There are many unlike types of biomass burner. These include basic log stoves as well as boilers, grass bale burners, biomass chip boilers plus wood pellet stoves plus boilers. As wood refers to a collective of many unlike forms of natural material that can be used as a fuel, a true biomass burner must be able to burn a wide variety of wood. The problem is wood grows in a variety of diverse shapes along with sizes. Therefore to use all dissimilar forms of wood in one burner, the wood must first be made into a standardised shape, size as well as density, essentially a pellet. A pellet is simply a compressed form of the original raw matter. That raw matter could be wood, on the other hand it could equally be any type of grass or straw or practically any other type of wood residue. Owing to processing the wood into pellets it makes it much easier to design a biomass burner which can efficiently work by the fuel. Therefore wood pellet stoves as well as pellet boilers are the only true wood burner.

Wood is also referred to as an renewable fuel source, as apposed to oil, gas or coal. Yet really mankind relied on biomass for hundreds of years, as well as really fossil fuels are the renewable. Though it is not becoming more clear our dependence on fossil fuels is not sustainable as well as has many other short comings. For instance fossil fuels are one of the main contributors to growing the rate of global warming. The incineration of fossil fuels released additional carbon dioxide into the atmosphere. Carbon dioxide acts like mirror reflecting more of the energy from the sun back at the earth. Biomass on the other has it manufactured from carbon which is already part of the unrefined cycle, plus its incineration does not increase the level of carbon dioxide present. Also biomass is a renewable for of energy, as we can quickly grow more wood to replace the resources we use. However fossil fuels are formed over thousands of year, therefore we cannot replace those resources, so once they are gone, that’s it. In addition to India and China developing at unprecedented rates with the two largest global populations our source of fuel along with our attitudes to how we use it have go to change.

Not only does turning wood or any other form of biomass into pellets give it a uniform shape along with size it also gives it an improved density. Energy density is very important for efficient incineration. A fuel with a higher density will burn much more cleanly, generating less smoke, less particulate emissions, less ash and importantly more temperature. As each pellet has roughly the same amount of energy, it is very easy for the biomass burner to relate temperature by way of feed the required number of pellets into the fire. This means biomass pellet burners necessitate much lower levels of maintenance, compared to say basic log stoves. Pellet boilers are also much more superior to biomass chip boilers. Wood chip boilers can have issues by means of chip size, if the wrong type of chipper is used, the chips will not be small sufficient to flow into the boiler properly. Also, there are a wide assortment of differences in the moisture content of the chips supplied. Moisture obviously impacts directly on the heat generated.
