Pellet boiler 70 kW FOCUS (13-80 kW), ash removal

Pellet boiler 70 kW FOCUS with ash removal for farms and suburban households

The 70 kW FOCUS automated pellet boiler with integrated industrial pellet burner and screw ash removal system is an energy-efficient and fully automated solution for heating facilities using agropellets with high ash content. This boiler, like its 60 kW version, is designed to operate in conditions requiring minimal human intervention, with an emphasis on cost-effectiveness and high performance.

Pellet boiler 70 kW FOCUS and its main advantages:

1. Efficiency of working with high-ash pellets:
   • Maximum ash pan and a built-in auger ash removal system ensure uninterrupted operation on fuel with an ash content of up to 10%, including agropellets (from seeds, straw, buckwheat, etc.).
   • Hybrid heat exchanger (plate and fire-tube) reduces thermal stress from the burner flame, while simultaneously settling heavy ash particles, which is especially important when working with agro-pellets.
2. High level of automation:
   • Automatic burner cleaning and transportation of ash into a common roll-away container minimizes manual labor.
   • Automatic ignition The use of ceramic spark plugs and automated fuel supply and ash removal processes ensure ease of operation.
3. Durable materials and reliability:
   • Steel 09G2S with a wall thickness of 6 mm for the heat exchanger and 4 mm for the external water jacket guarantees a long service life.
   • Thermal insulation from basalt mineral wool 50 mm thick effectively retains heat, reducing heat loss.
4. Flexibility and ease of installation:
   • Quick connection system Victaulic allows for quick and easy installation of the boiler, without requiring symmetrical tightening or welding at the installation site.
   • The cascade connection option allows adding boilers to increase the capacity up to 2.5 MW without changes to the main system.
5. Increased security and control:
   • Temperature sensors auger and infrared flame detectors control the safe operation of the burner, automatically shutting off the fuel supply in emergency situations. Which makes the 70 kW FOCUS pellet boiler an ideal choice for households.
   • Drive from Belimo with anti-jamming protection ensures reliable operation of the fuel stirring mechanism.
6. Convenient service:
   • Large hatches for easy access to the heat exchanger and ash pan, making maintenance and cleaning easier.
   • Manual loading is not provided.

Advantages of a built-in pellet burner:

• The 70 kW FOCUS pellet boiler operates both on woody, and on agropellets.
• Automatic ignition and a movable mono-grate for improved combustion and ash removal.
• Reliable components such as Swiss drives and heat-resistant materials ensure durability and resistance to high temperatures.

The 70 kW FOCUS pellet boiler is ideal for private homes, remote sites and small commercial premises, offering a combination of reliability, energy efficiency and ease of operation.

Functions and equipment

Functionality of the pellet boiler 70 kW FOCUS (13-80 kW):

• dynamic power 13 kW – 80 kW, controlled by a microcontroller;
• 5 levels of safe operation;
• fully automatic operation: ignition, extinguishing when the air temperature is reached, automatic ash cleaning during operation, cleaning the burner from ash when extinguished;
