This unusual design feature a pneumatic or linear electric driven shaft operating vertically rising horizontal blade. Steel plant designers favor this construction for their very high reliability under exacting conditions of high temperature and dust load. Typical feature include quick acting pneumatic cylinder operation and an accumulator driven quick shut – off under pneumatic air supply failure condition. It incorporates a simplex leaf – seal arrangement for maintaining sticky flue gas particulates above their condensation temperature.
