<p>A method for feeding a chips slurry from a low- to a high-pressure system during the continuous cooking of chemical cellulose pulp. The feed takes place through a sluice feeder (53') between these systems. The sluice feeder is provided with a rotor with through-pockets (1, 2) that are alternately connected with the low- or the high-pressure system. A recirculation line (54') comprising a high-pressure pump (57') extends from the first outlet (53b') of the sluice feeder to the second inlet (53c') of the sluice feeder for transport of the fluid that has been expelled from the pockets of the sluice feeder when these are located in their first position. The fluid that according to the method expels the chips mixture from the pockets of the sluice feeder in their second position is essentially exclusively constituted by the fluid that has been expelled from the pockets in their first position.</p> |
