D-CBurner

D-CBurner is a high performance and highly flexible burner. The use of advanced software of computational simulations (CFD – Computational Fluid Dynamics) to develop these burners allows the formation of high efficiency flames (specially referring to its shape and length and to the refractory lining durability).

The main characteristics of the D-CBurners are:

  • Low primary air index
  • Multi-fuel (solid, liquid or gaseous fuels)
  • Designed according to fuels to be used and process demands
  • The use of high performance nebulization nozzles for liquid fuels (formation of small droplets
  • Specially designed to have sonic injection of gaseous fuels, allowing maximum gas mixture
  • Designed supported by CFD analysis (quantity of burners and their positioning in the calciner, speed and geometry of primary air injection nozzles, etc)
  • They allow an excelent mixture between air and fuel for a greater combustion efficiency
D-CBurner can be used in
  • Mining
  • Cement

The many benefits of the D-CBurner:

  • High flexibility

  • High flame turbulence

  • High combustion efficiency

  • Reduced NOx and CO emissions

D-CBurner Description

The D-CBurner is used specially in calcination processes (a very common use is in clinker pre-calciners – cement kilns). The separation of primary air into two channels (external air – axial, and tangential air – swirl) provides a greater flexibility to the burner, allowing its adjustments to the process requirements. The use of D-CBurners is quite common for the abatement or reduction of NOx emissions. In these cases, all of its dimensioning (primary air injection nozzle, quantities of burners to be used, their positioning in the calciner, etc) is done by computational simulations ( Computational Fluid Dynamics Analysis – CFD), maximizing the results and assuring that the predicted goal (for example, NOx reduction) is fully achieved.
