WK-series burners (up to 32,000 kW)

Weishaupt's most powerful burners.

Description

Weishaupt's largest burner: the WK 80 WKG40 gas burner WKL80 oil burner WKGL70 dual-fuel burner

WK-series burners are Weishaupt's most powerful burners. Rated up to 32,000 kW, they have been designed primarily for heavy-duty industrial applications. They are are available as gas, oil, or dual-fuel burners.

 

Modular principle: The fan, control panel, pump station, and preheater station are selected independently of the burner. This concept offers a high degree of flexibility, for example when dealing with difficult conditions such as dust or high ambient temperatures.

Digital combustion management: Digital combustion management, with which this series is equipped as standard, provides economic control of the fuel and simplifies burner operation and maintenance. It also facilitates integration with various monitoring and controls systems, including complete building management systems.

Insulated burner housing: The internal insulation reduces noise levels and minimises the surface temperature of the burner housing during operation with preheated combustion air. The burner can be operated with combustion air temperatures of up to 250 °C.

Tailored versions: WK-series burners are available in different versions to suit different applications. Different mixing assemblies are available to suit particular emission-level requirements. There are also "swirlflame" version burners available, where the combustion air is swirled, resulting in a shorter flame suited to extremely short combustion chambers.

Numerous fuels: There are WK burners suitable for use with light oil, heavy oil, and natural gas, as well as LPG and other fuels.

That's reliability: A comprehensive service and support network is available to customers 24/7, ensuring that combustion plant fitted with a Weishaupt burner always operates reliably.

multiflam®

Weishaupt’s patented multiflam® technology enables large combustion plant to achieve particularly low emissions.

At the heart of the technology lies a special mixing assembly that produces an internal flue gas recirculation. This cools the flame, limiting the production of oxides of nitrogen. NOₓ levels can be achieved that are comparable with the emissions from compact burners.

Good price/capacity ratio: Additional boiler-side equipment, such as external flue gas recirculation, is only necessary when market-specific ultra-low-NOx emission limits have to be met.

Optimal combustion: The mixing assembly distributes the fuel amongst various nozzles. Combustion takes place via a primary nozzle and concentrically arranged secondary nozzles. The primary flame ensures the overall flame remains stable and reliable throughout the whole turndown range.

Highly versatile: The various Weishaupt multiflam® burners together cover a range of 100 kW to 23,000 kW.

Digital combustion technology: The latest technology controls the fuel and air feeds, guaranteeing optimal combustion figures.

Long service life: There are many years of experience and development behind Weishaupt's burner equipment. Only the best quality materials are used in manufacture.

Modern fuels: Weishaupt oil and dual fuel burners are generally suitable for use with light fuel oil (35 second gas oil, low-sulphur gas oil, and B10 biodiesel/gas oil blends).

Efficiency calculator

Weishaupt’s Burner Efficiency Calculator makes it easy to calculate the potential savings that could arise from the use of the latest burner technology.

The Burner Efficiency Calculator makes it easy to calculate the potential savings that could arise from the use of burners equipped with VSD and O2 trim. Upon entering various key data and selecting a load profile, the efficiency calculator recommends a suitable burner from Weishaupt range. It also calculates what additional savings can be made through the use of VSD and/or O2 trim. The potential savings are calculated with reference to local, adjustable energy prices.

The online version of the Burner Efficiency Calculator draws on many factors, of which some can be adjusted, in order to calculate an approximate saving. The Burner Efficiency Calculator Pro used by our advisors enables even more precise adjustments to be made in order to more closely match specific site conditions. This comprehensive calculation is made in consultation with a Weishaupt advisor either on site or in your local Weishaupt office. Why not schedule an appointment with one of our specialist advisors now?

Flue gas recirculation

Current Weishaupt burners in 4LN version meet the world's strictest environmental specifications. Burners version 4LN are equipped with a flue gas recirculation system, whose control components are integrated in a separate fan unit.

Flue gas recirculation for gaseous fuels: Gaseous fuels are almost completely sulphur free. Consequently, the flue gases consist primarily of carbon dioxide (CO2), water vapour (H2O) and nitrogen (N2) and the flue gas recirculation system does not become fouled by ash or soot.

Specially designed mixing assemblies: Specially designed mixing assemblies and digital combustion management ensure that the key characteristics of Weishaupt burners – reliable ignition, a high degree of flame stability, and safe operation – remain very much to the fore.

Dosing: The Mixingbox is worth mentioning. It combines the compact dosing unit for flue gas recirculation and the negative pressure control of the air intake. With this compact fan unit, installation work and commissioning time on site can be reduced.

Control: The FGR system is controlled by the W-FM 200 combustion manager. An additional software module ensures the return of a temperature-compensated volume of flue gas at all operating stages, reliable cold start behaviour, and the highest degree of operational availability.

Weishaupt supports a CHP plant

Approximately 8000 inhabitants in Buch, a suburb of Bietigheim, are supplied with heat and power from the municipal CHP plant. There are many industrial consumers too, including the mechanical engineering and automotive industries. All together, around 42,000 MWh has to be generated every year. Two Weishaupt WK-series burners with variable speed drive and O2 trim help meet peak demand loads, generating around 21,000 MWh of heat energy per year, predominantly with natural gas. The building automation technology is provided by Neuberger, by the way, a Weishaupt subsisidiary based in Rothenburg.
