Comparison of thermodynamic performance and economic efficiency of ORC system for low temperature flue gas
摘要
Abstract
: This paper established the organic Rankine cycle ( ORC ) systems which utilized low-temperature flue gas as heat source to generate electricity. 2 Groups of single working fluids were researched. By changing heat source parameters to alter the heat absorption of the systems,the thermal equilibrium method was used to calculate thermal performance. Both thermodynamics and economics were taken into consideration to analyze the performance of systems with different working fluids. The result revealed that the two working fluids with the same group retained the similar parameters of network and heat consumption rate with the similar regularity of changes,while the LEC(levelized electricity cost)and DPP(discounted payback period)were not similar. Under the condition studied,the evaporation temperature optimized by economics was about 8—10℃ higher than that by thermodynamics. The comprehensive comparison showed that R600a was the best choice. The thermal performance of system using R236ea was better than R600,but the LEC of system using R600 was lower than R236ea. Compared to R236ea,R600 had obvious advantage at the aspect of economics.关键词
