A full documentation set to turn fuel tanks into pellet storage units for feeding biomass boilers. Product includes technical description, schemes and instruction manual for installers to retrofit existing tanks into pellets tanks successfully.

The solution consists to recover tanks that contain liquid fuel in order to store solid material following this procedure: retrofitting, adapting, transforming and mechanizing an existing tank to store a new fuel type such as biomass.

Subsequently, the conversion consists in adapting the tank so that it can be filled through a direct off-load discharge or through a tanker pneumatic system. The extraction of the solid fuel to supply a boiler is carried out by a suction system.
