Abstract
This invention discloses a method for reducing the yield of hollow glass microspheres from fly ash in coal-fired power plants, belonging to the technical field of hollow glass microspheres. One method involves selecting a type of pulverized coal as a reference, adding Al2O3 and SiO2 powders with a mass fraction of 0-40% to the reference pulverized coal, mixing them evenly, and then introducing the mixture into the furnace for combustion. After cooling, hollow glass microspheres are generated. This invention allows for flexible control of the hollow glass microsphere yield according to the actual conditions of the power plant, maximizing ecological and economic benefits. By selecting different coal types, blending coals, or adding additives to control the yield, no power plant modifications are required, and the operation is simple and easy to implement.
