Abstract: A fly ash recycling gasification furnace includes a fly ash burner, an ash remover, a fly ash storage tank, a variable pressure lock hopper, a fly ash blending system, an exhaust filter, and a backflushing nitrogen buffer tank. The fly ash burner is located on an inner wall of a hearth of the gasification furnace. The ash remover has an inlet connected to an outlet of a waste boiler of the gasification furnace. The fly ash storage tank is connected to a pressurized nitrogen inlet pipe, and a bottom outlet of the ash remover. The variable pressure lock hopper is connected to the fly ash storage tank. The fly ash blending system is connected to the variable pressure lock hopper and the fly ash burner. The exhaust filter is connected to the storage tank, the lock hopper and the blending system. The buffer tank is connected to the exhaust filter.

Abstract: A hollow spherical cerium dioxide nanomaterial, preparation method and application thereof; wherein the preparation method uses glucose as a carbon source, urea as a precipitant, cerium trichloride as a cerium source, and water as a solvent to prepare a cerium dioxide/carbon composite material by a hydrothermal method, and then, a hollow spherical cerium dioxide nanomaterial with a multi-shell layer structure is obtained by calcination in a muffle furnace. By adjusting the amount of urea and the calcination temperature, a number of shell layers of the material can be adjusted. Moreover, in the nanomaterial, the number of shell layers can be adjusted, large spacing exists between shell layers, specific surface area can be increased, wherein contact area of the material with an electrolyte increases, but also structural collapse caused by a volume expansion of an electrode material during charging and discharging can be alleviated, and the electrochemical performance is effectively improved.
