Pellet bin (definition)

Pellet hopper — is a specialized tank designed to store pellets used in solid fuel boilers and burners, and provides their automatic supply to the fuel chamber. The main function of the bunker is to accumulate a reserve pellet and ensure their continuous and metered supply to the boiler or burner, which allows for the automation of the combustion process and the maintenance of stable operation of the heating system.

Pellet bins can be made of various materials, including metal, plastic or composites, and come in different capacities, allowing you to choose the right option depending on the needs of a particular heating equipment and the available space for installation. The volume of the bin affects the frequency of its filling: the larger the capacity, the less often it needs to be refilled, which increases the ease of use of the system.

Pellet bunker: main functions and bunker equipment

1. Automatic feeding of pellets: Hoppers are often equipped with automatic feeding systems, such as augers or pneumatic conveyors, which transfer pellets from the hopper to the fuel chamber of the boiler or burner. This ensures continuous combustion and stable heat production.
2. Pellet level control system: Some bins are equipped with level sensors that monitor the amount of pellets inside the tank and can send a signal to the control panel or notify the user when the fuel supply needs to be replenished. This allows you to maintain a constant supply of pellets and avoid downtime in the heating system.
3. Anti-blocking mechanisms: To ensure reliable operation of the feed system, bunkers can be equipped with mechanisms that prevent pellets from getting stuck in the auger or pneumatic conveyor. This is especially important for maintaining a stable fuel supply, even when using pellets of different quality.
4. Insulation and moisture protection: Some bins may be equipped with insulation to protect the pellets from external influences such as moisture, which can negatively affect the quality of the fuel and make it difficult to feed.
5. Convenience of loading: It is important that the pellet bin is designed to accommodate pellets. Some models have large loading hatches or automatic filling systems from external storage sources.

Proper equipment and use of such a unit as a pellet bunker significantly increases the autonomy of the heating system, reduces maintenance time and ensures more stable and efficient operation of the boiler equipment.
