The carbon content of fly ash produced by power plants is the most representative.

Generally, fly ash sampling is divided into three places: flue, dust collector and ash storage yard.

In order to accurately consider the comprehensive utilization of ash, ash storage yard is generally more accurate.

If it is only calculated as a small index and used as the basis for operation adjustment, take the flue as an example.

Due to the different installation positions and sampling devices, the flue is the smallest and the ash storage is the most accurate. If it is electrostatic precipitation, the electric field is the smallest, and the larger it is in turn.

I hope it helps you.
