- Structure and Components:
- The burner typically includes a large firebox with a water jacket for heat transfer.
- A multi-pass heat exchanger with 20-24 fire tubes and turbulators enhances heat transfer.
- Refractory lining is used to ensure a hot, clean, and efficient burn.
- It has a self-cleaning burn head for optimal efficiency.
- Includes combustion fans with negative and positive pressure suction and a European style rotary air valve for burn back protection.
- The fuel system usually includes a heavy-duty variable speed gearbox, auger system, and a chip bin for fuel storage with a moving fuel floor to prevent bridging and a positive airlock.
- Features:
- Heat output ranges from 100,000 to 700,000 BTU.
- Wi-Fi connectivity allows remote monitoring and adjustment of water temperature, fuel feed, and air volume for efficient combustion.
- Ash removal system includes an auger and ash bin needing service approximately once a week.
- Maintenance and Service:
- Regular cleaning and inspection are necessary to maintain efficiency and safety.
- Ash collection containers need weekly emptying.
- Control devices should be monitored for combustion and stack temperature, fuel consumption, and boiler operation.
- After one heating season, remove unused pellets from hopper to prevent rust damage.
- Yearly maintenance includes greasing moving parts like augers and gearboxes and checking for wear on conveyors, motors, and gearboxes.
- Certified chimney sweeping and inspection before each heating season are recommended.
- Operational Tips:
- Use only dry, clean wood pellets designed for pellet appliances.
- Ensure proper installation and exhaust systems are in place.
- The burner will take a few minutes to light and establish a fire.
- Adjust heat output as needed once the fire is established.
This type of burner is useful for heating buildings, domestic hot water, pools, and more, providing a commercial-scale biomass heating solution with user-friendly and efficient design features
