A method for high temperature purification of flue gas for incineration plant for household waste (Process for Hot Dedusting of Combustion Gases, Particularly for Household Refuse Incineration Plant)

摘要

The method involves circulating the combustion gas through a filter (4) disposed in a heat recovery boiler (3a, 3b) for hot filtration of the flow of fly ash contained in the gas. Another flow of material (b) is added to the flow of fly ash to be filtered, which is formed by molding of a high melt mixture to facilitate removal by avoiding the formation of a viscous bridge between the particles of fly ash, The temperature of the molten metal increases. The present invention is applicable to high-temperature dust removal of waste gas from the combustion of household waste.
