Dunphy burners are equipped with advanced controls for optimal performance, energy efficiency, and emissions reduction, and can be installed within fully prefabricated packaged plant rooms.
Our industrial burners are designed to operate on a wide range of fuel types, including: hydrogen, biogas, natural gas, liquid gases, light fuel oils and heavy fuel oils, and can be supported by gas boosters to maintain stable supply and pressure.
If you are specifying or sourcing an industrial burner, our engineering team can support your decision. Contact Dunphy below to discuss your requirements.
Dunphy’s industrial burners are designed to support a variety of applications, from heat and steam systems to process applications and incineration. These solutions work efficiently alongside industrial boilers for complete energy systems. With capacities ranging from 100 kW to 60 MW, our burners are suitable for all types of gas-fired, steam, and incineration boilers, as well as furnaces.
Since Malcolm Dunphy patented the first axial airflow burner in 1971, we have been at the forefront of energy-efficient combustion technology. Today, our ultra-low NOx burners deliver high-efficiency, low-emission solutions tailored to meet the demands of diverse industrial applications.
An industrial burner is a combustion device that mixes fuel and air in controlled proportions to generate heat for industrial processes. These burners are typically used in boilers, furnaces, kilns and energy systems where consistent, high-output heat is required. Industrial burners are designed to operate with a variety of fuels, including natural gas, hydrogen, biogas and fuel oils, providing reliable heat generation while maintaining efficient combustion and stable system performance.
Industrial burner systems work by mixing fuel and air in controlled ratios to produce a stable and efficient flame. A blower or compressor supplies air, while a fuel valve regulates the fuel flow. The mixture ignites through a spark or pilot flame, generating heat for industrial applications like boilers and furnaces.
Industrial burners are designed to deliver efficient, reliable and adaptable heat for a wide range of applications. By selecting the right burner, operators benefit from lower costs, greater flexibility and improved environmental performance.
Key advantages include:
We offer three types of burners to suit various industrial needs:
Dunphy burners are highly flexible and compatible with a wide range of fuels, including:
Low NOx Combustion
All T-series burners come equipped with low NOx combustion heads as standard, ensuring compliance with emissions regulations.
High Turndown Ratios
Burners achieve up to 12:1 turndown on gas, 4:1 on oil, and 8:1 on oil-fired steam with air atomisation, ensuring efficient operation across varying loads.
Digital Modulation
Fitted as standard, digital modulation ensures high accuracy of control, optimising performance and reducing fuel consumption.
Thorough Testing
Every burner is rigorously tested in our R&D test lab before dispatch, ensuring maximum reliability and performance.
Made in Britain
Designed, manufactured, and assembled at our UK factory, ensuring the highest standards of quality.
Low Noise Operation
The axial airflow design encapsulates the motor and fan within the casting, significantly reducing operational noise levels.
While Dunphy burners are often customised for specific applications, we also offer a range of off-the-shelf features that enhance performance and emissions control:
Oxygen Trim
Adjusts the fuel/air ratio to maintain minimal excess oxygen, enabling consistent combustion with oxygen levels of 2-2.5% across the turndown range. This compensates for fluctuations in fuel calorific value, temperature, and pressure.
CO Trim
Continuously reduces air supply, enabling the burner to operate safely at sub-1% oxygen levels, maximising efficiency while preventing CO formation.
Flue Gas Recirculation (FGR)
Achieves ultra-low NOx emissions of less than 30 mg/Nm³ on gas and 100 mg/Nm³ on oil, enhancing environmental compliance.
Multi-Nozzle Head
Allows for dual or triple fuel configurations, enabling the burner to use multiple fuels either simultaneously or independently.
Industrial burners provide controlled heat for processes such as steam generation, hot water production, drying, brewing, chemical processing, and waste-to-energy applications.
Most industrial burners are designed for natural gas or oil, but many can operate on dual fuel, biofuels, hydrogen blends or even 100% hydrogen, depending on the specification.
By precisely controlling the air-fuel ratio and flame characteristics, industrial burners maximise usable heat, reduce fuel consumption and minimise emissions.
Yes, routine inspection and servicing are essential to maintain safe, reliable and efficient operation, though modern burners are designed to minimise downtime.
Absolutely – low-NOx designs, hydrogen-ready technology and electric options all support decarbonisation and compliance with strict environmental standards.
