首次将强度测温法应用于标准联合循环中压汽轮机热转子表面温度的现场测量。数据包括冷启动和从基本负载冷却。将测得的温度与静态汽轮机部件的标准温度测量结果和在热井上测得的上游蒸汽温度进行了比较。报道了如何评估高温测量在汽轮机中的适用性。详细介绍了新开发的用于测量蒸汽透过率的USC高压灭菌器，以及转子金属发射率的测量。此外，还展示了开发蒸汽高温计的步骤；它是如何开发的，在热蒸汽环境下的精度和寿命方面进行了验证，以及它是如何准备与标准涡轮机集成的。版权所有：2012，阿尔斯通技术有限公司。
The first-in-time application of intensity pyrometry to measure in-situ the hot rotor surface temperature of a standard, combined cycle, intermediate pressure steam turbine is presented. The data cover a cold-start and cooling from base load. The pyrometric temperatures are compared to standard temperature measurements on static turbine parts and an upstream steam temperature measured on a thermo well.It is reported, how the applicability of pyrometry in steam turbines was assessed. Details are given about a newly developed USC autoclave, which was used to measure steam transmittance, and about the measurement of the emissivity of the rotor metal.Further the steps taken towards a steam-pyrometer are shown; how it was developed, validated in terms of its precision and lifetime in hot steam environment, and how its integration to a standard turbine was prepared.Copyright © 2012 by Alstom Technology Ltd.
