- We reduced the annual grain drying cost for one farm business from approximately £40,000 in an annual season to less than £6,000 in the first season. Taking into account the award from the Scottish Rural Development Programme the payback on this installation was achieved in very slightly over one year. Our client liked our biomass boiler so much he has built a second grain drier and ordered a further biomass boiler from Straw 4 Biomass which is twice the size of the original one taking his entire biomass output up to a little less than 1 mW
- Scientifically tested trials have confirmed that 2.67 tonnes of wheat straw produces the equivalent heat output to 1000 litres of heating oil.
- Adopting red diesel prices at 2011 harvest time and market prices for straw too the fuel equivalent cost for bales of wheat straw works out at less than 10 pence a litre. That is approximately 14% of the cost of red diesel!
- The larger the accumulation tank the less frequently you will usually have to fuel the burner (subject obviously to the amount of energy being drawn off the system)
- The accumulation tank (sometimes called a buffer tank) acts effectively as a battery of energy and because it is well insulated can hold temperature, even in periods of very cold weather for a lengthy period of time
- We took 20,000 litres of water sitting in an accumulation tank from 14 degrees Centigrade up to 85 degrees and burnt only three five foot round bales of wheat straw. This took just over five hours
- Renewable Heat Incentive payments are extremely attractive and this is something that ought to be thoroughly explored at every installation.
- A biomass boiler is no different to any other kind of boiler. Look after it and it will look after you
- The heat exchanger will require occasional cleaning and the soot should be swept out from time to time as well
- Fuel is the “F” word! Like any engine or boiler, if you put in dodgy fuel the performance will be impaired and you can also take years off the life of the boiler. It is recommended that you do not put in fuel that exceeds 20-25% moisture content
- Double check with your local Planning Offices and Environment Protection Agency to ensure that your proposals comply with all guidelines and planning restrictions.
