摘要: 为降低锅炉飞灰的含碳量,提高锅炉燃烧效率,基于频谱扫描、等质量取样、原位测量、同步取灰等技术原理,结合燃煤电厂飞灰收集设备的特点,研制了一种可用于静电除尘器的在线飞灰监测装置并应用于某电厂660 MW机组。以静电除尘器的飞灰为采样源,对该装置在不同负荷段进行了比对测试。测试结果表明,该装置的测量准确性系数为0.95,取样代表性系数为0.86,可用于考核锅炉燃烧效率。

Abstract: In order to lower the carbon contents in boiler fly ash and improve the boiler combustion efficiency, based on the techniques such as spectrum scanning, equivalent mass sampling, in-situ measurement and synchronous sampling and taking the characteristics of fly ash collecting equipments into account, a new online fly ash monitoring device is developed for the electrostatic precipitator and has been applied on the 660-MW unit of a power plant. By sampling the fly ash in the electrostatic precipitator, the comparative test on the device is carried out under different loadings. The test results show that the measurement accuracy coefficient of the device is 0.95 and the sampling representative coefficient is 0.86, which means that the device is ready to be used for the verification of the boiler combustion efficiency.
