摘要

随着超超临界机组温度、压力参数的提升

对热电偶测量高温高压介质温度及其可靠性提出了更高的要求。为此

从热电偶的选型、保护管材质的选择、插入深度、工艺管道的焊接、保温等方面提出了相应的措施。

Abstract

Along with the temperature and pressure parameters of ultra-supercritical(USC) units being significantly raised

more higher requirments for thermocouple and its reliability have been put forward.For this

the basic measures for enhancing the reliability of thermocouple temperature measurement of USC units from several aspects

such as thermocouple selection

material selection of thermowell

inserted depth

pipe-welding technology

and heat-preservation

etc.have been proposed.
