TWO STAGE REGENERATIVE ORGANIC RANKINE CYCLE (ORC) HEAT RECOVERY BASED POWER GENERATION SYSTEM

摘要

Embodiments disclosed herein provide a two stage regenerative ORC heat recovery based power generation system (200). The power generation system (200) includes an organic fluid pumped at one of HP and LP. A LP pump circulates the organic fluid through the power generation system (200). Further, the power generation system (200) includes first loop performing supercritical evaporation (206) of the organic fluid to obtain supercritical vapor of the organic fluid and a second loop for obtaining sub-critical vapor of the organic fluid. Further, the power generation system (200) includes two stage expander generating power from trans-critical expansion of organic fluid by converting mechanical energy of two stage expander into electrical energy, energy is recovered from superheated vapor resulting from trans-critical expansion of the organic fluid and a condenser (205) is used for condensing the superheated vapor of the organic fluid into saturated fluid after generation of power.
