Definitions

the heating element being arranged inside one or more walls of the envelope, it is thus protected from the atmosphere present inside the envelope due to the heat treatment of the product; atmosphere that could potentially be corrosive depending on the product to be treated.
the heating element is arranged at the entrance to the envelope.
At least one heating element is arranged so as to extend at least in one of the lateral sides of the envelope.
the heating element extends over between 75 and 95% of the height of the envelope.
the device comprises a chimney connected on the one hand to the inlet of the envelope and on the other hand to an air inlet for the introduction of a controlled air flow into the enclosure.
the enclosure 2 further comprises at least one first outlet 6 arranged here in the bottom of the enclosure 2 substantially at the level of the second of the two longitudinal ends of the enclosure 2.
the device 1 comprises an outlet chimney 9 which is connected in a sealed manner to the second outlet 8 of the enclosure 2.
the outlet chimney 9 is for example connected to a device for post-processing the gaseous by-products for example to purify said gaseous by-products.
Enclosure 2 here has a rectangular section.
the enclosure 2 is for example made of metallic material.
the device comprises an envelope 11 of refractory material which is arranged in the enclosure.
the screw 10 extends directly inside this envelope 11 which is itself arranged inside the enclosure 2. More precisely here the screw 10 rests on a bottom 12 of the envelope 11.
a first pair of heating elements 17a, 17b is arranged at the very beginning of the envelope 11 upstream of the inlet 4 of the envelope 11.
a second pair of heating elements 17a, 17b (not visible here) is located at entrance 4, on either side of it. The rest of the pairs of heating elements 17a, 17b are arranged subsequently.
Each heating element here is a heating cartridge.
Each heating element therefore has a tubular shape with a square, round, rectangular section, etc.
the device 1 comprises a second control unit 25 of the heating elements 17a, 17b which controls at least the electrical power delivered to the heating elements 17a, 17b as a function of the data transmitted by at least the second measuring member 23.
the second control unit 25 is for example a calculator, a computer, a microprocessor, etc.
the screw may be different from what was noted.
the screw may present a resistance which varies along the geometric axis of the screw as proposed in the patent FR 2 995 986 of the present plaintiff.
the product is introduced in the form of solids divided into the enclosure
the product could be introduced in another form, for example liquid or even gaseous.
one or more products can be recovered at the output in the form of gas, liquid, oil, solid, etc.
the number of inlets and outlets from the enclosure will vary accordingly.
