Abstract
An air damper assembly for a coal-fired furnace in which a damper sleeve extends between two spaced walls adjacent the furnace in a manner to define an air inlet. A threaded support member is connected to the damper, and a threaded shaft is in threaded engagement with the support member. Rotation of the shaft causes corresponding movement of the support member, and therefore the damper, to vary the size of the opening and therefore the amount of air introduced into the furnace.
