Abstract
In a method for cleaning of flue gas derived from waste incineration, of the kind which comprises spray drying a lime slurry in the hot flue gas, the amount of active lime used is from 1.5 to 2.5 times larger than the amount reacting with the acidic components of the flue gas; furthermore, ground blast-furnace slag is incorporated in the lime slurry in an amount that is equivalent to 30 to 100% by weight of the amount of calcium salts generated at the flue gas cleaning. An end-product is hereby obtained, which upon admixing with water, forms a concrete-like material with high mechanical strength and great ability to retain the pollutants present therein so that the product is suited for disposal in nature with a minimum risk of polluting water streams and ground water.
