Patent number: 12048956Abstract: A method of recovering fly ash, including a firing step in which raw fly ash powder containing unburned carbon is fired to remove the unburned carbon by burning; measuring the content of unburned carbon in the raw fly ash powder; and obtaining a fine fly ash powder which is a component under a sieve and has a decreased content of unburned carbon as a result of sieve-classifying the raw fly ash powder. The perforation size of the sieve used in the sieve-classifying step is set depending upon the content of unburned carbon in the raw fly ash powder. The sieve has a small perforation size when the content of unburned carbon is large, and the sieve has a large perforation size when the content of unburned carbon is small. The fine fly ash powder, which is the component under the sieve, is recovered through the firing step.Type: GrantFiled: June 4, 2019Date of Patent: July 30, 2024Assignee: TOKUYAMA CORPORATIONInventors: Kohei Omura, Takuya Seki
