A stationary material mixing apparatus for mixing various components in a fluid stream. The mixing apparatus is in the form of a cone-shaped module containing a plurality of openings therethrough where within the openings are located mixing elements which induce a rotational angular velocity to the fluid stream. As preferred embodiments, the mixing apparatus, located within a conduit, can also contain a biscuit with further mixing elements and a series of either helically wound tubes or vanes further enhancing the mixing operation.

[ I claim:] [1.] A stationary material mixing apparatus located within a cylindrically-shaped conduit, said conduit having an upstream end and a downstream end and a circular cross section and longitudinal axis located along its geometric center, said material mixing apparatus provided for mixing an additive into a fluid stream moving from said upstream to said downstream ends within the conduit, said mixing apparatus comprising a cone-shaped module with its apex pointing toward the upstream end of the conduit and having a series of openings emanating from the side wall of the cone to its base for the passage of said fluid stream therethrough, each opening being provided with a mixing element which induces a rotational angular velocity to the fluid stream passing therethrough, an additive feed line located downstream of said material mixing apparatus for introducing additive through said cone and emanating from said cone upstream of said series of openings so that said additive and said fluid stream are caused to together pass through said series of openings for mixing.
