FIELD: machine building.
SUBSTANCE: chamber consists of working part of pass-through type for input and output of material, of directing shafts, of facilities for supply of oxidant and gas medium and for removal of pyrolysis product. Also, chamber consists of heating elements. The working part consists of successively connected sections in form of pressure tight interconnected central, inlet and outlet module sections with channels. Inlet and outlet module sections are pressure tight attached with their ends to inlet and outlet sluice boxes; a lower section is pressure tight isolated, while channels of the sections, except the second one from below, are closed on ends with gas gates.
EFFECT: intensification of treatment process, increased uniformity of fibres characteristics, safety and reduced power expenditures.
