Abstract
An additive injection apparatus has a flow manifold with an injection tube configured to communication an additive into the flow manifold. A hopper is connected to the injection tube and will deliver the additive to the injection tube. First and second valves movable between open and closed positions control the flow of additive from the hopper into the injection tube and from the injection tube into the flow manifold.
