Pellet boiler 70 kW FOCUS (13-80 kW), ash removal + pneumatic cleaning of heat exchanger

Automated pellet boiler 70 kW FOCUS: Ideal choice for office, farm and household

Pellet boiler 70 kW FOCUS (13-80 kW) is a fully automated solution for facilities that require a stable heat supply. It is equipped with an industrial pellet burner and a variety of systems to improve operating efficiency and reduce the need for manual cleaning. This boiler is designed to operate with high-ash agropellets, making it an ideal choice for agricultural facilities, manufacturing plants and greenhouses.

Main components and characteristics

1. Pellet burner

The FOCUS boiler burner is designed to operate with wood and agro pellets with an ash content of up to 10%, including pellets from sunflower waste, corn, rice, furniture and straw.

Burner features:

• Automatic ignition using Japanese ceramic candles for contactless air ignition.
• Movable mono-grid for stirring and removing ash.
• Fuel feed auger with temperature sensor for safety.
• Infrared flame sensor to control the presence of fire and ensure safe operation.
• Proportional supply of primary and secondary air for optimal fuel combustion.
• Reliable drive from the Swiss company Belimo with protection against jamming.

2. Heat exchanger

The 70 kW FOCUS pellet boiler has a hybrid heat exchanger that efficiently processes thermal energy from the flare burner.

Heat exchanger features:

• Plate heat exchanger relieves primary thermal stress and precipitates heavy ash particles.
• Developed convective part with horizontal heat exchanger ensures maximum thermal efficiency.
• Ease of maintenance: large hatch and ash chamber in front of the chimney for easy cleaning.

Automation and ash removal systems

1. Screw ash removal system

The 70 kW FOCUS pellet boiler is equipped with a screw ash removal system that transports ash into a roll-away container, reducing the need for frequent maintenance and increasing the intervals between cleanings.

2. Pneumatic heat exchanger cleaning system

An automatic pneumatic system with a receiver and solenoid valves keeps the heat exchanger clean, preventing ash accumulation. The solenoid valves are powered by 24 V DC.

3. Control system

The 70 kW FOCUS pellet boiler is equipped with an automatic power adjustment system in the range from 18 to 80 kW, automatic ignition, extinguishing and cleaning cycle control. Integration with smart home systems and control of heating and hot water supply pumps is possible.

Efficiency and protection

1. Protection against cold return and condensation

Additional equipment with three-way valves protects the boiler from cold return, prevents condensation and increases efficiency on the 30%.

2. Installation flexibility and cascade connection

The Victaulic quick-connect system simplifies boiler installation, eliminating welding. The boiler can be installed in cascade with others, providing a total system capacity of up to 2.5 MW.

Strength and durability

1. Body materials

The body is made of structural steel 09G2S, with a wall thickness of 6 mm, which guarantees durability and resistance to high temperatures. Thermal insulation made of basalt mineral wool and an external casing made of stainless steel AISI201 provide protection from external influences.

2. Ease of maintenance

Adjustable hinges and locks simplify operation, and the ability to change the direction of door opening adds flexibility in installation and maintenance.

Additional features and guarantees

1. Built-in safety features

The 70 kW FOCUS pellet boiler is equipped with sensors for monitoring temperature, flame and other critical parameters, which ensures safe operation even in industrial conditions.

2. Warranty and compliance with standards

The 70 kW FOCUS pellet boiler complies with GOST 32452-2013 (EN 15270:2007) and has a 12-month warranty.
