Abstract

PURPOSE: To maintain constant combustion conditions with the generation rates of NOx and hexavalent chrome reduced by making complete combustion while supplying preheating air to incomplete sewege sludge combustion product and dry sewege sludge gas and passing the product and gas through the refractory constructions in a furnace.
CONSTITUTION: Incomplete combustion product is supplied at a constant rate to a complete combustion furnace D through a transfer pipe 13, and dry sewege sludge gas at a constant rate to the furnace D through a transfer pipe 9. Combustion air is supplied to the furnace D by a blower 20. Refractory constructions 28 and 28' are provided in the furnace D. Supplied sewege sludge fuel is subjected to the complete combustion by the reflected heat from the constructions 28 and 28' in the atmosphere of about 800°C furnace-inside temperature, and the product thereof flows downward and is discharged through a discharge pipe 1 having a blower 17 provided in the bottom part of the furnace D.
