Fig. 71.—Showing the feed cylinder tilted forward and filled withcoal. The apron closes the opening in the center of the grate throughwhich the coal is forced upward into the fire box. In the underfeed furnace, fresh coal is introduced at thebottom of the fire bed. Distillation of the volatile mattertakes place therefore at the bottom of the fire, where theoxygen supply may be more abundant than on top of the
