There are several easy ways to determine the quality of wood pellets. Good pellets should be shiny and smooth with no cracks. They should also pass a snap test. If you don’t have special tools, you can use a plastic bottle to test the pellets. Read on for more information. Also, read on for some helpful hints. Here are some of them: Good quality wood pellets should be smooth and shiny During the manufacturing process, pellets should be dry and break with characteristic click. They should be shiny and free of impurities and should be made from fresh wood or pure plant components. Avoid pellets made from sunflower or other types of non-wood plant material as they are black in color and have high ash content. As an alternative to wood pellets, you can buy dkbraende pellets, which contain higher ash content. When purchasing pellets, you can check the quality of raw materials by checking the color and smell. White-yellow pellets are usually made from waste wood from furniture production, while brown pellets are made from raw materials that have been processed with bark and have been stored for a long time. Pellet color is not necessarily a quality criterion, but it can be an indication of the raw materials used, the pelleting process, and the storage process. Pellets should smell of the wood from which they were made, but they should not have a musty smell, which is an indication that the pellets were stored for a long time. They should have no cracks To choose wood pellets that are free from cracks and other imperfections, look for a smooth, shiny surface and no longitudinal cracks. These are signs that a pellet has the right compression ratio and is not full of additives. Additionally, if the wood pellets are dark or have a peculiar color, this could indicate that the pellets are not completely free of additives. To prevent this problem, many pellet manufacturers add oils or other ingredients to the wood pellets or machinery. However, these additives reduce the amount of heat produced and increase emissions. The apparent depth of surface cracks was measured using the built-in tool of a digital microscope. The built-in tool simulated 3D surface profile measurement of the front face of a pellet using multi-lighting and photographic stitching. After analyzing all images, a line was drawn between two points that were in the same plane and the same depth. Cracks in pellets that had been stored for a month were found to have a significantly lower apparent depth after storing. They should not be damp One of the easiest ways to determine the quality of wood pellets without the use of special tools is by smelling them. Good quality pellets should smell like fresh wood. If they do not, they are probably not pure. Occasionally, wood pellets with binder have been mixed into the raw material to make it stickier. This can be easily corrected with some simple tests. Then, smell the pellets again to ensure that they are still of good quality. Using a container with a liter-sized capacity, weigh the contents in the bottle. Add wood pellets and water, then weigh the contents. Then, subtract the bottle weight from the total weight of the wood pellets. A high-quality pellet has a specific gravity between 0.6-0.7 kg/L, while a low-quality one is easy to break. In the case of wood pellets that have too many fines, they are not conditioned properly. They should pass the snap test Before buying your next bag of wood pellets, you’ll need to determine the quality of the materials. Good quality pellets burn easily and produce a light yellow or brown flame. Bad quality pellets contain fillers or other types of non-pure raw material. The smoother the surface of a pellet, the higher its quality. Better quality pellets leave less ash. Below are some tips for determining the quality of wood pellets. A wood pellet is usually made from compressed sawdust, a byproduct of other industries. The natural lignin in wood holds the pellets together. It makes up approximately one third of the dry mass of a wood log and is the substance responsible for the wood’s strength and water proofing properties. Wood pellets are also extremely dense and have a low moisture content. This ensures high combustion efficiency and fine calibration. Their small size makes them easy to store and transport over long distances. They should be free of impurities You can easily determine the quality of wood pellets by looking at them. For instance, if the wood pellets are light in color and have a low moisture content, they are likely to burn easily. The lower their moisture content, the more dense they are and the less prone they are to breaking and producing powder. This means that high-quality pellets should have a specific gravity of 0.6 to 0.7 kg/L. If you’re making pellets yourself, it’s easy to check their consistency by mixing them with a kitchen stand mixer and a few drops of vegetable oil. Mix the raw material for 10 to 20 minutes. Sawdust doesn’t require mixing since it’s already consistent in shape. Pellet mills usually run at a temperature of 170-190 degrees Fahrenheit. If you find the wood pellets are discolored or unrecognizable, it’s time to make some adjustments. They should have a PFI certification In addition to the PFI certification, you should look for the mass of wood pellets per cubic foot. Pellets with a higher bulk density can better burn. To measure the density, you can use a kitchen scale or any other scale that can handle a weight of more than 1 litre. Fill a measuring vessel with water and weigh the contents of the container. Then, divide the weight by two and multiply by the number of cubic feet. Wood pellets produced in a factory with a PFI certification should have uniform diameter and length. Improper pellet size alters combustion conditions and reduces efficiency. PFI or ENPlus certifications require that pellets have a diameter of 6 to 8 millimeters and a length of 3.15 to 40mm. Durability is also an excellent representative of the quality standards of wood pellets. PFI and EN Plus standards require wood pellets to have a durability rating of greater than 95%.Read More
