Abstract: A dispersion lance is for use in combination with a fluid treatment system of the type which includes a flow duct in which a fluid stream is mixed with a treating agent. The dispersion lance includes a pipe mounted in the duct with its axis approximately transverse to the direction of the fluid stream flow, the pipe having a series of openings along its length for injecting a treating agent into the fluid stream. A baffle extends lengthwise along the pipe, the baffle having a cross-section the central portion of which is V-shaped, with the apex of the V facing upstream of the fluid stream flow, and with generally flattened wing portions extending from the legs of the V beyond the sides of the pipe in a direction where they transversely intersect the stream flow. The baffle acts to generate a low pressure zone on its downstream side which enhances turbulence in the fluid.
