Title: Water cooling type incinerator
Inventor: ITAGAKI NOBUYUKI
IPC: F23M5/08
Filed: 1984-06-13
Abstract: PURPOSE:To facilitate discovery of any fault and repair of discovered fault so as to keep a satisfactory combustion condition by sloping the furnace floor and connecting a large number of blow-in tubes provided by penetrating through a water cooled jacket formed around the outer periphery of the furnace body to a blast tube at the outside of the furnace body. CONSTITUTION:Since the furnace floor has a downward inclination of 18-25 deg. from the charging port side toward the ash outlet side, remaining ashes burnt on the furnace floor flows down toward the ash outlet side naturally or by being pressed by matters to the incinerated which are newly charged. Hence, there is no need to stir them within the furnace during burning by a fire hook, and it is possible to burn them under a constantly excellent condition. Further, since a lot of blow-in tubes 6 penetrating through a water-cooled jacket 5 for forcibly blasting air into the furnace are connected to a blast tube 7 communicated with a blower at the outside of the furnace body, the outer side of the welded parts of the blow-in tubes 6 and the inner and outer walls of the water cooled jacket 5 can be observed from the outside of the furnace body, and the inner part thereof can be observed from the interior of the furnace body. Thus, generation of cracks or water leakage can be confirmed and further it becomes possible to easily repair them without breaking the furnace body.
