Abstract: A method of introducing a first flow and a second flow into a process liquid flowing through a conduit including: injecting the first flow with an introduction liquid into the process liquid in transverse to a flow direction of the process liquid, wherein the injected first flow forms a mixing field comprising counter-rotating vortices in the process liquid; and injecting a second flow transverse to the flow direction of the process liquid and between the counter-rotating vortices.

Abstract: Methods are provided for crystallizing a filler, especially in order to precipitate calcium carbonate on the surfaces of solids in the short circulation of a fiber web machine by feeding carbon dioxide and lime milk to the liquid flow of the short circulation and allowing them to react with one another, is characterized in that the feed system, the mixing method and/or mixing rate of the chemicals are selected such that a size distribution of the calcium carbonate crystals suitable for the purpose is obtained. Moreover, the invention relates to an approach system for a fiber web machine applying this method, characterized in that it is provided with devices for feeding and mixing carbon dioxide and lime milk into the liquid flow at such a rate that the applicable size distribution of the calcium carbonate crystals is obtained.

Abstract: The present Invention relates to a method of and apparatus for feeding a chemical into a liquid flow. The method and apparatus according to the invention are most preferably utilized for feeding a retention aid into fiber suspension flow going to the headbox of a paper machine so that in a mixing apparatus (34) feeding liquid is added into said retention chemical solution, prior to introducing said solution into the fiber suspension flow (70) guided to the paper machine, which feeding liquid is preferably some circulation water from the paper mill or some other non-clean liquid.

Abstract: A method of feeding chemical to a liquid in an open space or flowing in an open space so that the chemical is fed to the liquid by means of a special mixing device or several special mixing devices by means of feed liquid introduced to the mixing device separately from the chemical by allowing the chemical and the feed liquid to discharge essentially simultaneously through the nozzle opening of the mixing device, the opening being located under the liquid level in the space, to the liquid in the space or flowing in the space.
