Abstract
PURPOSE: To make fugacious salts contained in the electrically collected ash and condense the vapors on packed layers by a method wherein packed layers of granular refractory material are provided in a fractionating tower at an upper part of a meltin furnace, the packed layers are maintained at temperatures such that the temperature is gradually lowered in the direction from the lower layers to the upper layers, and the electrcally collected ash is melted in the furnace.
CONSTITUTION: Granules of a basic or neutral refractory material are packed in the fractionating tower 2 at the upper part of the melting furnace 1 to form the packed layers 3. The packed layers 3 are maintained in a predetermined temperature range in such a manner that the temperature is gradually lowered from the lower layers to the upper layers, by respective heating elements 9. In this condition, when the electrically collected ash 10 is placed in the melting furnace 1 and is melted, salts contained in the ash are made fugacious and the vapors are condensed on the packed layers 3. Thus, the electrically collected ash is melted, noxious heavy metals contained in the ash are evaporated or they are dissolved into a vitreous or crystalline structure formed by solidiying a molten slag, thereby preventing the elution of the heavy metals.
