doi:10.11930/j.issn.1004-9649.201802086

Abstract

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.

Key words: coal-fired power plant, carbon content in fly ash, electrostatic precipitator, spectrum scanning
