The energy of your developments

Improve your HEATING EFFICIENCY and ensure a CLEAN AND SAFE combustion !

ERATEC designs, manufactures and distributes Metal Fiber Burners (MFB): refractory stainless steel Structure and Bekaert Bekitnit® deck material. 

The metal fibre burner products are used for the premix gas surface combustion

Gas surface combustion is a technique in which premixed gas and air burns on surface layer of a permeable medium. This permeable mat consists of metal wires converted into a flexible and knitted structure. The metalwires are made out of Fecralloy® (a refractory steel with a high temperature corrosion resistance).

Metal Fiber Burners

A complete gas burner unit will consist of the burner and other important devices such as gas controls, air and gas mixing device, fan, ignition system and flame control, and modulation electronics. The metal fibre burner mainly consists of a steel/ceramic housing with the metal fibre medium Bekitnit® mounted on top. Distribution plates are used inside the housing to provide for the homogeneity of the combustion. There are two main types of burners: the atmospheric and the fan-driven burner.


Metal Fiber Burners working mode

Depending on the firing intensity, the combustion can occur in two modes:

- Radiant Mode – Infrared: from 100 till 500 kW/m2

The combustion is made inside the knitted material. The permeable medium then heats to incandescence and releases the majority of the energy input as thermal radiation. Flame colour is red/orange.

- Blue flame mode - Convection: from 500 till 10 000 kW/m2

The blue flames hover above the surface and release the majority of the energy through convection.


The metal fibre burner has several advantages compared to other surface burners, to mention: homogeneous combustion with high modulation rate, high efficiency with low emission rate, low pressure drop, flashback safety, thermal expansion control, resistance to thermal shocks, robustness, fast response and fast cool down.

MFB Shape versatility

The flexibility of the metal fibre media and the procedures for securing it to the housing allow for a wide range of burner shapes and sizes: adapted to the application, Compact, Robust.
