Storage

Innovation in biomass condensation

The choice of suitable fuel storage will depend on your energy needs, usable space and supply availability near the facility.

In a first approximation, from 25 to 30 kg of wood pellet are required annually per square meter of surface to be heated. This consumption may be vary dramatically depending on – among other factors – the boiler efficiency, the type of heating emitters, the local climatology, the building energy rating or the fuel heating value.

If the pellet chosen has good quality, the boiler is efficient (higher than 95%) and the facility is isolated, this consumption may be noticeably reduced.

Once the annual fuel requirement has been determined, it is advisable to verify its availability nearby, and the type of supply: 15 kg bags (available today in a wide variety of shops such as service stations or DIY warehouses), or, if the volume is considerable, in big-bags or pellet tankers.

The BioCurve BCH boiler guarantee is valid, among other conditions, by using only ENplus A1 accredited pellet. In this link you can find your nearest ENplus pellet manufacturer or distributor.

It is convenient to know as well that the density of the pellet in bulk is approximately 650 kg per cubic meter.

These data will be helpful to properly size the silo, being aware that it can be recharged several times a year if necessary. For optimal management, it should have the capacity to house at least 4-5 tons of pellet (about 6-8 cubic meters), to be periodically filled from tank truck.

If the available room is enough, a silo capable of holding the annual consumption will allow the end user to negotiate better supply conditions in the off-season.

Always keep in mind local current regulations, to verify the legal storage requirements, such as fire resistant walls.

Textile silos for feeding wood pellet by auger

  • The BioCurve silos, although they allow the passage of air, are waterproof and impermeable to dust, so under normal conditions, the pellet will be in perfect condition.
  • They come equipped of factory with the Storz connector for its filling from truck, and with a sleeve of security for its manual filling by sacks.
  • Feeding the boiler by an auger is a silent and reliable system, with great ease of dosing. It is ideal for dwellings and small spaces, where the distance between boiler and silo is not larger than two meters. Their assembly is fast, they have factory guarantee and extraordinary robustness.
  • If the consumption is low, and the usual filling of pellets is done by bags, you can choose a mini manual loading silo, which includes as standard the auger feeding the boiler.

Textile silos for feeding wood pellet by pneumatic system

  • If the geometry of the facility makes difficult the silo placement next to your BCH, a good alternative enables to place the silo away from the boiler (up to 20 meters, depending on the conditions of the feeding circuit).
  • The transport of the pellet between the silo and the boiler will be carried out by means of an automatic suction system integrated in the boiler.

Construction silos

  • It is likely that the space available is very unique, or the fuel volume to be stored considerable.
  • We then have the option of enabling a room as a storage silo.
  • The silo filling will be done through Storz fittings. These must be located on the wall that enables the easiest access for the tanker. Close to the opposing wall a rubber screen will be placed to absorb the pellet impact and minimize any damage.
  • It is advisable to cover the walls of the masonry silo with a material that can absorb the humidity, such as wood planks.
  • The collection of the pellet from the silo and its subsequent feeding to the boiler, will be made through pneumatic, auger systems or a combination of both.
