Dual Recuperated SCO2 Brayton Cycle for Waste Heat Recovery from Gas Turbine

为研究双级回热SCO2布雷顿循环回收燃气轮机废热发电性能,建立相关的分析模型,分析压缩机入口温度和压力、透平入口压力对净输出功率的影响。结果表明:透平净输出功率随着压缩机入口温度和压力的提高而单调降低,随着透平入口压力的提高而单调增加。

To research the performance of Dual Recuperated SCO2 Brayton Cycle for waste heat recovery from gas turbine, a math model was established. Particularly, the effects of several key parameters, such as intel temperature and pressure of compressor and total pressure loss, on the net output power were analyzed. Results showed that the net output power decreases monotonically with the increase of the inlet temperature and pressure of compressor. While the elevated inlet pressure of the turbine results in a monotonically increase in the net output power.
