Patent ID: 7448332

Claim:
The method of disintegration of non-radioactive refuse for reducing air pollution and for producing recoverable energy comprising the steps of: (a) providing a rotating cylindrical kiln as the primary refuse combustion chamber; (b) feeding compressed solid refuse into said rotating kiln; (c) initially igniting said refuse in said primary combustion chamber with an auxiliary fuel burner to initiate combustion; (d) selecting a rotation rate of said kiln to achieve a desired angle of repose for the refuse during combustion; (e1) providing an air inlet pipe into said rotating kiln along the center of the longitudinal axis of said cylindrical kiln; (e2) providing an exhaust gas flow leaving said kiln into an afterburner resulting in a lower internal air pressure in said kiln below ambient pressure and drawing in said air in said air inlet pipe into said primary combustion chamber; (e3) adjusting the oxygen input into said air inlet pipe to a level to sustain combustion of said refuse at about 1900 degrees Fahrenheit; (f) burning the exhaust gases from said primary combustion chamber in said afterburner at about 1700 degrees Fahrenheit; (f1) providing a fan downstream of said afterburner for drawing gases out of said afterburner; (g) controlling the oxygen in said afterburner with an air inlet valve into said afterburner that also controls exhaust flow gases from said primary combustion chamber; (h) moving said exhaust gases from said afterburner into a cyclonic separator; (i) separating ash particulates from gases in said cyclonic separator; (j) removing said gases from cyclonic separator using said downstream fan; (k) passing said exhaust gases through a heat exchanger to remove heat from said exhaust gases; (l) providing an air control system including a filter to separate ash particulates and remove them from said exhaust gases; (m) mounting said fan downstream of said air quality control system; and (n) using said fan discharging said finally filtered gases into a gas discharge stack for discharge into the ambient air.
