DUMAG® Multifuel Burner MFB

Whenever an application requires a stable firing process under demanding conditions achieving a very high turn down ratio, DUMAG’s multifuel burner might be the right answer. In order to meet the target for a cost-effective but still quality driven approach, the fully welded design of the MFB has been reduced to the essential though offering the possibility to operate with two kind of fuels. The sophisticated design allows for the combination of gas-gas or gas-liquid supply at an incredible turn-down ratio for both sources. For this and other sound reasons the MFB has developed to a bestseller in DUMAG’s portfolio.

 

The LowNOx upgrade

If an application requires measures to reduce the NOx to a minimum, the MFB can be upgraded to a LowNOx version MFBX by the means of a staged burner air introduction. Splitting the secondary air portion into partial flows, an internal recirculation can be achieved which inhibits the NOx formation.

Typical applications

The MFB is used as a pilot or supporting burner, a single or dual fuel firing equipment or becomes an integrated part in a stand-alone process solution.
