ABSTRACT:
A retort oven for decomposition of waste materials through pyrolysis employing a deck with a variable angle of inclination for adjusting the retention time and processing rate of waste material flowing unassisted through the oven interior. The oven includes an outer shell lined with a refractory material and houses an inner oven chamber. The deck is adjustably hinge mounted to the inner chamber supporting sidewalls extending in a decline from a waste material entrance to a charred material exit. The deck is operated in a preferred angle range of inclination between 28°-50° from the oven floor normal. A controlled heat source is positioned within the oven to heat a first outer volume whose heated gases are transferred into a second inner volume of the inner chamber using an array of heat gun tubes heating the deck and material as it descends along the declined deck. The deck can be adjusted for varying the retention time of material within the oven for varied exposure to heat and charring efficiency.
