Engineered for rigorous thermal processing environments, this industrial natural gas burner integrates highly optimized combustion technology to deliver exceptional reliability and strict emission control. Facility managers and procurement teams evaluating heating solutions will find that this unit significantly lowers long-term operational costs through superior fuel-to-air mixture precision. Beyond standard operational metrics, the system achieves ultra-low NOx and CO2 emissions, ensuring your facility easily meets and exceeds stringent environmental compliance regulations without sacrificing thermal output.
Wide Power Range: The burner operates efficiently across a dynamic capacity range of approximately 250 to 1550 kW, making it highly adaptable for medium to large-scale industrial heating needs and fluctuating thermal demands.
Advanced Regulation Options & Energy Savings: Includes sliding two-stage and modulating control for precise fuel and air mixture regulation. The modulation feature allows continuous adjustment of the flame output to perfectly match heat demand, dramatically enhancing thermal efficiency and reducing overall natural gas consumption.
Automatic Operation Sequence: Equipped with a highly responsive automatic combustion sequence that meticulously manages pre-purge, ignition, continuous flame monitoring, and safe shutdown protocols.
Flame Supervision: Uses sensitive ionization principle flame sensors for natural gas operation, ensuring immediate, safe, and stable flame detection. Dual fuel variants employ UV diode flame sensors for uncompromising accuracy.
Quiet and Stable Operation: The dynamically balanced fan and precision-machined combustion head design ensure a stable combustion process characterized by a low-decibel acoustic profile, minimizing workplace noise pollution.
Easy Maintenance: The heavy-duty hinged burner casing provides a solid, tactile feel while allowing immediate access to internal components. The adjustable combustion head simplifies installation, routine servicing, and long-term maintenance.
Fuel Flexibility: While optimized for natural gas, the burner's versatile design allows for straightforward conversion to Liquid Petroleum Gas (LPG) without significant mechanical modification—requiring only standard recommissioning.
Safety Compliance & Certifications: Strictly adheres to international quality management systems. It complies fully with EN 676 for gas burners and includes mandatory safety components such as double solenoid valves (Class A), gas filters, and pressure regulators. Valve proving systems are strongly recommended for outputs above 1200 kW. Furthermore, it meets CE and ISO industrial safety standards.
Evaluating the exact specifications of your thermal equipment is critical for ensuring seamless integration into existing infrastructure. The following technical data outlines the precise operational boundaries and component specifications of the 1550 kW burner. Designed to operate reliably in ambient conditions ranging from -10°C to +40°C, the robust electrical and mechanical framework guarantees consistent performance. The integration of Class A double solenoid valves and comprehensive gas pressure compatibility ensures that the unit maintains exact combustion parameters even under fluctuating municipal or industrial gas supply pressures.

The physical architecture of the burner is purposefully engineered to minimize spatial footprint while maximizing component accessibility. We provide comprehensive dimensional data, exact weight specifications, and spatial planning guidelines to ensure procurement teams can seamlessly integrate the unit into existing boiler rooms or dense manufacturing floors. The burner integrates all critical mechanical and electrical components into a highly compact, modular assembly, featuring rugged metallic housings that protect internal mechanisms from industrial particulate matter and ambient moisture.
Motor and fan unit aligned perpendicularly to airflow for optimized combustion air supply, reducing internal turbulence.
Combustion head with an easily adjustable, heavy-gauge flame tube designed to match specific appliance dimensions and heat distribution requirements.
Comprehensive gas valve train including industrial-grade double solenoid valves and a precisely machined gas butterfly valve.
High-voltage ignition system complete with a durable transformer and wear-resistant electrodes.
Servomotor-driven cams crafted for synchronous, lag-free gas and air regulation.
Optional integral or separate control panels equipped with intuitive visual interfaces, flame supervision, and hardwired safety interlocks.
Upon burner start-up, a meticulously controlled ignition sequence initiates. The system first purges the chamber, followed by the release of a precisely measured, small ignition load of gas to establish a highly stable pilot flame. You can distinctively hear the quiet, solid engagement of the internal valves as this process occurs. After strict ignition confirmation, the burner smoothly transitions to main flame operation with modulating or staged fuel input intelligently controlled by the servomotor. This gradual, calculated regulation ensures minimal combustion chamber disturbances and actively prevents dangerous pressure surges in the broader gas system during shutdown by enabling partial load shutdown control.
Our product operates on the exact same proven working principle as the Weisaupt G7 Gas Burner, utilizing continuous, real-time flame monitoring via sensitive ionization sensors that automatically manage an immediate safety shutoff if flame stability is compromised in any way. For dual fuel models, robust magnetic clutches physically disconnect the oil pump when operating on gas. This mechanical separation eliminates unnecessary friction, drastically reducing component wear and extending the overall lifecycle of the pump mechanism.
Built to sustain continuous, heavy-duty operation, this burner serves as the reliable thermal core for a wide spectrum of industrial facilities. Supported by numerous successful case studies in large-scale manufacturing environments, it has consistently demonstrated its ability to maintain exact temperature profiles during critical production cycles. This burner is ideal for use in:
Industrial hot water and high-pressure steam boilers utilized in chemical processing and textile plants.
Large-scale air heating systems for expansive warehouses and commercial structural drying.
Process heating in manufacturing, including metallurgy, food and beverage processing, and automotive parts curing.
Modern high-capacity boiler installations requiring uncompromising reliability and exceptionally clean combustion.
It can be confidently compared to well-known industrial burners like those from other established German manufacturers, matching their rigorous performance in terms of thermal efficiency, structural longevity, and strict emission control.
