Pellet boiler 120 kW FOCUS STONE (20-120 kW), ash removal

Pellet boiler 120 kW FOCUS STONE: your easy transition to automatic heating

Automated pellet boiler 120 kW FOCUS — is an industrial boiler with a built-in pellet burner, designed for highly efficient operation with agropellets and high-ash fuels. It is equipped with an automatic ash removal system and has minimal requirements for manual cleaning.

Pellet boiler 120 kW FOCUS STONE: main characteristics and advantages

• Increased capacity ash pan: Specially designed for use with high ash fuels such as agro pellets, allowing for significantly longer periods between cleanings.
• Screw ash removal system: Built-in automatic ash feed mechanism from the ash pan to the roll-away container minimizes manual maintenance work.
• FOCUS burner with high efficiency: Optimized for operation with wood and agro pellets, which makes the boiler universal and cost-effective. The automatic ignition and air supply adjustment system increases combustion efficiency.
• Hybrid heat exchanger: Plate and fire tube heat exchanger provides highly efficient heat transfer. The plate element relieves the thermal stress of the flame and filters heavy particles, reducing pollution.
• Convenient service: The 120 kW FOCUS pellet boiler is equipped with large doors that allow easy cleaning of the heat exchange surfaces. The ash chamber is located in front of the chimney for quick access.
• Pellet burner on the door: Mounted on reinforced hinges, which facilitates maintenance. The burner easily rolls away together with the door.
• Cold return protection: As an additional option, the boiler can be equipped with three-way valves and IMP Pumps, which will protect it from condensation and increase the efficiency of the 30%.
• Easy to install: The 120 kW FOCUS pellet boiler is equipped with the Victaulic quick-connection system, which ensures fast and high-quality connection without the need for symmetrical tightening.
• Modularity and scalability: The boiler can be used in cascade systems to increase the capacity up to 2.5 MW, making it ideal for large industrial facilities.

Additional features:

• Materials: The heat exchange part is made of 09G2S structural steel with a thickness of 6 mm, and the outer shell is made of AISI201 stainless steel.
• thermal insulation: Basalt mineral wool 50 mm thick.
• Automatic burner cleaning: The burner is cleaned into the general ash removal system, ensuring continuous operation on high-ash pellets.
• Safety: Built-in temperature and flame sensors provide control and protection against emergency situations. The fuel supply line is equipped with a rupture mechanism to improve operational safety.

Advantages of the FOCUS pellet burner:

• Automatic ignition using Japanese ceramic candles.
• Stainless steel movable grates, ensuring uniform combustion and ash removal.
• Precise air control for efficient combustion of fuel with highly efficient supply of primary and secondary air.

Automated pellet boiler 120 kW FOCUS STONE — is a reliable solution for industrial and commercial facilities requiring efficient and economical heating using various types of pellet fuel, including agropellets.
