声波法炉内冷态流场在线监测系统的应用

Application of the Acoustic Wave Method in In-furnace Cold-state Flow Field On-line Monitoring Systems

针对大型电站锅炉炉内流场在线可视化监测技术缺乏有效、便利的检测手段这一难题,研究基于声波测量技术进行了实验室冷态流场的试验。依据实验结果,将该技术成功应用于国电长源荆州热电有限公司1号锅炉和武汉钢电股份有限公司1号锅炉上。结果表明:研制的声波测量法用于锅炉炉内冷态流场的在线监测系统可以在四角切圆锅炉上广泛应用。

In the light of the untractable problems that the in-furnance flow field on-line visual monitoring technologies for large-sized utility boilers are short of effective and convenient testing means,the authors performed a cold-state model test in a laboratory of the method for measuring a flow field based on the acoustic waves.On this basis the test results,they successfully applied the technology under discussion in No.1 boiler in Guodian Changyuan Jingzhou Thermal Power Co.Ltd.and No.1 boiler in Wuhan Steel-power Stock Co.Ltd.It has been fourd that the acoustic wave method-based boiler in-furnace cold state flow field on-line monitoring system thus developed can be widely used in tangentially-fired boilers.
