This invention relates to a process for injection of fluid e.g. slurry into e.g. flue gases, and a nozzle device for the accomplishment of the process. The process according to the invention is characterized in that a thin stream of fluid e.g. slurry is injected into a wider stream of gas to form disintegrated drops, at which the fluid stream is peeled off on its way into the gas stream, the fluid stream is made to turn 180 DEG and accelerate against a solid body, where another disintegration of the drops occurs very rapid and the nozzle device according to the invention is characterized in that it (4) is arranged with two intakes (2 and 3) coming into the nozzle opposite to each other, perpendicular to the passage of the flue gas through a flue gas pipe (1) at which slurry is injected through the intake (2), which is formed as a wider pipe (2), which ends in a wearing part (5), in which a finer pipe (2') is arranged and at which compressed air or steam is injected through the intake (3) arranged as a pipe (3'), besides which the finer pipe (2') for slurry is centered in relation to the pipe (3') so that a thin stream of slurry is arranged to be injected at a high speed into a wider stream of compressed air or steam to form fine slurry drops, which are arranged to be spread by the flue gas through the nozzle device.
