How Does Biomass WorkBefore trying to answer the question of how does biomass work, first we must summarize what biomass actually is. Biomass is a collective term to generalise a group of organic materials which can be used as an energy source. This includes wood, crop waste and purpose grown energy crops. Energy crops are biomass recourses which have been evaluated on their yield potential and other features. Not only must an energy crop generate high yields, but what is also important is how long it takes to produce that yield and how much time and money has to be spend on the crop. For example hemp is a biomass material which has huge potential, it has a wide range of uses and can be used a low ash, high energy content fuel. Importantly though hemp is very easy to grow, as it grows from seed and can be harvested in only 3 months. Hemp produces some of the best yields and requires virtually no fertilizers and maintenance. Biomass Resources and Renewable Fuel One of the key benefits of biomass over other forms of energy, specifically fossil fuels is the fact that biomass is a renewable fuel source. We can grow additional biomass to replace the resources we use, and within the life of its consumption. Biomass is also part of the natural carbon cycle, this means biomass combustion is actually carbon neutral unlike oil and gas combustion. Biomass is essential a form of stored solar energy. Through the process of photosynthesis energy from the sun is produced into cellulose. Biomass Furnace and Pellet Burners The traditional view as biomass as an energy source has been the log fire. However biomass now is a serious potential contributor to our energy requirements through upgrading the biomass. Biomass can be turned into gaseous energy, which can be used in internal combustion engines and turbines to generate electricity on demand. Biomass can also be processed into liquid fuels such as bio ethanol and bio diesel. However, in terms of heating applications, it makes more sense to use biomass in pellet form. Through a series of processes involving heat and pressure practically all biomass materials can be compressed into pellet form. Through producing a pellet the biomass gains a increase in density and a reduction in moisture content. With a uniform shape and size, pellets can flow in a similar fashion to liquids. This opens up a variety of potential uses. For example pellet burning solutions have a large hopper where the pellets are held, with an auger removal system at the base of the hopper. With other biomass materials in their raw form, material bridging and blockages are common. However pellets do not have this issue and more fuel can be stored in the hopper. How To Make Wood Pellets Information So in answering the question of how does biomass work, in this respect the question is how is a biomass pellet made. The central piece of equipment is the pellet mill. A pellet mill has two main components the die template and roller section. At the biomass enters the pellet mill, the roller section compresses the material through the die template. This generate immense heat which melt the biomass into pellet form. |
