Abstract

The invention concerns apparatus for the admixing of a first fluid, preferably steam, into the flow of a second fluid, preferably cellulose pulp. With the purpose of obtaining a high and good admixing capacity and avoiding the generation of noise, the admixing of the second fluid is effected in the end of a pipe, which pipe has an increase in area of at least 50 %, directly after the admixing, viewed in the direction of flow of the second fluid.
