Abstract

An injection device for humidifying a reactor space and injecting and dispersing reagents into the humidified reactor space, including an exterior injection duct for high-velocity gas injection and at least one interior injector for reagent and humidifying agent injection as droplets with a droplet environment. The high-velocity gas ensuring the humidification of the liquid droplet environment and mixing and dispersion of the liquid reagent droplets into the reactor. A multiple injection device system and a method for operating the system are also described.
