A smoke control device for use in motor vehicle incineration. Smoke from burning vehicles in an incineration area is directed into a collecting chamber by controlled air flows and flaps. Updrafts evacuate the chamber and force the smoke into a combustion stack. The column of smoke in the stack is raised to combustion temperature by heaters mounted on the stack. The superheated smoke is combined with heated air in the vicinity of an open flame causing combustion resulting in a clear stack discharge.
