Abstract: Admixing of an atomized liquid to a gas flow (7 FIG. 1) may be performed without risk of recirculation and clogging caused thereby if the supply of atomized liquid according to the present invention is effected in separate part flows introduced into said gas flow (7) in such directions that each part flow has a component in the same direction as the direction of the gas flow (7). Each part flow is supplied at such location that it is wholly surrounded by a part of the gas flow (7). The invention also relates to a device for carrying out the above method, which device comprises a number of atomizing tubes for supply of the separate part flows of liquid and atomizing gas. The tubes have such axial and radial direction relative to the gas flow that the atomized liquid is directed into the gas flow to treat the gas flow in an area radially outside the tubes.
