Apparatus for the burning of solids

Patent ·
OSTI ID:6723006
The patent concerns a system to burn waste materials with essentially complete combustion including a vertical preheating chamber with upper waste inlet and lower outlet, the outlet conducting preheated material into a furnace having a rotating frusto-conical grate with a vertix angle of between 90 degrees and 120 degrees arranged somewhat horizontal so a lowermost surface line is slightly inclined down toward the large inlet end of the grate relative to a horizontal reference. The furnace has an air inlet system which directs a controlled amount of combustion air to a specific limited zone of the grate. The grate, its disposition, and the air supply provide a waste material movement and burning to maximize effective use of combustion heat. The system also has apparatus for removing waste solids and gases from the furnace, with components to cool, wash and separate small solids from the waste gas and to utilize controlled quantities of the waste gas for introduction back into the inlet end of the preheating chamber.
