ABSTRACT:
Swirl nozzles, especially for plants with flue gas scrubbers for the physical and/or chemical purification of flue gases emanating from power plant boiler installations. The nozzles include a substantially cylindrical nozzle chamber, at least one tangential scrubber fluid inlet into the nozzle chamber, and at least one nozzle bore arranged in a nozzle chamber bottom and extending coaxially with its axis with respect to the nozzle chamber. A conduit for feeding scrubber fluid can be secured at the tangential scrubber fluid inlet, and this conduit carries the swirl nozzle apparatus. The nozzle chamber and the inlet are provided in a body made of ceramic wear material, with the respective ends of the chamber also made of ceramic wear material and connected to the body. At least one chamber bottom includes the nozzle bore. The body and the nozzle chamber bottoms are arranged between steel stress plates. At least the body can be held under pretension condition between these stress plates. One of the stress plates includes an aperture at which can follow the scrubber fluid inlet, and it is also equipped with a short connecting pipe for the conduit for feeding a scrubber fluid.
