<p>PURPOSE:To provide a method and an apparatus for fluidized bed refuse burning in a fluidized bed refuse burning furnace in which there is reduced an influence of harmful gas such as hydrogen chloride in a heat exchanger part, etc. CONSTITUTION:There are provided processes of (a) a drying/thermal decomposition process in which refuse is dried and thermally decomposed with hot air in a drying furnace 12 and is separated to unburnt gas containing water vapor and hydrogen chloride and unburnt solid, (b) an unburnt solid burning process in which the unburnt solid is introduced into a fluidized bed burning furnace 16 and a desalting agent is supplied to a fluidized bed 18 for burning, and (c) an unburnt gas burning/desalting process in which unbburnt gas containing water vapor and hydrogen chloride is introduced into the fluidized bed burning furnace 16 and is burned, and the hydrogen chloride and a desalting agent contained in waste gas are brought into a reaction for desalting.</p> |
