Biomass Boiler Systems
Biomass Boilers are very environmentally
friendly: they burn wood pellets made from
compressed waste sawdust or from raw
materials sourced from sustainably managed
forests in the UK. The sawdust is a waste
product from sawmills and classed as a
renewable, carbon neutral fuel source because
trees absorb as much CO2 when they are
growing as they emit when they burn.
Biomass Pellets
Pellets are made from a wood material which
is dried and compressed to a low moisture
level with no additives. The resulting fuel has a
high calorific value or heat content and is
clean, burning easily and efficiently to give a
constant heat. Biomass boilers differ from
solid fuel boilers as they are fully automatic,
using advanced controls to regulate the
amount of fuel being delivered to the boiler to match the heat demand. The process produces ash,
so most Biomass boilers require regular cleaning and maintenance, however the boilers installed by
DalesRenewables are self-cleaning and only need a manual clean once a year.
When the boiler is started, the auger feeds the pellets from the hopper into the burner where it is lit
by an ignition element. The burner controls the feed rate of the pellets to achieve the required set
temperature. The fan within the boiler then propels the hot gas into the primary heat exchanger.
The resulting heat energy is transferred to the water for the central heating
system and this is finally circulated around the house.
About Biomass Boilers
The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and
industrial residues and waste to produce heat and electricity with less effect on the environment than
fossil fuels. This type of energy production has a limited long term effect on the environment because
the carbon in biomass is part of the natural carbon cycle; while the carbon in fossil fuels is not, and
permanently adds carbon to the environment when burned for fuel. About Emissions.
