Biomass Boiler systems. Feed systems for your biomass boiler.
Fuelling by hand.
Pellets are stored in pre-packed bags
(normally 10-15kg) for ease of handling and
convenience. The bags can be purchased
individually or delivered on a pallet, making
them ideal for smaller domestic applications
and eco properties. Refueling commonly
takes place every one or two days.
Automatic vacuum transfer.
Pellets are stored remotely
in a large purpose designed
store or sack silo. Local to the
boiler is small pellet hopper.
When the pellet level of this
hopper drops below the preset
level, the system automatically
refills using vacuum transfer
from the main pellet bunker.
Used in larger properties where
pellets will be bulk delivered.
Automatic auger transfer.
Pellets are stored in a large bunker local to the boiler installation.
The pellets are auger fed directly from the bunker into
the boiler as energy is required. Normally
used in larger commercial
installations where pellet
quality cannot be
Wood chip feed systems.
Wood chip boilers employ delivery systems designed to transport wood chips,
wood shavings and wood pellets.
Wood chips are typically stored in a timber floored bunker. A flexi-blade agitating
head feeds the fuel into a central auger which then transports the material into
the boiler feed system. For large bunkers the blades are hinged for extra reach,
but otherwise work in the same way.
Wood chips are more bulky than pellets. Delivery in bulk is usual for wood chips
and provision to deposit them into the bunker by tipping and/or conveying is
designed into the installation. Key considerations are access for vehicles, proximity
to boiler and frequency and method of fuel delivery.
Wood chip delivery modules can be installed through 180 degrees left to right of
the boiler, which means they can be integrated into almost any location.
Feed systems for your biomass boiler.
Based on the layout of the building, size of the fuel store, boiler capacity and fuel type,
we offer custom tailored delivery systems, from spring steel blade and jointed arm
delivery to silo and walking floor delivery. HDG delivery systems are designed
to be robust and solid. Moreover, they offer a hassle-free means of quietly and
reliably supplying your system with fuel.
Spring steel blade delivery systems, transport and meter
fuel such as saw shavings, pellets and chips up to a size
of G50 (medium coarseness from 30 to 50 mm).
