Abstract
The invention relates to an injection probe, particularly for the sulfur trioxide conditioning of flue gasses, comprising a tubular, closed-end outer casing, a manifold connected to a feed conduit and provided with radially projecting injector tubes, the ends of which project through openings in the outer casing, being disposed within the casing and at least partially surrounded by an insulating material, and a mounting flange connected to the outer casing for attachment of the injection probe. In a known injection probe of this type, employed for injecting sulfur trioxide at a high temperature into a flue gas stream having a lower temperature, there occur considerable heat losses between the supply inlet end of the injection probe and the ends of the injector tubes, resulting in damage to the injection probe, undesirable sedimentation and unsatisfactory operation. In accordance with the invention, the heat losses can be avoided by reducing the surface of the outlet opening of each injector tube exposed at the outer periphery of the outer casing with respect to the cross-sectional area of the injector tube.
