基于核能低温供热堆调节特性的基本热负荷确定方法研究

Determination method of basic heating load based on regulation characteristics of nuclear low-temperature heating reactors

基于低温供热堆季节性功率调节幅度分析,推导了低温供热堆基本热负荷系数与功率调节幅度及供热负荷的函数关系,并给出了我国严寒和寒冷地区以供暖为主的低温供热堆系统基本热负荷系数范围。通过与俄罗斯(含苏联)建设的低温供热堆核能供热站设计数据对比,检验了该基本热负荷系数范围的合理性,即在功率调节幅度为10%的条件下,以供暖为主的低温供热堆基本热负荷系数严寒地区可取0.30~0.45,寒冷地区可取0.45~0.60。以严寒地区某核能供热系统为例,计算了低温供热堆的设备容量、调峰热源容量并分析了非供暖期提高核能利用率的设计方案。

Based on the analysis of the seasonal power regulation amplitude of low-temperature heating reactors,the functional relationship between the basic heating load coefficient of low-temperature heating reactors and the power regulation amplitude and the heating load is deduced,and the basic heating load coefficient range of low-temperature heating reactor heating system mainly for heating in severe cold and cold zone in China is proposed.By comparing with the design data of nuclear heating plants with low-temperature heating reactors constructed in Russia(including the Soviet Union),the rationality of the basic heating load coefficient range is verified.When the power regulation range is 10%,the basic heating load coefficient of low-temperature heating reactors mainly used for heating can be taken as 0.30 to 0.45 in severe cold zone and 0.45 to 0.60 in cold zone.Taking a heat supply system equipped with a nuclear heating plant in severe cold zone as an example,the equipment capacity and peak heat source capacity of low-temperature heating reactors are calculated,and some design schemes for improving nuclear energy utilization rate in the non-heating period are analysed.
