Pellet boiler 700 kW FOCUS (300-750 kW), ash removal and pneumatic cleaning

Automated pellet boiler 700 kW FOCUS with built-in screw ash removal system pneumatic cleaning of heat exchanger with receiver

The 700 kW FOCUS pellet boiler, thanks to the installed automation, supports the control of the heat exchanger pneumatic cleaning cycles.

The 700 kW FOCUS automated pellet boiler is designed for maximum efficiency with flare pellet burner on high-ash agropellets. The main emphasis is on cost-effectiveness, minimization of manual labor during cleaning of the boiler and heat exchanger, as well as automatic ash removal into roll-away containers, which increases the time between maintenance and payback of the equipment.

Main advantages :

The 700 kW FOCUS automated pellet boiler has a number of key features aimed at increasing efficiency and simplifying maintenance, especially when using agropellets with high ash content.

Main advantages:

• Enlarged ash pan: The boiler is equipped with a large ash pan, which allows for efficient operation with high-ash pellets, minimizing the frequency of cleaning.
• Screw ash removal systems: Built-in augers automatically transport ash from both the boiler ash pan and the space under the burner grates, moving it into external roll-away containers. This significantly simplifies the maintenance process, eliminating the need for manual removal of ash residues.
• Automatic pneumatic cleaning: The 700 kW FOCUS pellet boiler is equipped with a pneumatic heat exchanger cleaning system, which is controlled by built-in automation. This function helps maintain high heat exchange efficiency by cleaning surfaces from settling particles and preventing their accumulation.
• Hybrid heat exchanger: The combination of the plate and fire-tube design of the heat exchanger allows for the effective removal of thermal stress from the burner and the simultaneous deposition of heavy particles of volatile components of the torch. This solution ensures a more uniform heat exchange and reduces the risk of overheating of individual sections of the boiler.
• Ease of maintenance: The well-thought-out design of the boiler includes a wide hatch for easy access to the heat exchanger, as well as a horizontal cleaning system. Large doors and convenient arrangement of elements allow for quick and easy maintenance.
• High capacity ash pan: The ash pan capacity is designed for long-term operation under industrial conditions, which allows the boiler to operate on high-ash pellets without frequent interruptions for cleaning.
• Modular system: The 700 kW FOCUS pellet boiler supports cascade assembly, which allows increasing the capacity of the installation as needed. Thanks to the presence of three-way valves and a hydraulic arrow, each boiler in the cascade can be switched off without affecting the operation of the system as a whole. This makes the FOCUS boiler a flexible solution both for the initial stage of construction and for increasing capacity in the future.
• Construction made of quality materials: The 700 kW FOCUS pellet boiler is made of high-quality structural steel grade 09G2S with a wall thickness of 6 mm for the heat exchange part and 4 mm for the water jacket. Basalt wool with a thickness of 50 mm is used for thermal insulation, which allows minimizing heat loss.
• Durable elements: The boiler casing is made of stainless polished steel, which ensures durability and resistance to external influences. Adjustable hinges and locks of the ash pan and heat exchanger doors allow them to be tightly closed, which improves the tightness and efficiency of the boiler.
• Additional features: The 700 kW FOCUS pellet boiler can be additionally equipped with three-way or four-way valves with IMP Pumps to protect the system from cold "return", which prevents condensation and increases the efficiency of the boiler by 30%. Also, for ease of installation, Victaulic quick connections are used, which do not require symmetrical tightening and allow installation without welding.
• Installation flexibility: Thanks to the Victaulic system, the installer can allow small deviations from the design dimensions of the room (up to 2-3 degrees), which simplifies installation in real conditions.

Thus, the FOCUS pellet boiler combines a high level of automation, ease of operation and maintenance, as well as the economic feasibility of using high-ash pellets. This makes it an excellent choice for industrial facilities, greenhouses and other enterprises with high heat requirements.

 Pellet burner TM "FOCUS"installed in this kit will work both on clean wood pellets and on agro-pellets with ash content up to 10% (pellets from seeds, corn, buckwheat, rice, furniture, straw).
