Commercial Biomass Boilers
What is a biomass boiler?
Biomass boilers are an eco-friendly way of obtaining power especially for small businesses, by burning biological products including wood pellets, plants, straw and woodchip. The pellets consist of low grade waste from the wood industry such as sawdust and shavings and they are produced in bulk. They are pressed in to moulds to form the pellets. When burnt the pellets are around forty per cent cheaper than ordinary heating oil and produce the same sort of heat. They also require less space for their storage than things like wood chips.
For commercial use the boilers usually range from two hundred kilowatts through to five megawatts. The wood pellets they burn can contain moisture of up to forty five per cent. This type of boiler is made from thick steel with a lot of aluminium content and the combustion chamber is high volume.
What features does a biomass boiler have?
All commercial biomass boilers have safety valves to prevent explosion if there is too high a rise in pressure and they also have temperature controls that are fully adjustable. They also have flues that open to allow inspection for damage and maintenance on a regular basis. They also allow for any combustion debris to be removed.
The actual chamber has a thick lining which is made largely from aluminium and bricks so that it can reach very high temperatures to ensure that combustion happens in the most effective way possible. This chamber can withstand temperatures from 900 to 1300 degrees centigrade. They also have smoke filters fitted that trap any ash or other particles from the combustion of the fuel. Most biomass boilers also have an area specifically for collecting any ash from the fuel when it is burnt.
What are the benefits to my company?
The primary benefit to any company is the reduction in their fuel bills when using a biomass boiler in preference to a normal one. The main source of energy for biomass boilers is the suns energy stored via photosynthesis which can then be used via combustion.
Although this process produces and releases some CO2 in to the atmosphere it is no more than the amount absorbed by the plants made in to the fuels used by the boiler. Biomass fuel is therefore regarded as being a low carbon technology, especially if the biomass fuel used is from sustainable sources. The way Commercial biomass boilers burn fuel and the biomass fuel they use make them as convenient to use and have installed as fossil fuel boilers are.
