摘要
In a method for processing ash, fly ash is separated from a product gas flow obtained from gasification of fuel, which fly ash is burnt in fluidized bed combustion to reduce the carbon content in the ash, after which the flue gases from the combustion are processed. The ash is burnt by fluidized bed combustion at a temperature below 900°C for reducing the carbon content, and the flue gases produced by the combustion of ash are introduced into combustion air of a boiler (8) that burns the product gas obtained from the gasification.
