Types of Pellet Burners (Definition)

Types of pellet burners - these are different types of burners designed for combustion pellet (biomass pellets) in heating systems. Each of them has its own characteristics that make it more suitable for certain operating conditions.

Main types of pellet burners:

1. Auger pellet burners:
   • Description: These burners use a screw mechanism to feed pellets from the hopper into the combustion chamber. The screw mechanism ensures a continuous supply of fuel and uniform combustion.
   • Advantages: Simple design, reliability and the ability to adjust the fuel supply.
   • Application: Widely used in domestic and small commercial heating systems.
2. Vacuum pellet burners:
   • Description: Vacuum burners use a vacuum pellet feed system that creates pressure to move the fuel into the combustion chamber.
   • Advantages: High degree of automation and the possibility of supplying fuel from a remote bunker.
   • Application: Suitable for large heating systems and industrial facilities.
3. Falling fuel burners:
   • Description: In such burners, pellets fall into the combustion chamber under the influence of gravity. Fuel can enter the combustion chamber through a special hole or a trapezoidal channel.
   • Advantages: Simple mechanism requiring minimal maintenance.
   • Application: Typically used in less complex heating systems.
4. Burners with fan:
   • Description: These burners are equipped with a fan that provides additional air supply to improve the combustion process and increase efficiency.
   • Advantages: Improved combustion efficiency and the ability to adjust the combustion process.
   • Application: Suitable for systems where a high level of control over the combustion process is required.
5. Combined fuel burners:
   • Description: These burners can operate on pellets or other types of fuel, such as wood or coal. They are equipped with systems that allow you to switch between different types of fuel.
   • Advantages: Flexibility in fuel choice and the ability to adapt to changing conditions.
   • Application: Suitable for users who want to use multiple fuel types to optimize costs.

Operating principles of pellet burners:

• Automation: Most pellet burners are equipped with automatic control systems that regulate the supply of fuel and air to ensure efficient combustion.
• Control systems: Burners can be equipped with thermostats, sensors and controllers for automatic regulation of the system. The main types of pellet burners do not imply this, but automation is offered by manufacturers.

Application:

• Domestic heating: In private houses and small apartments, to provide heating and hot water supply, select types of pellet burners in combination with a boiler to take into account the operating conditions.
• Commercial and industrial properties: In larger heating systems where high power and flexibility in fuel use are required.

What does the choice of a pellet boiler and burner depend on:

The choice of pellet burner type depends on the needs of the heating system, the type of fuel, the available space and the automation requirements. Different types of burners offer different benefits and functional features that can be adapted to specific operating conditions.
