ABSTRACT:
A rectangular microwave applicator for processing waste material. The rectangular microwave applicator generally includes an upper cavity and a waste container. The upper cavity defines side walls and a ceiling, the bottom of the upper cavity is open. A screwfeeder tube is positioned on and extends through one of the side walls, and a vent is positioned on and extends through another of the side walls. The waste container is rectangular in configuration and is receivable in the bottom of the upper cavity. The waste container holds waste material which is introduced therein via the screwfeeder tube. A microwave choke is carried across the bottom of the upper cavity and is configured to permit the entrance of the waste container in the bottom of the upper cavity. A microwave energy input is at each corner on top of the ceiling of upper cavity and extends therethrough. Each of the corner microwave energy inputs delivers microwave energy to waste material in the corners of the waste container and is configured to transform a rectangular waveguide to a circular waveguide to maintain microwave energy in the corners of the waste container for effective heating of the waste material.
