Making Good Fuel For The Biomass Burner With A Pellet Press
There are many different types of biomass burner. These include basic log stoves and boilers, straw bale burners, wood chip boilers and wood pellet stoves and boilers. As biomass refers to a collective of many different forms of organic material that can be used as a fuel, a true biomass burner must be able to burn a wide variety of biomass. The problem is biomass grows in various different shapes and sizes. Therefore to use all different forms of biomass in one burner, the biomass must first be made into a standardised shape, size and density, essentially a pellet.
A pellet is simply a compressed form of the original raw material. That raw material could be wood, however it could equally be any type of straw or grass or practically any other type of biomass residue. Through processing the biomass into pellets in a pellet press it makes it much easier to design a biomass burner which can efficiently work with the fuel.
Renewable and Alternative Energy
Biomass is also referred to as an alternative energy source, as apposed to oil, gas or coal. However really mankind relied on biomass for hundreds of years, and really fossil fuels are the alternative. However it is now becoming more clear our reliance on fossil fuels is not sustainable and has many other short comings. For example fossil fuels are one of the main contributors to increasing the rate of global warming. The combustion of fossil fuels released additional carbon dioxide into the atmosphere. Carbon dioxide acts like a mirror reflecting more of the energy from the sun back at the earth. Biomass on the other hand has been made from carbon which is already part of the natural cycle, and its combustion does not increase the level of carbon dioxide present. The pellet press can help.
Not only does turning wood or any other form of biomass into pellets give it a uniform shape and size it also gives it an improved density. Fuel density is very important for efficient combustion. A fuel with a higher density will burn much more cleanly, producing less smoke, less particulate emissions, less ash and importantly more heat. As each pellet has roughly the same amount of energy, it is very easy for the biomass burner to regulate temperature by feeding the required number of pellets into the fire. This means biomass pellet burners require much lower levels of maintenance, compared to say basic log stoves. Pellet boilers are also much more superior to wood chip boilers. Wood chip boilers can have issues with chip size, if the wrong type of chipper is used, the chips will not be small enough to flow into the boiler properly. Also, there are a wide range of differences in the moisture content of the chips supplied. Click below.
