The work is devoted to the determination of the content of carbon underburn and iron in the fly ash of thermal power plants. The results of determining the mechanical underburning by fractions for three stations are presented to show that the stations have a slight underburning besides the Tom-Usinsk SDPP. In addition, there is a general regularity showing a 4-10 times higher content of remnant carbon in fly ash than in slag. Data are presented on the composition of elements of sulfur, calcium and iron in the original fly ash and in the separated magnetic fraction in a one-step separation on a magnetic analyzer in water.
