Vitrification of municipal solid waste incineration fly ash: An approach to find the successful batch compositions

摘要: Abstract Incineration is the most common way to reduce mass and volume of municipal solid wastes. One dangerous by-products incineration process fly ash that contains a considerable amount heavy metals. Therefore, its treatment crucial prevent leaching metals into environment. In present work, two different sources waste incinerator have been vitrified in order inhibit release potentially toxic Two silica, i.e. silica sand glass cullet, added each type an attempt obtain vitrifiable batches. The standard test on products was performed according EN12457-2 confirming no metal and, therefore, they all pass acceptance criteria be classified as inert material. Furthermore, previously reported data for vitrification combined with work their compositions were presented SiO2–Al2O3–CaO, SiO2-ΣM2O3-Σ(MO + M2O) ternary phase diagrams identify region which successful are concentrated. This analysis could facilitate find right composition ash.
