INCINERATOR FOR BURNING COMBUSTIBLE REFUSE

摘要

An incinerator for burning combustible refuse which comprises: a horizontally disposed stationary cylindrical combustion chamber means having an inlet end for receiving refuse and an outlet end for discharging residue and exhaust gases; ignition means adjacent the inlet end for igniting the refuse; screw conveyor means extending through the length of the chamber means for moving refuse at a decreasing rate from the inlet end to the outlet end of the chamber means as the volume of refuse is reduced by combustion, to effect better combustion of particulate smoke at the outlet end of the chamber means, the screw conveyor means including a rotatable auger having a longitudinal axis and a spiral flight having a larger pitch at the inlet end of the chamber means and a smaller pitch at the outlet end of the chamber means; and air supply means for supplying combustion air to said chamber means.
