC

Description
Resorption power generation cycle (RPGC) has been theoretically investigated and compared with pumpless organic Rankine cycle (PORC). The PORC operates without a liquid pump in conventional ORC and shares the similar configuration with RPGC. Three different organic fluids (pentane, R123 and R245fa) used in PORCs and four different reactant salts (manganese chloride, strontium chloride, barium chloride and sodium bromide) used in RPGCs have been analysed and evaluated in terms of the power generation capacity, thermal efficiency and energy density under the conditions of heat source temperature from 60 °C to 180 °C and heat sink temperature at 30 °C. The RPGCs have been analysed at ideal equilibrium conditions. Resorption power generation system using a pair of two same salts has been studied for the first time.
