Converting Waste Agricultural Biomass into a Resource - UNEP

Larger woodchip storage systems require moving floors that move the
material to an auger placed at the end of the bunker.
4: Typical Moving Floor System
Wood pellets flow very easily and do not need special agitator systems. The
fuel is removed from the store by an auger, which lifts the fuel and deposits it
in a drop cell, which has three key functions:
It prevents air being drawn into the boiler
It measures the woodchips being fed onto the boiler stoker conveyor
It assists in preventing burn back from the boiler
The precise arrangements of the drop cell vary with individual suppliers. The
KSM unit is shown in Figure 5.
