Abstract (en)
A mixture of air and liquid is introduced to a premixer (12) comprising a cylindrical casing housing a plurality of convoluted elements arranged end-to-end along the longitudinal axis of the casing. The air/liquid blend exiting the premixer is introduced to a static foamer (14) which is identical to the premixer except that it additionally contains a porous bed of spherical beads which fill the space between the convoluted elements and the casing.
