Pellet burner DOMNA ECO 50 KW

DOMNA ECO-50 Pellet Burner is a technologically advanced heating device from TechnoMaszBud, designed for users who expect high efficiency, ease of use, and energy independence.

The 50 kW power is a solution dedicated to larger homes, workshops, halls, farms, or industrial facilities.

The DOMNA ECO-50 burner is equipped with an automatic ignition system, a precise controller, and an effective self-cleaning system. As a result, the device provides almost maintenance-free heating. Automatic control eliminates the need for constant supervision, and the efficiency of up to 98% translates into real savings.

Operating Principle

Pellets from the tank are transported to the burner by a screw feeder, where they ignite on the grate. A blower fan supplies a controlled amount of air, which ensures optimal combustion conditions. The generated heat goes to the boiler, where it heats the water in the heating system. The entire process is monitored by the advanced PLUM controller, which manages air supply, pellet feed, and water temperature.

The set includes:

• Domna ECO-50 burner
• Controller with sensor set
• Screw feeder Ø63 x 1700 mm
• Pipe Ø50 x 1000 mm
• User manual
• (Optional: rotary safety valve)

Key advantages of the DOMNA ECO-50 pellet burner

• Ceramic combustion chamber in all burner models – ensures full and high-quality fuel combustion thanks to the creation of a thermal core. Heat is not transferred to the burner's chamber, and thus does not damage it, but remains inside the combustion chamber and acts as a kind of catalyst for complete fuel burnout. The flame from such a chamber becomes cleaner, and the amount of ash and clinker from low-quality fuel is reduced.
• Cast iron grates with lifetime warranty – you can confidently call them “eternal” – they do not burn out and do not deform at high temperatures, unlike stainless or regular steel grates. Cast iron grates perfectly hold the high temperature produced by the ceramic combustion chamber and work in perfect tandem with it.
• Cascade Cleaning System (CCS) – cascade self-cleaning system for the grates from ash, evenly distributes the fuel over the entire combustion area. It allows operation on low-quality pellets and effectively removes ash and other combustion residues. Cascade cleaning has been recognized in the market and by most equipment manufacturers as the most efficient and reliable. This system is used in all Domna burner models.
• Clever Air System (CAS) – intelligent system for splitting primary and secondary air and proportional mixing with the fuel, allows for maximum combustion efficiency (98%) and operational stability. The system enables the combustion of pyrolytic (pellet) gases released during pellet burning, which reduces fuel consumption and minimizes harmful emissions into the atmosphere.
• Ceramic igniter FKK (Japan) – the best igniters available on the market. They work quickly, are extremely reliable, and have a long service life—over 10,000 ignitions.
• ESC (Easy Service Cleaning) – easy access system to the combustion chamber and the burner grates block for service inspection and possible cleaning. No special tools are needed. The system allows the burner chamber to be cleaned without opening the boiler door, which is very convenient and saves time and effort.
• Fuzzy Logic – intelligent automatic burner power modulation system.
• Modern control system – the ability to manage the heating system and domestic hot water via the Internet or smartphone app, smart weather-based control—all of this is easily accessible with Domna burners.
• DSS (Domna Safety System) – a multi-level burner safety system that makes its operation pleasant and safe. Meets all fire safety standards for solid fuel combustion.
• Low emission levels – thanks to the ceramic combustion chamber, cast iron grates, and the CAS system, Domna burners emit significantly less harmful exhaust gases (CO, NOX, OGC) and dust into the atmosphere compared to solid fuel boilers or burners lacking these elements.
• The quietest pellet feeder – the pellet screw feeder made of high-quality plastic ensures the transportation process is practically silent. Additionally, it has a reduced friction coefficient, so the pellet is not crushed into dust and reaches the combustion chamber intact. This helps solve the problem of excessive dust during combustion.
• Easy to replace combustion chamber made of heat-resistant AISI 310S steel.
• Long service life of burners – thanks to components from global brands: Siemens, Lapp, Plum, MplusM.
• Automatic restart – automatic start-up and return to the set operating mode after a power outage.
• Warranty – 24 months

Applications

The DOMNA ECO-50 burner has been designed for use in larger facilities—both residential and commercial or industrial. It works perfectly in larger single-family homes, workshops, garages, agricultural boiler rooms, or production halls. Wherever an efficient, ecological, and low-cost heat source matters—DOMNA ECO-50 will meet your expectations.
