Separator for separating solid particles from a vapour-gas mixture

The present invention is related to the separator for separating solid particles from a vapour-gas mixture, and particularly to the structure of a dust chamber (2) as installed in the plant for processing fossil fuels or materials containing organic matter. The dust chamber (2) comprises a main body (4) having an inlet (14) for a vapour-gas mixture containing semi-coke particles and an outlet chute (9) for removal of semi-coke particles, wherein the upper part of the main body (4) is connected to the inlet of a cyclone (3) for removal of fine semi-coke particles from the vapour-gas mixture and wherein a screw conveyor unit (13) is connected to the bottom part of the main body (4). Said main body (4) is covered with an external insulation (5). Electrical trace heating cables (7) are in contact with the external surface of the main body (4) of the dust chamber (2).
