Lint burning clothes dryer

A clothes dryer having a cylndrical lint screen connected to and extending from the rear of a rotating clothes drum having a perforated front annulus and a rear air inlet. An air duct has a mouth at one end positioned adjacent to the perforated annulus and a blower is connected to the opposite end. The blower creates an induced draft on a burner located adjacent to a portion of the lint screen by drawing air from the burner into the drum air inlet and out the perforated annulus into the duct. From the blower, the air is forced into a plenum which is separated into two compartments by the rotating lint screen filter. In passing from one compartment through the lint screen filter to the other compartment from which it is exhausted, airborne lint in the air is collected on the lint screen filter. Rotation of the lint screen filter moves the lint into the flames of the burner where the lint is incinerated.
