Experimental analysis of circulating water flow rate on performance of ORC waste heat power generation system
摘要
Abstract
Experiment was made to comprehensively analyze the effect of circulating water flow rate on organic Rankine cycle (ORC) waste heat power generation system based on a 3 kW experimental prototype in laboratory. Considering circulating water as energy transfer medium, the energy consumption analysis was carried out by the total energy system method, and the performance of system and main equipment with different heat source temperatures was evaluated. The results showed that the output power of generator, expander and ORC subsystem increased with the increase of heat source temperature and circulating water flow rate, as well as the thermal efficiency and exergy efficiency of ORC subsystem. The maximum values of net output power and exergy efficiency of system were obtained under the same conditions. As the temperature of heat source is 120℃and the circulating water flow rate is 1.629 t·h-1, the maximum values of net output power and exergy efficiency of the system are 0.731 kW and 11.81%, respectively. This study provided references for performance analysis of ORC waste heat power generation system with different boundary.关键词
