Abstract
Abstract The invention relates to a method and apparatus for incinerating a railroad car in an incineration housing wherein the railroad car is ignited and a stream of air is delivered along the underside of the car while it is being burned. For railroad cars of the type having a center door opening, and as an alternative to, or in addition to, the stream of air on the underside of the car, air is blown into the interior of the car through the door opening during burning. The products of combustion produced during the burning are treated.
