核电机组对汽轮机末两级低压给水加热器安全可靠性的要求比火电机组严格得多。本文对该设备设计中热力参数的确定、结构设计、热力计算及材料选择等问题做了简明描述。
The requirements of nuclear power plants on the safety and reliability of the last two stages of low-pressure feed water heaters for steam turbines are much more stringent than the thermal power units. In this paper, the thermal parameters of the device design to determine the structure design, thermal calculation and material selection and other issues made a concise description.
