Energy Loss Analysis of Turbine in 200MW High Temperature Gas Cooled Reactor Nuclear Power Plant

采用能级效率法对200MW高温气冷堆核电机组的热力系统能损分析,特别是对各级加热器的能损进行了解耦分析。通过引入加热器的热耗影响因数,获得了VWO、TRL、75%TRL、50%TRL 4种工况下各级加热器对降低热力系统热耗的影响和变化规律。以上分析方法和结果,可以为200MW高温气冷堆核电机组的热力系统的设计、优化、运行和维护提供重要参考。

In this paper, energy loss analysis of thermal power system of 200MW high temperature gas cooled reactor nuclear power plant with the energy level efficiency method, especially for the energy loss deeoupling analysis of each heater. By introducing the heat consumption influence coefficient, the influence of each heater in reducing the heat consumption of thermodynamic system under the conditions of VWO,TRL,75% otTRL and 50% otTRL was obtained. The above results provide important reference for the design, optimization, operation and maintenance of the thermal system of 200MW high temperature gas cooled reactor nuclear power plant.
