DRAX Torches - a major new technology for gas burners

DRAX know-how enables a burner using just propane in air to reach higher work-piece temperatures - hot enough to melt steel.

To melt steel, traditional burners rely on high energy mixtures such as oxygen and acetylene to transfer enough heat.

Normal burners using propane/air mixtures have a flame temperature of 1,800 C, which is not hot enough to melt steel.

Oxy-acetylene torches (normal flame temperature 3,000 degrees Celsius) are normally required for heating, cutting and welding steel.

However, steel can now be heated to melting point with propane/air using DRAX technology.

Oxygen and acetylene are expensive, dangerous to store and use, and are not always available. Propane is cheap, much safer to store and use, and is readily available everywhere, making burners using DRAX technology highly attractive.

Technology Thumbnail

A DRAX burner operates by preheating both the air and the propane fuel gas supplied to it.  The energy added in the preheat process augments the flame temperature.  Development work on the implementation of these principles means that this simple concept can now be applied to practical burners. 

Market & Applications

Principal markets for DRAX technology are:

low-cost replacement for oxy-acetylene and oxy-propane torches in industry, engineering/ automotive workshops, and agriculture

easy-to-access technology for occasional and D-I-Y users

appropriate technology for third-world and newly-industrializing economies, reducing dependence on acetylene and using readily-available propane.

Future Development & Opportunities for Collaboration

DRAX technology has been the subject of an extensive development programme, including fundamental research at a major Institute, the University of Southampton, UK.

A patent application, which would protect the technology in all its major markets, has been lodged. A copy of this application is available for download.

The technology is now available for license to burner manufacturers. Initial approaches from distributors with good access to workshop, welding, automotive,  DIY and newly industrializing economies.
