Drag-chain conveyor of the pull bar storage

When the need for fuel is great (heating plants for industrial use and population centres), wood chips are fed by using a drag-chain conveyor. The notably greater feed capacity than that of the screw conveyor ensures that there is a sufficient amount of fuel for producing the heat required in all circumstances.
