| 摘 要： | 为了实现炉膛出口烟气温度的实时在线监测,在前期工作的基础上研发了单路径声学高温计,并首次在国内某300 MW电站锅炉中安装.经过冷态调试、热态试验和长期运行,验证了单路径声学测温系统的稳定性和可靠性.利用特制的K型铠装热电偶对声学高温计进行了标定,结果表明:声学高温计测温与热电偶测温相比,误差在2%以内;声学测温历史曲线与机组负荷历史曲线的变化趋势吻合,说明声学高温计可以完全取代炉膛烟温探针.

| Abstract: | In order to realize real-time monitoring of the flue gas temperature at the exit of the furnace,one-path acoustic pyrometer was developed based on previous work.It was installed for the first time on a boiler of certain domestic 300 MW power plant.After cold adjusting test,hot test and long time operation,the stability and reliability of the one-path acoustic temperature measuring system were verified.The acoustic pyrometer was calibrated by a special K-type armored thermocouple.Results show that the measur... |
