摘要

为研究超超临界锅炉水冷壁的动态特性

在沿高度方向热负荷分布不均的情况下

建立了某1 100 MW超超临界锅炉水冷壁的动态仿真模型

通过模拟得出了沿高度方向水冷壁的工质温度和金属壁温分布

分析了在水冷壁入口流量阶跃扰动时工质主要热力参数和壁温的动态响应特性。结果表明:50% THA (汽轮机热耗率验收)工况下

37.5 m高度处工质干度达到0.994

内壁面温度最高达到466.1℃;30% THA下

42.0 m高度处内壁面的峰值温度达到375.3℃;流量阶跃量越大

动态响应时间越长

同时会加剧传热恶化

蒸干区域的壁温升高;50% THA下

流量阶跃降低5.0%后

36.0 m高度处壁面温度最高会达到547.9℃

未发生超温现象;在流动稳定后

相较于设计流量

当流量分别阶跃降低2.5%和5.0%时

在50% THA下34.5 m高度处

内壁面温度分别提高5.6和17.2 K。

Abstract

In order to study the dynamic characteristics of the cooling wall in the ultra-supercritical boiler

a dynamic simulation model of the cooling wall in a 1 100 MW ultra-supercritical boiler was established under the condition that the heat load distribution along the height of the cooling wall was uneven. The distribution of the working fluid temperature and the metal wall temperature along the height of the cooling wall were simulated. The dynamic response characteristics of the main thermodynamic parameters of the working fluid and the metal wall temperature were analyzed when the flow rate at the cooling wall inlet was step-disturbed. Results show that under the design condition of 50%THA(turbine heat acceptance)

the dryness of the working fluid at the height of 37.5 m in the cooling wall reaches 0.994

and the inner wall temperature reaches up to 466.1 ℃. At 30%THA

the peak temperature of the inner wall at 42.0 m reaches 375.3 ℃. The larger the flow steps

the longer the dynamic response time is

the heat transfer deterioration is aggravated

and the wall temperature in the evaporation and drying region increases. At 50%THA

after the flow step is reduced by 5.0%

the wall temperature at 36.0 m reaches 547.9 ℃ in this process

and no overheating occurs. After the flow stability

compared with the design flow

when the flow step is reduced by 2.5% and 5.0%

the inner wall temperature at 50%THA and 34.5 m will be increased by 5.6 and 17.2 K respectively.
