Wood Pellet Boilers and Wood Chip Boilers
Although it seems like a new phenomenon, wood was of course the main fuel available before fossil fuels. Due to global warming and the turbulent prices of fossil fuels many organisations are seeking alternative fuels and are aiming to become more energy self-sufficient. Wood pellets and wood chips are reliable sources of fuel which are becoming more popular due to their low price and sustainability. This popularity has led to the creation of new jobs and a new industry in the UK.
Eco Link has recently installing Wood Chip and Wood Pellet boilers for many years and we have a wealth of clients which have benefited from this energy efficient, reliable and low cost fuel. Recently, Eco Link has undertook a project to help leading UK supermarket Sainsbury's reach their goal of using a sustainable fuel for over 60 supermarkets and during 2011 and 2012 . These have been delivered in the form of modular units that will heat and provide hot water for the stores. The units house both the wood pellet boiler in one side and the other side stores the pellets ready for use.
At Eco Link we are specialists in renewable energy and we will listen to our clients' requirements carefully and are confident we can provide a biomass system which will suit any high specification . Eco Link's service is underpinned by our trusted maintenance contracts to ensure that if there were to be a problem our qualified engineers will immediately resolve any issue.
Wood Pellets are made from natural wood. They are dry and usually have less than 10% moisture. A fine wood substance is compressed through a cylinder which can then disintegrate. The cylinders are small at 10cm diameter and the concentrated compression makes them very dense; this factor leads them to have one of the best energy efficiency ratings when compared to other fuels.
Wood pellets also offer other distinct advantages:
- They are one of the most cost effective fuels on the market.
- You'll no longer have to rely on fuels which are in an unstable international market
- The fuel is from a sustainable and safe supply this is due them being sourced from UK wood residues.
- They offer a consistent calorific value so are reliable
- They can be efficiently stored and transported this is due to their high density being a high bulk density per m3 than wood chip. Good quality wood pellets have a bulk density of about 600-700kg/m3 as opposed to wood chip (assuming 25% moisture content) which will have a bulk density of about 200-350kg/m3 depending on wood type.
Wood harvested from many sources can also be chipped to provide fuel for biomass boilers.. When using wood chip as a fuel, consideration must be given to the chips moisture content, wood type and chip size. Wood chips,no larger than 16mm can be used to fuel a biomass boiler which a great alternative to fossil fuels. The size has to be specific to ensure they will work effectively also it is essential that they are dried to the correct level of 25% moisture content. The way in which the chips are transported and stored is also crucial to ensure chips are in the right condition, this is due to the efficiency of the wood being linked closely to the moisture content of the wood when it is burnt in the boiler.
Mainly used in commercial organisations, wood chip boilers can be used for the heating of a block of flats, office, shopping centre or airport complexes, or similar size buildings. Wood chips, which can be for many different sources, are delivered by lorry directly to the site and usually deposited into a hopper or silo.
