本文着重分析研究最近刚提出的并联型Brayton和Rankine联合循环——HAT循环。由于效率、环保及成本等优势,它将成为跨世纪的新颖热力循环。 一、HAT循环概念 图1为热力系统图。水在中冷器C_1、后冷器C_2及热水器H中加热升温后从饱和器S This article focuses on the analysis of recently proposed parallel Brayton and Rankine combined cycle - HAT cycle. Due to the advantages of efficiency, environmental protection and cost, it will become a novel thermodynamic cycle across the century. First, the HAT cycle concept Figure 1 for the thermodynamic system diagram. The water is heated in the intercooler C_1, the aftercooler C_2 and the water heater H from the saturator S after heating
