Weishaupt’s oil, gas and dual-fuel burners

WK 80 industrial burner

The WK80, with a capacity of 22 MW, is Weishaupt’s largest burner. This advanced model is available as a gas, oil or dual-fuel burner and can be operated with all commonly available fuels. The WK80 is the only burner of its type in Europe which is type-tested at the factory prior to delivery.

In its so-called “swirlflame” execution, this burner can now also be used on water-tube boilers with very short combustion chambers. It utilises a newly developed mixing head, which “swirls” the combustion air without compromising flame stability. Tests at the Weishaupt Research and Development Centre have proven that this process works. Facilities here include the world’s largest test-firing chamber that enables such large-capacity burners to be tested at full load.

WGL40 dual-fuel burner

The compact and outstandingly quiet WGL40 dual-fuel burner (125–550 kW) is a completely new type of burner. It features digital combustion management with integrated valve proving and an LCD display for burner setting and control. The burner is equipped with stepping motors for the electronic compound regulation of gas and air. An eBUS interface, a fault output terminal for the logging of error messages and an hours-run counter are included as standard.

The gas valve train includes a multifunction assembly, comprising two class A valves, gas pressure regulator, gas filter and gas pressure switch.

Weishaupt monarch® burners WM (up to 5,700 kW)

The latest Weishaupt WM-series monarch® burners are compact, powerful and quiet. They are writing the next chapter in the 60-year-long success story of the legendary monarch® series. From the very earliest stages of development, particular emphasis was placed on a compact, aerodynamic construction and low operational noise levels. To realise this goal, a completely new air inlet and air damper control were developed. This special housing design with its self-opening air inlet and the new air damper technology result in increased fan pressure and thus in greater capacity despite the burner’s more compact form. The air damper control provides a high degree of linearity even at the lower end of the operating range and, combined with the sound-attenuated air inlet which is included as standard, ensures quieter operation.

All WM burners are delivered with the mixing assembly preset for the required output of the burner. A final adjustment is made using the combustion manager’s menu-controlled commissioning program. Weishaupt WM-series oil, gas and dual-fuel burners are equipped as standard with electronic compound regulation and digital combustion management. Modern combustion technologies demand a precise and continually reproducible dosing of fuel and combustion air. This is the only way optimal combustion figures can be ensured over extended periods. Setting and control of the burner is achieved using a control and display unit. This is linked to the combustion manager via a bus system, enabling the user-friendly setting of the burner.

The integrated interface enables all necessary data and functions to be relayed to a master control system. If required, a telephone connection can be installed to allow for remote operation, monitoring and diagnosis via modem. Several protocols are available via E-Gate or Mod-Gate if data from the burners are to be exchanged with a PLC unit, or if the control of the burners is to be integrated into a building management system. For the control and management levels Weishaupt offers ProGraf NT, a real-time software product that meets any and all requirements.

Digital combustion management makes burner operation simple and reliable. The most important advantages:

• No additional burner controls are necessary as control is effected by the combustion manager. The only additional requirements are external control and motor fuses.
• Reduced installation expense: Each burner is tested and supplied as a complete unit.
• Commissioning and servicing takes less time. The burner’s basic parameters are set at the factory. The combustion manager’s menu-driven commissioning program is used to run through the final site-specific adjustments and the combustion emission checks.
