超超临界电厂热工仪表导管阀门的设计选型研究

Design and Type Selection of Pipes Valves of Thermal Instrument in Ultra-supercritical Power Plant

超超临界机组高温高压参数对热工仪表导管阀门提出了更高的要求,目前国内在这方面还没有现成的标准规范可循,给热工仪表导管阀门的选用带来了一定的困难,本文针对超超临界参数,结合以往工程经验并通过分析计算,确定了热工仪表导管阀门的选型规格。通过研究,希望为超超临界机组的热工测量仪表导管阀门的设计选型提供依据,保证电厂的安全可靠运行。

High temperature and pressure of ultra-supercritical power plant makes higher requirement for IC pipes and valves,which also brings some difficulty on IC pipes and valves design for lack of criterion.The paper presents a method on IC pipes and valves design for ultra-supercritical plant base on experience and calculation.It is hoped that it can give some help on IC pipes and valves design to ensure plant safety and reliability.
