Multiflam® Burners

The multiflam® principle:

Reduced emissions as standard.

When Weishaupt introduced its multiflam® technology in 1998 it made history, astounding the industry with its unprecedentedly low emissions. Using a patented mixing assembly design, Weishaupt was able to reduce the NOx emissions from large and medium-sized burners to levels that hitherto had only ever been associated with compact burners. Weishaupt set an all-new benchmark, achieving levels below 80 mg/kWh on gas and 120 mg/kWh on oil, subject to the combustion- chamber geometry.

Weishaupt’s multiflam® burners meet the world’s toughest standards. In those countries with particularly stringent environmental legislation, such as Switzerland, multiflam® industrial burners are market-sector leaders.

At the heart of Weishaupt’s multiflam® technology is a special mixing-assembly design which distributes the fuel among primary and secondary nozzles. This results in extremely efficient combustion thanks to recirculation of the flue gases directly at the mixing assembly.

• Gas burner selection – Sizes 60 and 70, version 3LN – multiflam®

Fuels: Natural gas, LPG

Plotted operational ranges represent maximal values measured on idealised flame tubes in accordance with EN 676.

Stated ratings are based on an air temperature of 20 °C and an installation at sea level.

For installations at higher altitudes, a reduction in capacity of 1 % per 100 m above sea level should be taken into account.

Voltages and frequencies: The burners are equipped as standard for three-phase alternating current, 400 V, 3 ~, 50 Hz. Other voltages and frequencies are available on application (no additional cost).

Standard burner motor: Insulation Class F, IP 55 protection, IE3 efficiency at 50/60 Hz (no IE classification at 55 Hz).

* Note regarding G60/1-B 3LN

The burner is equipped with VSD as standard. Its high-capacity fan wheel is

driven by an IP 55 Weishaupt motor operating at 55 Hz when at full speed.

• Dual-fuel burner selection – Sizes 60 and 70, version 3LN – multiflam®

Fuels : Light oil, Natural gas, LPG

Stated oil throughputs are based on a calorific value of 11.91 kWh/kg for light oil.

Plotted operational ranges represent maximal values measured on idealised flame tubes in accordance with EN 676 and EN 267.

Stated ratings are based on an air temperature of 20 °C and an installation at sea level.

For installations at higher altitudes, a reduction in capacity of 1 % per 100 m above sea level should be taken into account.
