The invention relates to a power station boiler fly ash on-line sampling monitoring system. The system comprises a fly ash sampling and conveying device, a fly ash sample carbon content analysis device and a sample collecting and discharging device; the upper stream of the fly ash sampling and conveying device is connected with an ash bucket below a tail flue; the lower stream of the fly ash sampling and conveying device is connected with the fly ash sample carbon content analysis device; the lower stream of the fly ash sample carbon content analysis device is connected with the sample collecting and discharging device; and the lower stream of the sample collecting and discharging device is connected with a fly ash conveying pipeline. Compared with the prior art, the system avoids the problem of system blockage in an operation process and enhances the representativeness of samples collected by a fly ash sampling system. With a non-sampling type fly ash detection system adopted, the hysteresis quality of a sam
