摘要:
本文针对压缩空气储能系统恒压运行会存在较大的压力损失,提出了一种新型喷射增效压缩空气储能系统,采用两级喷射器引射膨胀机做功后的乏气,回收部分压力能的同时增加膨胀机进气流量,从而提高系统的发电能力。建立新系统热力学模型,与相同运行参数下传统系统进行性能对比,并深入探究两级喷射器工作流体压力、引射流体压力以及中间压力对系统性能的影响规律。研究结果表明,当工作流体压力、引射流体压力以及中间压力升高时,系统全周期循环效率均呈近似抛物线变化趋势,进一步得到喷射器最佳工作参数;在最佳工况下,系统全周期循环效率为63.32 %,与传统节流降压方式循环效率为62.41 %相比,提升了0.91 %。根据以上研究,本文为喷射增效压缩空气储能系统减少节流损失、提高性能提供了理论依据。
