Method for feeding bulk material into a space under overpressure, wherein the bulk material (20) is fed into a chamber (10) which is pressurized to a higher pressure, preferably corresponding substantially to said overpressure, and the material is fed into the space from the pressurized chamber. Simultaneously with or after the material being fed into the space, the volume of the chamber is reduced to a volume which is a fractional part of the normal volume of the chamber. |
