Abstract

The invention concerns a method of feeding bulk materials such as wood chips, sawdust or wood fibres into a stream of gas or vapour at high pressure, in particular a pressure higher than 15 bar, and moving at a high speed, using in particular a worm conveyor. The material is fed in at a constriction in the flow cross-section at which the static flow pressure is considerably reduced compared with the mean static pressure. This method is suitable for use in the treatment of lignocellulose-containing material by hot steam.
