Abstract
PURPOSE: To increase the incinerating ratio of EP ashes and to economize the cost of fuel remarkably by a method wherein a fluidized bed furnace is provided in a dry box part of the bottom of a boiler.
CONSTITUTION: A porous plate 35 is arranged in the dry box 23a hanged from a lower cone 20' of a boiler body 20. A duct 38 for supplying combustion air A joins a recyclic duct 26 of combustible gas to make a fluidized gas supply duct 37 and to connect with a wind box 36. The EP ashes are supplied from an EP ashes nozzle 29 to the fluidized bed part. The inner part of a fire chamber 21 is 1,000W1,200°C in temperature and the recyclic exhaust gas is about 300W 350°C. Accordingly, the temperature of the fluidized bed 34 ranges 500 and 800°C by means of the heat due to combustion of EP ashes in the bed and the radiant heat of the fire chamber 21. Therefore, metals contained in the EP ashes are hardly softened, most of ammonium sulfide is decomposed in the fluidized bed and the EP ashes burn well.
