INCLINED ROTARY GASIFIER WASTE TO ENERGY SYSTEM

A gasifier system includes a reactor for receiving a wet feedstock which has a base and a container rotatably connected to the base such that a rotation of the container causes a mixing of the feedstock in an interior of the reactor. The interior is bounded by the base and the container. A space between the base and the container allows an entry of oxygen into the interior. The space has a dimension such that the feedstock is fully oxidized in a combustion area adjacent the base and such that the feedstock avoids combustion in a remainder of the interior. The reactor has a longitudinal axis inclined at an inclination angle relative to a horizontal line to promote the mixing of the feedstock in the interior.
