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.
