本文计论在双流体循环中应用辐流式汽轮机的技术经济意义。对汽轮机效率及主要设计参数选择进行了综合分析,介绍研试机组结构、制造特点和试验方法。通过实验,证明辐流式汽轮机具有结构简单、加工容易、效率较高和成本低等特点,比较适应于低沸点介质循环的中、低焓降和大流量的要求及中低温地热发电的中、小功率的特点。文中还说明在其他热水资源(余热及太阳热)发电中应用这种汽轮机的前景。
This article discusses the technical and economic implications of the application of a radial-flow turbine in a two-fluid cycle. The turbine efficiency and the main design parameters were analyzed comprehensively, and the structure, manufacturing characteristics and test methods of the test generator were introduced. The experiment proves that the radial turbine has the characteristics of simple structure, easy processing, high efficiency and low cost. It is more suitable for medium and low enthalpy drop and large flux of low boiling point medium circulation and medium and low temperature geothermal power generation, Low-power features. The paper also shows the prospect of applying such turbines to other hot water (waste heat and solar thermal) power generation.
