摘要
结合了模块式高温气冷堆与气体透平循环技术的高温堆气体透平循环是核电领域中的全新概念,为提高核电的安全性和经济性提供了新的思路,具有很强的竞争优势。其中,高温气冷堆回热循环是该方案的主流。在高温堆回热循环方案中,氦气透平机组的工作介质为氦气,其物性与空气有很大的不同,因此,氦气透平与燃气透平在热力参数、气动参数、尺寸、级数等方面有着较大的差别。本研究对回热循环以及氦气透平进行了初步分析,并通过与燃气透平的比较,揭示了回热循环与氦气透平的一些基本设计特点。
In the high temperature gas-cooled reactor (HTGR), gas turbine cycle is a new concept in the field of nuclear power. It combines two technologies of HTGR and gas turbine cycle, which represent the state-of-the-art technologies of nuclear power and fossil fuel generation respectively. This approach is expected to improve safety and economy of nuclear power plant significantly. So it is a potential scheme with competitiveness. The heat-recuperated cycle is the main stream of gas turbine cycle. In this cycle, the work medium was helium, which was very different from the air, so that the design features of the helium turbomachine and combustion gas turbomachine were different. The paper shows the basic design consideration for the heat-recuperated cycle as well as helium turbomachine highlights its main design features compared with combustion gas turbomachine.
