M.A.S kiln burner

The Mono Airduct System

The patented M.A.S. rotary kiln burner offers essential advantages compared to conventional burner systems. The complete primary air flow is brought into an adjustable swirl with a minimum of losses.

The M.A.S. kiln burner was designed to set new standards in usability and efficiency with the highest effective momentum possible. The system is intended to offer maximum flame control and accuracy in flame setting. This is achieved by using only one single primary air channel which is directly guided into the required swirl.

Especially designed M.A.S. hoses, which can be manually or automatically adjusted, are used to set the swirl angle. This unique flame setting device offers a broader range of settings than any other system and guarantees a controllable and stable flame with any fuel combination. The high fuel flexibility and the remarkable burning results make the M.A.S. burner the most advanced kiln burner available.


  • Highest fuel flexibility
  • Significant decrease in electrical power consumption
  • Simpler and more effective flame shaping
  • Reproducible flame settings
  • Easy burner maintenance
  • Possibility to burn hard combustible fuels

Swirl gas burner SG

The swirl gas burner is an excellent example of an innovative modification of the M.A.S. burner design.

In the new design, natural gas is fed through the flexible hoses instead of primary air. The flame shape is adjusted directly with the fuel and not with the primary air, which is a unique feature worldwide. This design allows maximum flame control with a minimum consumption of primary air. The burner features staged combustion to improve the burning of bright materials such as white cement and lime.

In the first stage the main gas stream is preheated by a short and hot flame at sub-stoichiometric conditions with approximated 5-20% of the total gas amount.

Afterwards the remaining natural gas is completely combusted to maximize the heat transfer to the material.
