ABSTRACT:
An apparatus for discharging to the atmosphere, combustion gases containing sulphur trioxide, means are provided for injecting into the stream, prior to venting to the atmosphere, a selected quantity of diluting gas. The diluting gas and sulphur containing combustion gases are turbulently mixed to provide dilution of the sulphur trioxide in the combined effluent from the stack. In one embodiment, the diluting gases are injected through a pipe positioned axially in the stack, below the top. A column of diluting gas is injected at high velocity into the upwardly moving combustion gases to entrain, mix with, and dilute the sulphur trioxide in the combination gases prior to escape from the stack to the atmosphere. In an improved embodiment, an annular plenum is constructed around the stack at a point upstream of the top of the stack, and a plurality of pipes are directed inwardly radially and upwardly through the wall of the stack. Diluting gas is supplied to the plenum at substantial pressure, which flows through the pipes at considerable velocity into the rising column of combustion gases.
