Abstract
A method for the impregnation of untreated chips during the manufacture of chemical pulp. The untreated chips are fed without preceding steam treatment into an impregnation vessel that has an upper part with a first area (A) and a lower part with a second area (A) that is larger than the first area (A) by a factor of at least √{square root over (2)}. The chips establish in the upper part a level of chips that is located at a level (h) above a level of fluid consisting of liquor. The chips after passage of the upper part pass through a transitional part, where an increase in area from the first area (A) to the second area (A) takes place, and it is here that the angle of repose of the chips is reduced.
