WM-GS20–30 and WM-S10–30 Monarch® burners (100–5600 kW)

Fossil and biogenic fuels:

Higher-viscosity liquid fuels have many different origins. Fossil fuels include residual oils, such as MFO and HFO. Liquid biogenic fuels are predominantly oils produced from rapeseed, soya beans, sunflowers, and oil palms.

• • Petroleum;
  • Heavy fuel oil;

WM-S10 with staged load control

Weishaupt’s high-quality production is not limited to a small number of models. It offers a complete range, including some niche products.

WM-S burners share the many positive features of the WM-L burners on which they are based, including:

• A compact, aerodynamic design;
• Low operational noise levels;
• Digital combustion management with precise dosing of fuel and air;

In addition, they have many other key features, most notably:

• A choice between underslung or side-mounted oil preheater;
• A compact valve block, reducing oil lines to just a supply and return;
• Insulated oil lines;
• A specially designed recirculating nozzle assembly with two or three nozzles;
• A mixing assembly optimised for the fuel to ensure the best combustion results;

WM-S10 burners, which have staged load control, are suitable for oil viscosities up to 75 mm2 /s at 50 °C.

WM-GS20 and WM-(G)S30 with modulating load control

• Control : The following methods of regulation are available for Weishaupt WM-S 30 burners:
  • Oil: Sliding-two-stage or modulating (R), depending on the method of load control employed.

The following methods of regulation are available for Weishaupt WM-GS 20–30 burners:

• • Gas: Sliding-two-stage or modulating (ZM), depending on the method of load control employed.
  • Oil: Sliding-two-stage or modulating (R), depending on the method of load control employed.
• Preheating : The burner’s electric preheater is able to heat high-viscosity oil very rapidly to precisely the required atomisation temperature. This is due to its large heat-exchanging surface in comparison to the relatively small volume of oil. This rapid distribuition of heat prevents any localised overheating that would lead to the ‘cracking’ of the oil.
• Recirculation : The recirculation of heated oil all the way up to the nozzle ensures that oil at the ideal atomisation temperature is available immediately at the time of fuel release / ignition.
• Electrical connection : Local regulations and fusing requirements must be observed when connecting gas, oil, and dual-fuel burners to the electrical power supply.

The most important advantages:

• Burner-mounted oil preheater;
• Insulated oil lines;
• Recirculating nozzle assembly;
• Easy changeover between gas and oil on dual-fuel burners;
• Digital combustion management with electronic compound regulation at all ratings;
• Compact design;
• Sound-attenuated air inlet as standard for quieter operation;
• Powerful fan with specially developed fan geometry and air damper control;
• Electromagnetic clutch included as standard (WM-GS);
• Easy access to all components, such as the mixing assembly, air damper and combustion manager;
• Reliable operation with sliding-two-stage or modulating operation, depending on the burner version and method of load control;
• Computer-controlled function test of each individual burner at the factory;
• Burners can be supplied with pre- wired plug connections;
• Excellent price / capacity relationship;
• Well-established, global service network;
