Organic Rankine cycle system with supercritical double-expansion and two-stage heat recovery

摘要

The present invention discloses an Organic Rankine cycle system with supercritical double-expansion two-stage heat recovery, comprising a first-stage evaporation cycle system, a second-stage evaporation cycle system and a mixing system. The present invention has lower heat loss in the heat exchange process, better heat exchange effect and improved utilization efficiency of waste heat.
