Embodiment Construction

[0051] figure 1 An apparatus for applying a thermal treatment to a substance in a specific embodiment of the invention is shown, which is given the reference numeral 1 in its entirety.

[0052] In this example, the apparatus 1 is suitable for gasifying waste, such as vegetable matter waste or actually polymer waste, to produce synthesis gas, or actually methane gas or other dihydrogen gas.

[0053] Of course, this application is not limiting, and the device 1 can be used for many other applications. By way of example, mention may be made of heating, roasting, pyrolysis, gasification, devolatilization, drying, . . .

[0054] The device 1 has an enclosure 2 which extends substantially in a substantially horizontal direction and is kept at a distance from the ground by means of legs.

[0055] In this example, the substance is inserted into the capsule 2 in the form of a segmented solid. Fragmented solids can be in the form of powders, granules, chips, fibers, flakes, etc. and ...

Abstract

The invention relates to a device for the heat treatment of products, comprising:-an enclosure (2) having a shell made of a refractory material; -a screw (10) mounted in the housing for rotation about a geometric axis of rotation in order to move the product between the inlet of the housing and the outlet of the housing, the screw also forming a heating means for the heat treatment of the product by supplying power to the screw. According to the invention, the device comprises at least one heater element (17a, 17b) for heating the housing in operation, the heater element being arranged inside at least one wall of the housing. The invention also relates to a corresponding method.

Description

technical field [0001] The present invention relates to heat treatment equipment. [0002] The invention also relates to a method of applying heat treatment to a substance by means of such a device. Background technique [0003] The heat treatment equipment commonly used in the industry generally includes a transport member and a heater device that performs the heat treatment. [0004] In its patent EP 2 218 300, the applicant therefore proposes a thermal treatment plant comprising an enclosure and conveying means for conveying substances between the inlet of the enclosure and the outlet of the enclosure, the conveying means comprising a mounting To the inside of the enclosure a screw that rotates around the axis of rotation and means for driving the screw to rotate. The apparatus also includes heater means for heating the screw by the Joule effect. [0005] Substances for treatment are usually inserted in the form of dispersed solids at the inlet of the enclosure. The s...
