摘要: An evaporation apparatus for evaporation of, for example, spent liquor from pulp cooking. The apparatus has a vertical cylinder that has evaporation surfaces disposed therein. An outlet opening is defined in a widened part of the cylinder to receive driven-off steam. A skirt is disposed in the cylinder and surrounds the evaporated liquid and driven-off steam and has a diameter that is smaller than a diameter of the widened part. The skirt has an open bottom and a skirt opening is defined in a portion of the skirt that is facing away from the outlet opening.
