Design and Experiment Research on Organic Rankine Cycle (ORC) Power Generation System
摘要
Abstract
Based on the premise of recycling the low-temperature waste heat from a 90-150 ℃ source,a test bench was designed for an organic Rankine cycle power generation system,and experimental research was performed.The effects of the evaporating temperature on the expander performance and system performance were investigated by adjusting the inlet pressure of the turbo expander and the evaporation temperature.The experimental results showed that when the evaporation temperature increased from 76 ℃ to 84 ℃,the expander inlet temperature gradually increased.Thus,the expander speed increased by approximately 9.11％,the output power increased by 1.26 kW,and the highest isentropic efficiency was 80.6％.At the same time,the cycle net power,thermal efficiency,irreversible loss,and exergy efficiency increased with the evaporation temperature by 33.9％,26.7％,15.4％,and 27％,respectively.关键词
