Features Biomass Boiler

Rendlesham Primary School is a new build school and opened in 2006.  As  part of Suffolk County Council’s Woodfuel programme, the school is heated using a 120kW Binder wood chip biomass boiler.  The equipment is installed in a  purpose built boiler and fuel store, providing an active storage area of 25m3.

The wood chip used in the boiler uses wood from the local Forestry Commission and is distributed by Eastern Woodfuel who are located less than 1 mile away from the school.  The wood chips are delivered by a specialist blowing vehicle which blows the fuel directly into the store.

Technical Specification 

  • 120kW underfed hearth Binder Boiler
  • 2000 litre buffer tank
  • Cyclone exhaust cleaner
  • Chip – blown in via specialist chip blowing vehicle
  • Expected fuel usage – 80-100 tonnes per year
  • Expected CO2 savings (compared with oil) – 75-90 tonnes/year

Biomass boilers that use locally grown wood chips for generating space heating and hot water, offer significant potential for carbon reductions, especially when they are used to replace oil-fired boilers, or even electric heating. Suffolk County Council has installed in the region of 4MW of biomass boiler capacity over the last 4 years encompassing  approximately 20 school sites. This overall capacity will deliver approximately 4440 MWh of renewable heat each year (enough to heat over 200 typical family homes) and will result in an annual carbon reduction in carbon emissions in the region of 1,600 tonnes.

Biomass installations to-date have been funded through  various bio-energy grant schemes however, moving forward future installations will be designed to be  eligible for annual renewable-heat payments under the Government’s renewable-heat-incentive (RHI) scheme.
