Information on oil, gas and dual fuel burners

Industrial burners
Industrial burners sizes 30 to 70 • flexible and reliable
Weishaupt Industrial Burners:
Flexible and reliable
For more than 50 years, Weishaupt industrial burners have set
global standards in terms of reliability, energy efficiency, noise
levels and ease of use.

With firing rate between 3,400 and 40,000 MBH, the spectrum
of application possibilities covers from heating and steam boilers
to air heaters and modern high efficiency boilers.

With its wide range of industrial burners, which can be used with
almost any gaseous or liquid fuel, Weishaupt has the right burner
for virtually any job.

Digital combustion management, included as standard with

industrial burners, contributes not only to the economical use
of oil and gas, but also simplifies the operation and servicing
of the burner. Moreover, the integration into various monitoring
and control systems and into complete building management
systems is made possible.

The clear layout of the burners with their easily accessible

components enables quick and reliable service and therefore
also faster commissioning.

Selected materials combined with experience gained over

decades in a modern research and development centre and
an extensive service network guarantee Weishaupt proverbial
reliability.

With the patented mixing head,

The multiflam® burners therefore com-

The core of multiflam technology is the

specialy designed mixing head, in which

primary flames, making combustion
more efficient then ever before. This is Secondary nozzle 4
achieved by the recirculation of flue Secondary air
