1. A stationary material mixing apparatus located within a cylindrically-shaped conduit, said conduit having upstream and downstream ends, a circular cross-section and longitudinal axis located along its geometric center, said material mixing apparatus providing for mixing an additive into a fluid stream moving from said upstream end to said downstream end within said conduit, said material mixing apparatus comprising a front face facing said upstream end and a rear face facing said downstream end and a circular periphery sized to occupy substantially the entire cross-section of said conduit, said front and rear faces of said material mixing apparatus having a geometric center, a cone-shaped module having a base and apex, said base being supported by said front face at said geometric center, said apex extending toward the upstream end of said conduit, a channel for introducing an additive to said fluid stream, said cone-shaped module being in fluid communication with said channel for passage of said additive from the apex of said cone-shaped module into said fluid stream, said stationary material mixing apparatus further comprising three circular openings configured therein for passage of said fluid stream within said conduit, said circular openings being equidistant from said geometric center spaced approximately 120 degrees from each other and each opening being fitted with a baffle, a first edge thereof being curved to mate with a circular opening to which it is fitted and a second edge, said second edge being spaced further away from said longitudinal axis than said first edge, said baffle being angled away from said front face of said mixing apparatus. |
