摘要

本文在13．0MPa～27．0MPa的宽广压力范围内，对d28×6mm的12Cr1MoV垂直上升四头内螺纹管的壁温特性进行了试验研究，试验在国产600MW超临界锅炉水冷壁变压运行参数范围内进行，着重研究管壁温度随压力、质量流速、热负荷和工质烂的变化规律，为超临界变压运行锅炉的设计和运行提供了可靠的数据。

Abstract

In the range of pressure from 13MPa to 27MPa

Wall temperature characteristics in a vertical upward four - heads ribbed tube made of 12Cr1MoV with a diameter of φ= 8 ×6mm are experimentally studied. The experimental Parameters are in the range of sliding w pressure operation for 600MW supercritical pressure boiler’s water wall. The law of wall temperature distributions and the effects of pressure

mass velocity

heat flux and enthalpy are analysed in detail. The results are very helpful for the design and operation of supercritical sliding- pressure operation boiler.
