Two independently controllable worms are arranged in a worm conveyor tube (6). The biomass is compressed by high pressure, between the primary worm driven by the motor (12) and the secondary worm driven by the motor (11), as a result of different rotational speeds of the motors (11, 12), in such a way that an almost gas-tight plug (13) is formed. The invention is suitable especially for introducing biomass into a pressurised gasification installation for producing synthesis gas. |
