Commissioning of a Pillard PRECAFLAM™ burner in Mexico 

Fives Pillard commissioned a Pillard PRECAFLAM™ burner in a new cement plant in Mexico, delivered by Fives FCB.                             

Its technology, associated with both the Pillard NOVAFLAM® main burner and the Fives FCB preheater, enables a very low specific heat consumption with an average of 760 kcal / kg.

This 70 MW vertical Pillard PRECAFLAM™ burner is designed to fire coal/petcoke/diesel/natural gas and solid alternative fuel. 

The substitution ratio of the ASF's (Alternative solid fuels) can reach up to 65% depending on the material:

  • With low-weight solid wastes (RDF), the substitution rate can reach 40%
  • With tire chip sizes up to 75 mm, the substitution rate is up to 65% (equivalent to 5 t/h)

During operation, an average O2 < 2.5% is achieved at the preheater outlet, without generating CO.

The Pillard PRECAFLAM™ technology in conjunction with the Fives FCB combustion chamber enables:

  • A reduction of NOx emissions from 1200 ppm to 660 ppm at the preheater outlet
  • An excellent preparation of hot meal for the kiln, with a 5%  increase in production
  • No coating issues, despite using petcoke with a high sulfur content (> 6% S)
