All-round powerhouse up to 32 000 kW. The powerful high-capacity burner.

Digital combustion management, which is included in this range of burners as standard, provides for the economical regulation of gas and oil and simplifies the operation and maintenance of the burner. It also offers the possibility of communication with various monitoring and control systems, up to and including integration into complete building management systems.

The internal insulation reduces the noise level and minimises the surface temperature of the housing when the burner is operating with preheated Combustion air . The burners can be operated with Combustion air  temperatures up to 250 °C.

The fan, control panel, pump station, and preheater station are all sized independently of the burner. This concept offers a large degree of freedom, for example when faced with particularly difficult conditions, such as dust or thermal load.

Weishaupt WK-series burners are available in a range of executions to suit different applications. Various mixing assemblies are available to meet special Emissions  limit requirements. There are also “swirlflame” executions with swirled Combustion air  for extremely short combustion chambers.

Oil-firing WK-series burners are suitable for Class D and Class A2 gas oil per BS 2869 (fuel oil EL and low-sulphur fuel oil EL per DIN 51603-1), and for blended gas oil with a biogenic admixture of up to 99.9 % (fuel oil EL A Bio). FAME per EN 14214 or paraffinic oil (fuel oil EL P per DIN/TS 51603-8) can also be used. Hydrogen blends of up to 20 vol% in natural gas are possible for most gas-firing burners, although in some cases an individual approval inspection might be necessary.

Reliable service and support is available to customers through Weishaupt's comprehensive network. This ensures that systems with a Weishaupt burner always perform reliably.

Weishaupt's patented multiflam^® technology enables large combustion plant to meet very low emission limits.

Key to the system is a special Mixing assembly  that establishes an internal flue gas recirculation. This cools the flame and reduces the formation of nitrogen oxides. The NO_x levels that can be achieved are comparable to those of compact burners.

The various Weishaupt burners that are available in multiflam^® execution cover a range of capacities extending from 100 kW to 23 000 kW.

Weishaupt's 4LN-version burners meet the world's most stringent Emissions  limits. A 4LN-version burner is equipped with a flue gas recirculation system that has its control components integrated into the burner.

Gaseous Fuels  contain almost no sulphur, and so their flue gases mostly comprise Carbon dioxide  (CO₂ ), steam (H₂O), and nitrogen (N₂). This is beneficial to the flue gas recirculation, since there is no ash or soot to contaminate the system.

Special adaptations of the Mixing assembly  together with the W-FM200 digital Combustion manager  ensure a high degree of flame stability and reliable operational behaviour.
