The hardness and wear resistance of energy-saving biomass burning pellets are important physical properties, which have a profound impact on their production, transportation, storage and application in combustion equipment.
In terms of hardness, energy-saving biomass burning pellets usually have moderate hardness. Its hardness is enough to maintain good shape stability during the processing and molding process, and it will not be easily deformed or broken. For example, when the pellets are extruded by high pressure in the pelletizer, they can withstand a certain pressure and form a tight and regular shape, which provides convenience for subsequent packaging, transportation and storage. However, its hardness is not too high, because too high hardness may have an adverse effect on the feeding system and combustion process of the combustion equipment. During the feeding process, overly hard pellets may cause excessive wear on components such as the feeding screw and conveyor belt, increasing the maintenance cost and failure rate of the equipment.
In terms of wear resistance, energy-saving biomass burning pellets show certain characteristics. In the transportation link, whether it is transported in bags or in bulk, friction will occur between pellets and between pellets and transport containers. Due to its certain wear resistance, the pellets can maintain their integrity during short-distance transportation and reduce dust and debris caused by friction. However, in the case of long-distance transportation or multiple transfers, although its wear resistance can resist friction loss to a certain extent, it is inevitable that a small amount of pellet surface wear will occur, resulting in some fine powder. If these fine powders accumulate too much, they may affect the fluidity and combustion performance of the pellets. Therefore, in some application scenarios such as large biomass combustion power plants, corresponding dust removal and powder handling equipment will be equipped.
During storage, the wear resistance of energy-saving biomass burning pellets also plays a role. When the pellets are piled together, the pellets at the bottom will be under certain pressure and rub against the surrounding pellets. Good wear resistance enables the pellets to maintain their shape and structure during storage, and will not be broken or pulverized in large quantities due to long-term extrusion and friction, thereby ensuring the stability and safety of storage and reducing energy waste and potential safety hazards caused by pellet deterioration.
In short, the hardness and wear resistance of energy-saving biomass burning pellets have been reasonably optimized. While ensuring their smooth circulation in various links, it also lays a solid physical foundation for them to efficiently and stably play an energy role in a wide range of application scenarios.
