Also called fly ash or soot. The fine ash in the flue gas generated by coal combustion generally refers to the fine ash collected from the flue gas in the coal fired power plant. It is formed after the pulverized coal enters the furnace at 1300-1500 ℃ and undergoes the endothermic cooling of the hot surface under the condition of suspended combustion.
