Abstract

PURPOSE: To obtain an incinerator provided with a primary combustion chamber, a secondary combustion chamber and an annular heat-exchanger circuit so that the unfavorable influence of ununiformed supply if any may be eliminated, the genera- tion of NOx and hexavalent chrome and fuel consumption may be minimized.
CONSTITUTION: The sewege sludge in a hopper A is supplied to a drying oven B with fluidic sand bed by a supply means 1. While transferred by a transfer pipe 9, part of sewege sludge product is distributed to a primary combustion chamber C and a secondary combustion chamber D, and the remainder is heated after passing through a heat exchanger E and returned to a drying oven B. Water sludge makes imcomplete combustion while dried in the chamber C first and complete combustion in the chamber D next. Complete combustion gas is discharged after heating water sludge gas during the drying thereof in the heat-exchanger E.
