The FOCUS 140 kW pellet boiler is equipped with an industrial pellet burner and a screw ash removal system. The main purpose is highly efficient operation with agropellets, where continuous heat removal with minimal maintenance is important.

Pellet boiler FOCUS STONE 140 kW: design and main elements

• Auger ash removal system: Built-in auger for automatic ash transport to the roll-away container extends the periods between cleanings, reducing the need for manual maintenance.
• Pneumatic cleaning of heat exchanger: ensures cleaning of heat exchange surfaces using a pneumatic device equipped with a receiver and is controlled by the boiler automation.
• Roll-off container: high capacity ash pan with a system for transferring ash into a container for easy disposal.

Efficiency and heat removal

• Hybrid heat exchanger: consists of a plate and a fire-tube part. The plate part removes the primary thermal stress and precipitates heavy particles from the fuel, and the developed convective fire-tube part ensures high efficiency.
• Optimized for agropellets: the design was developed taking into account operation on high-ash fuel (ash content up to 10%), which increases the efficiency and profitability of the boiler when using available raw materials.

Easy to install and operate

• Victaulic Quick Couplings: a convenient connection system that does not require welding allows for quick installation of the boiler and allows for minor distortions during installation.
• Additional harness (optional): to protect against cold return, the boiler can be equipped with a three-way or four-way valve with IMP Pumps, which extends the service life and improves heat removal.

Benefits of a built-in pellet burner

The burner TM "FOCUS" is adapted for both wood and agro pellets. Its main elements include:

• Automatic ignition: Japanese ceramic candles for contactless air ignition.
• Stainless steel movable grates, ensuring uniform combustion and ash removal.
• Temperature and infrared sensors: control radiation levels and temperature, increasing the safety and stability of the burner.
• Air Proportions: adjustable ratio of primary and secondary air improves the combustion process.

Materials and Durability

• Housing and heat exchanger: made of 09G2S structural steel, and 50 mm thick basalt wool is used for thermal insulation, which helps reduce heat loss.
• Ease of maintenance: large door opening for easy access to heat exchanger and ash pan, adjustable hinges and locks ensure tight door fit.

The FOCUS 140 kW pellet boiler is suitable for both private households and commercial properties, providing reliable, automated heating with minimal maintenance costs.
