Steam and Hot-Water Space Heating Boilers:Gas-Fired …

Coal-burning boilers may be hand-fired or fitted for automatic stoker operation. In many automatic stokers, fuel is carried from the hopper through a feed tube by means of a rotating worm. Intermittent action of the worm agitates the fuel bed, prevents arch- ing of the coal in the retort, and ensures that the incoming air reaches every part of the fire at all times.
